Water utilities worldwide are under increasing pressure to deliver more with less. Ageing infrastructure, growing demand, environmental challenges, and regulatory compliance all demand smarter, more efficient operations. Yet many of the most critical water assets, including pipelines, reservoirs, pumping stations, and metering points, are located in remote or rural areas where conventional cellular connectivity is either unreliable or unavailable.

This connectivity gap has long been a barrier to digital transformation in the water sector. Without reliable communication between remote assets and central systems, utilities face costly manual inspections, delayed responses, and fragmented data. Satellite IoT is helping to bridge that divide, bringing off-grid infrastructure online and enabling smarter, more efficient operations. While proprietary satellite IoT has served this role for decades, a newer, standards-based alternative is now emerging: NTN NB-IoT (Non-Terrestrial Network Narrowband Internet of Things).

NTN NB-IoT, part of the 3GPP standard for satellite-enabled IoT communications, allows connected sensors to communicate with satellites using the same NB-IoT protocol, and chipset, that they would use to connect to a terrestrial network. Economies of scale means that this drives down the cost of the chipset, delivering lower hardware costs, and potentially lower airtime costs too. For water utilities, this unlocks applications that might have been cost-prohibitive prior to the advent of standards-based satellite IoT.

At Ground Control, we specialize in enabling satellite-based connectivity and telemetry solutions for critical infrastructure. As NTN NB-IoT technology matures, we’re perfectly positioned to help water utilities leverage it to extend smart monitoring and control to the very edges of their networks. Here’s how NTN NB-IoT differs from proprietary satellite IoT and where it adds value to smarter water utility operations.

Rethinking Remote Connectivity

As water utilities continue to extend monitoring and automation efforts in remote and rural environments, satellite communication has been, and remains, critical to bridge connectivity gaps where cellular networks are unreliable or unavailable. Until very recently, the only option for utilizing satellites was to use a proprietary satellite module, e.g. if you wanted to utilize the Iridium satellite constellation, you would need an Iridium module.

These proprietary solutions are are built for purpose; the designers have not had to limit their modules’ capabilities to the 3GPP standard, which of course started as a cellular standard. This means you can send more data, more quickly, through a proprietary solution.

Further, if you’re using a message-based proprietary solution, such as Iridium’s Short Burst Data service, Iridium Messaging Transport (IMT), or Viasat IoT Nano, you also get the benefit of power efficiency.

Proprietary solutions, therefore, have been a trusted option for many years, providing reliable, low bandwidth satellite communication for mission critical data such as flow rates, tank levels, pump status, and alarm notifications. They have proven particularly valuable for applications requiring near real-time data or coverage in truly isolated areas.

However, when it comes to massive IoT deployments, proprietary solutions have limitations. Relatively high device and airtime costs, and proprietary integration requirements can make services like SBD, IMT and IoT Nano challenging to deploy at scale, particularly for low-power sensor networks or distributed metering systems.

Enter NTN NB-IoT (what is NTN NB-IoT?).

Proprietary-vs-NTN-NB-IoT

For water utilities, NTN NB-IoT could be a breakthrough. Water utility providers can deploy NTN NB-IoT-enabled sensors, meters, and monitoring equipment in places that were previously cost-prohibitive to connect via proprietary satellite IoT.

What are the Applications for NTN NB-IoT in Water Utilities?

For a water utility weighing NTN NB‑IoT against higher‑bandwidth proprietary satellite links, the sweet spot is infrequent, small payload telemetry where truly global reach (no cell towers) matters more than millisecond alerts. Typical deployments include:

Daily or multi‑hour meter reads
Remote or off‑grid customer meters (flow, volume) that only need to report once or twice a day for billing or usage analysis. A 200 byte payload can easily carry several readings, supporting rural homes, farms, or remote industrial sites.

Tank level and reservoir monitoring
Track water levels, detect overflow risks and monitor usage trends in storage facilities far from population centers. Gravity‑fed storage tanks in remote service areas report level and temperature every few hours – enough to plan refills without real‑time urgency.

Environmental baseline sensing
pH, turbidity, conductivity or chlorine residual sensors on remote intakes or treatment sites. These can trickle in (no pun intended!) once per shift or per day to track long term trends, enabling insight into water quality, and supporting regulatory compliance.

Pump run‑hours and basic status
Hourly or daily “I’m alive” heartbeats plus simple ON/OFF or run‑time counters to track remote booster stations or solar powered pumps, helping to reduce downtime and extend the life of critical infrastructure.

Pipeline integrity logs
Low frequency pressure, flow rate and structural vibration snapshots in isolated, hard to access terrain, allowing early detection of leaks, bursts or blockages to reduce water loss.

Asset inventory and location
Periodic GPS pings and motion/tamper alerts from mobile test vans, valve exercise robots or floating sensors in open canals, optimizing maintenance schedules and improving operational security.

Beyond NTN NB‑IoT: Scenarios Requiring Real Time Satellite Links

Here are the water‑utility applications that really demand real time links and higher data volumes – i.e. where you’d reach for a proprietary satellite IoT service such as SBD, IMT or IoT Nano, rather than NTN NB‑IoT:

Instant leak/failure alerts
Continuous pressure or flow monitoring that must trigger sub‑minute alarms when a burst or major leak occurs.

Remote valve actuation and control
Two‑way commands (open/close, throttling) with confirmation feedback to isolate sections of pipe or adjust flow on demand.

SCADA‑style telemetry
High frequency readings (e.g. every few seconds or minutes) from multiple sensors (pressure, temperature, vibration) at booster stations and treatment plants.

Video or acoustic inspection
Transmitting snapshots, short video clips or high‑resolution acoustic signatures from remote intake structures or pipeline inspection robots.

Predictive maintenance analytics
Bulk uploads of rich sensor datasets (e.g. vibration spectra, pump performance curves) to cloud analytics for failure prediction.

Bi‑directional firmware updates and diagnostics
Pushing larger firmware or configuration payloads OTA (over the air), plus logging back detailed health / status reports in real time.

Event‑driven sampling
Millisecond‑resolution burst data (e.g. transient pressure spikes) that need to be streamed offsite immediately for analysis.

Benefits-of-Proprietary-Satellite-IOT

Emergency backup SCADA link
A full‑bandwidth failover channel when terrestrial SCADA lines go down, to keep control room visibility alive.

These use cases all hinge on low latency, two way communication and/or bulk data transfers; capabilities that proprietary satellite IoT is designed to deliver.

What is NTN NB-IoT?

Simply, NTN NB-IoT allows data to travel over satellite using the same standard as terrestrial NB-IoT. This means that the same chipset can be used for satellite or cellular connectivity, leading to lower hardware costs, and potentially, lower airtime costs.

It doesn’t, however, mean that it is identical to terrestrial NB-IoT, and network architects need to bear its limitations in mind. We’ve outlined some of the key differences in the following table:

NTN NB-IoT (via Skylo)

Cellular NB-IoT

Proprietary Satellite IoT

Max Practical Payload

256 bytes

1,400 - 1,600 bytes

100,000 bytes

Latency

High (10 - 60 s); MVNO scheduling ⟶ 2 - 5 min

Low (1 - 10 seconds)

Medium (c. 10 seconds)

Directionality

Bidirectional (protocol level) but uplink-focused in practice

Bidirectional

Bidirectional

Coverage

United States, Canada, Brazil, Australia, New Zealand and select European markets

Terrestrial (nationwide but no maritime/remote)

Global

Typical Transmissions Per Day

Common MVNO plans: ~1 - 3 uplinks/day (entry tiers)

No strict cap: supports thousands to tens of thousands of uplinks/day (limited only by data plan allowances)

No strict cap; governed by data plan allowances

In summary, users can anticipate smaller data volumes, and intermittent data transmission (e.g. a few times per day), allowing devices to operate for years on battery and solar power. NTN NB-IoT is, therefore, ideal for low bandwidth, low power, and long life IoT applications.

A Smarter Approach to Connectivity

NTN NB‑IoT shines when you need occasional, small payload uplinks from truly off-grid assets. Its standards based 3GPP Release 17 stack makes integration straightforward, devices run for years on battery, and you can monitor things like daily meter reads, tank levels, water‑quality snapshots or pump “heartbeats” in remote terrain without laying any infrastructure.

Proprietary satellite IoT earns its keep when you need low latency, high volume, two way links, for real time leak/failure alarms, remote valve control, SCADA‑style bursts, video or acoustic inspections, large OTA updates, and emergency failover.

With decades of experience in satellite communications, Ground Control offers more than just connectivity; we deliver complete, integrated solutions from device to cloud.

One of the most disruptive threats to commercial and military maritime operators is the manipulation of Global Navigation Satellite Systems (GNSS), primarily by low-cost GPS jammers, state-sponsored GPS spoofing campaigns, and cyber-physical interference. From oil tankers seized via spoofed coordinates to cargo ships disappearing from satellite tracking due to jamming, the vulnerabilities of GNSS reliant systems are no longer theoretical, they’re operational hazards. These disruptions compromise navigation, safety, and compliance monitoring, particularly in high-risk regions such as the Baltic Sea, Eastern Mediterranean, and other areas with geopolitical tensions.

GPS Jamming Issue Grows in Eastern Mediterranean and Black Seas
Daily, October 1, 2023 – April 4, 2024

Growing Number of GPS Jamming Attempts

GNSS/GPS manipulation has far-reaching implications, from compromised navigation to operational disruptions. While there are various satellite-based techniques for detecting spoofing and jamming, RockBLOCK Pro STL offers a truly resilient, unjammable alternative. In this blog, we explore how it works and why it matters.

Key Differences Between Jamming and Spoofing

Jamming

Spoofing

Definition

Overwhelms GNSS signals with noise to block reception

Sends fake GNSS signals to mislead the calculation of a false position/time

Mechanism

High-power RF signals on GNSS frequencies disrupt signal acquisition

Fake signals mimic legitimate ones, often stronger, to deceive the vessel

Goal

Denial of service (DoS) – prevents GNSS-based operation

Deceives the receiving vessel into believing a false position or time

Effect on receiving vessel

Loss of satellite lock; receiving vessel cannot determine position/time

The receiving vessel continues to operate, but with incorrect data

Detection Difficulty

Often easy to detect due to complete signal loss

Harder to detect, may go unnoticed as the vessel operates normally

Signal power

High (to overpower weak satellite signals, typically > -100 dBm)

High (to overpower weak satellite signals, typically > -100 dBm)

Legality

Illegal in most countries

Also illegal, often more complex to execute and trace

Hardware Requirements

Relatively simple - can be handheld or vehicle-mounted

More complex, requires GNSS signal generation and precise timing

Use Cases (Malicious)

Disrupt vessel navigation, leave crew and cargo vulnerable to attack

Mislead ships, expose ships to hijacking, steer vessels into dangerous waters

Implications for the Shipping Industry

The interception and denial of GNSS/GPS connectivity pose significant risks to the commercial shipping industry. GPS spoofing, for example, misleads shipping vessels into believing they are on a safe course when, in reality, they may be heading into dangerous waters or restricted areas. Reports indicate that vessels in the Eastern Mediterranean have been falsely located at airports, and other instances have shown ships being misled into high-risk territories. Many vessels, especially those without backup navigation systems, are vulnerable to these attacks.

In July 2019, the UK-flagged oil tanker Stena Impero, operated by Stena Bulk, was seized by Iranian forces while transiting the Strait of Hormuz. Investigations suggest that the vessel’s navigation systems were subjected to GPS spoofing, causing it to deviate into Iranian territorial waters. Analysis of AIS data indicated anomalies consistent with spoofing attacks, where counterfeit signals misled the ship’s navigation systems. This incident highlighted the vulnerabilities in maritime navigation and the potential for state actors to exploit them.

Later in 2019, vessels operating near Chinese ports, particularly around Shanghai, reported widespread GPS anomalies. Ships experienced sudden changes in reported positions, with some appearing to move erratically or vanish from tracking systems. Investigations revealed that these anomalies were due to GPS spoofing attacks, affecting hundreds of vessels and disrupting port operations. The incidents raised concerns about the potential for such attacks to be used for strategic or economic purposes, with the United Nations urging the protection of satellite navigation from interference.

Spoofing and Jamming Detection via Satellite

Satellite systems can detect GNSS/GPS spoofing and jamming by identifying inconsistencies via a number of indicators and parameters.

Positional behavior can indicate spoofing or jamming. Satellite systems can identify positional and movement abnormalities and send alerts when ships “jump” positions, show physically impossible maneuvers, such as a 90° turn at high speed, or appear in two locations simultaneously, known as ghost ships. Further, comparison with terrestrial radar and sensors is a method of spoofing detection. Satellites compare reported Automatic Identification System (AIS) data with ground radar or visual surveillance, and mismatches may indicate spoofing.

To avoid and prevent spoofing and jamming attacks, commercial shipping companies can support risk-based routing. Here, shipping companies use historical spoofing “heat maps” to reroute vessels around known interference zones, such Baltic Sea, Eastern Mediterranean, and any other region or zone with geopolitical tensions.

These detection techniques are effective, but the vulnerabilities of GNSS/GPS signals remain. A secure and unjammable solution is required for complete visibility and confidence of vessel positioning at sea.

STL For GNSS/GPS Independence at Sea

While satellite-enabled detections exist to combat traditional GNSS/GPS spoofing and jamming, STL (Satellite Time and Location) via the Iridium network offers an uncontested solution – a secure, unjammable, encrypted alternative for acquiring positional, navigation and timing (PNT) information anywhere in the world.

STL is a one way, encrypted signal broadcast via the Iridium satellite constellation,1,000 times stronger than GPS, making it far more resilient to jamming. Leveraging Iridium’s LEO satellite constellation and thus, a signal 25 times closer to the Earth than GNSS, STL delivers accurate time and position data without needing traditional GNSS visibility, giving commercial ships and maritime systems trusted positioning even when GPS is denied.

Although STL provides an independent signal, it is notable that it is not designed to replace GNSS, rather, it’s designed to complement it. STL can be accessed from the same receivers as GNSS and GPS, making it easy to incorporate as part of a layered approach to reliable, secure and unjammable tracking and positioning.

GNSS _ SLT Diagram

How RockBLOCK Pro Utilizes STL for Unjammable Maritime Tracking

RockBLOCK Pro STL is a ruggedized, compact satellite-based tracking solution that harnesses the power of STL to deliver a secure signal independent of terrestrial or GNSS infrastructure. This PNT service offers an alternative when GPS or GNSS Global signals are absent, denied, or disrupted.

Traditional GPS signals are vulnerable and easy to overpower or imitate with spoofing equipment. STL, by contrast, resists these threats through encryption so spoofers cannot easily mimic the signals. Complementing traditional GPS / GNSS and delivering a reliable backup, RockBLOCK Pro STL enables transmission of vessel location updates even when GPS / GNSS is being denied, spoofed, or jammed.

This is vital for commercial ships as well as vessels transiting piracy or cyber-prone regions, unmanned surface vehicles (USVs) operating in contested waters and NATO and allied vessels conducting patrols in high-risk areas.

RockBLOCK-Pro-Web-Angled

The technology encapsulated within RockBLOCK Pro STL is designed for ease of integration with existing maritime equipment. The solution delivers RS232 / RS485 and USB-C serial interfaces for easy integration with existing hardware, IP66 waterproofing – ideal for harsh marine conditions – and a compact, low-power design for permanent and portable deployments. It’s a secure and rugged solution for shipping companies to tackle the ongoing threat of GPS spoofers and jammers.

Operational Scenarios with RockBLOCK Pro STL

There are several operational scenarios where RockBLOCK STL provides an uncontested, reliable solution to GPS-denied environments, spoofing, and jamming:

Anti-Spoofing for Cargo Ships: A container vessel approaching a spoofing hotspot in the Eastern Mediterranean receives conflicting GPS signals. RockBLOCK Pro STL continues to deliver trusted positioning, allowing the bridge crew and HQ to detect the spoof and maintain safe routing.

Naval Operations in Denied Environments: A patrol vessel operating under electronic warfare conditions near contested maritime borders loses GPS functionality. Utilizing RockBLOCK Pro STL, onboard systems retain accurate time and position data, crucial for navigation, targeting, and tactical coordination.

Unmanned Maritime Drones: An autonomous surface vessel in the Arctic Circle cannot acquire GPS due to interference. RockBLOCK Pro STL ensures connectivity, continuity and remote GPS monitoring via Iridium.

Secure Positioning When GPS Goes Dark

From bulk carriers drifting off-course in the Black Sea to naval vessels being targeted in the Red Sea, GNSS/GPS interference has shifted from a rare anomaly to a strategic weapon. The rise of low-cost jammers, state-sponsored spoofing campaigns, and cyber-physical interference has exposed a serious blind spot in global shipping: overdependence on vulnerable, unprotected GNSS/GPS satellite signals. RockBLOCK Pro STL provides an essential layer of protection, ensuring a secure, unjammable and critical connection to vessels at sea.

With RockBLOCK Pro STL, Ground Control offers a compact, secure, and rugged satellite-based solution that ensures maritime assets stay online, stay located, and stay safe, even when GPS goes dark.

Direct-to-Direct (D2D) satellite connectivity is one of the most talked about innovations in IoT right now. It promises seamless global coverage, allowing connected devices, from smartphones to smart sensors, to communicate with satellites without the need for additional hardware such as a specialized antenna.

At first glance, D2D sounds like the ultimate solution for remote IoT applications. But there’s a problem: the term is being used too broadly and too optimistically. Many assume that D2D is synonymous with standards-based satellite IoT, like NTN NB-IoT or LTE Cat-1 over satellite. In reality, these are adjacent but distinct technologies, each with very different capabilities, timelines, and trade-offs.

In this post we’ll cut through the noise to discover what’s actually available today, and what will be available in six months, one year, and beyond. We’ll look at the benefits and limitations of D2D, and explore whether you would be better off focusing on standards-based satellite IoT as you consider what’s best for your IoT deployment.

What Direct-to-Device (D2D) Actually Means

Direct-to-Device (D2D) connectivity means that a device – typically a smartphone – can communicate directly with a satellite (part of a non-terrestrial network, or NTN) without requiring additional external hardware like a specialized antenna / dongle.

D2D is a capability, not a standard. It means a device can talk directly to a satellite, but that doesn’t necessarily mean it uses NB-IoT or LTE.

The most well-known example is Apple’s agreement with Globalstar. Newer iPhones embed chipsets that allow them to access the Globalstar satellite constellation where available. This is a proprietary technology, meaning iPhones cannot connect to other satellite networks.

While still relevant, the Globalstar/Apple partnership is an outlier. Today, D2D is often referenced in the context of standards-based connectivity – but that’s where definitions start to blur.

D2D and Standards-Based Connectivity: Not the Same Thing!

Standards-based NTN connectivity refers to satellite networks that adhere to existing cellular standards, e.g. NB-IoT and LTE Cat 1.

A key benefit of this is that you don’t have to modify your data to send it through a proprietary satellite protocol. Standards-based connectivity also opens the door to switching networks for broader coverage or better pricing – a flexibility not available with proprietary solutions.

But here’s the key distinction:

D2D

Standards-Based NTN

D2D is about the physical capability for a device (e.g., smartphone or sensor) to connect to a satellite without extra hardware.

Standards-based is about ensuring that the satellite connection adheres to existing cellular protocols like NB-IoT and LTE Cat 1.

The connection can be proprietary or standards-based.

Compatible devices may still require separate hardware to connect, especially today.

Pure D2D for IoT is limited today and requires ideal antenna positioning and sky visibility.

You can access standards-based NTN today, usually via an external transceiver / dongle.

What’s Available Now (Early 2025)?

There are two cellular standards being adopted by satellite network operators: NB-IoT and LTE Cat 1.

  • NB-IoT uses very little bandwidth and is being rolled out by providers like Iridium and Viasat to complement their proprietary solutions.
  • LTE Cat 1 requires more bandwidth and is being pursued by newer entrants like Starlink and AST SpaceMobile, who partner with mobile network operators (MNOs) to access spectrum.

 

The standard closer to delivery is NTN NB-IoT. Skylo is not a satellite network operator, but has done a lot of work to make NB-IoT work over existing satellite networks. They have partnered with multiple satellite networks, including Viasat and Ligado Networks, to bring a solution to market in the USA, Canada, Australia, New Zealand and Brazil.

Some satellite network operators are already offering this service in a limited capacity – Sateliot were among the first to market with a proposition. However, they’re in the process of scaling their satellite IoT services; initial store-and-forward services are available, but fully operational coverage will be c. 2028.

At the moment, the hardware being built for IoT tends to take the form of a unit that can be attached to a sensor or gateway to facilitate NTN connectivity.

Why is Separate Hardware Still Needed for IoT?

  • Many sensors or gateways don’t yet support NTN NB-IoT or LTE Cat 1 and will need to pass data through a connected device which can re-format the data to work with the appropriate standard.
  • Satellite connectivity requires a clear view of the sky. Devices embedded in machinery or under panels (like an OBDII port or solar-powered sensor) are unlikely to maintain a reliable satellite link.

What Will Be Available In Six Months (Mid-Late 2025)?

In terms of NB-IoT, Viasat’s “IoT Direct” is currently in beta mode, before a full release in the second half of 2025. This will deliver global NB-IoT capabilities for connected devices, and we’re particularly excited about this development.

We also expect the first LTE Cat 1 service for IoT from Starlink to be available before the end of 2025. Starlink’s “D2C” model depends on cooperation from mobile network operators, and rollout will begin in countries with large land masses and low population density, where unused spectrum is more available.

Current rollout countries are the USA, Canada, Australia, New Zealand, Chile, Peru, Ukraine, Switzerland, and Japan.

What Will Be Available in One Year?

We should see more integrated, true D2D devices that can connect to both cellular and satellite networks using standard protocols, without needing separate antennas. But these are unlikely to be materially lower cost than the current, proprietary options available. This is because it is both economies of scale and competition that drives prices down, and that will take a little longer to come to fruition.

Starlink will likely have its first competitor in the LTE space (no pun intended) with the commercial launch of AST SpaceMobile anticipated in early 2026. However, AST SpaceMobile is focused squarely on the cellphone market rather than IoT devices; it will probably be another 12 months (early 2027) before IoT devices can connect to the AST SpaceMobile network. It’s also worth mentioning that AST SpaceMobile also needs agreements with MNOs to deliver its service; it will not be global at launch.

The Future (2-5 Years)

The update that allowed cellular standards to be used over satellite is called 3GPP Release 17. While Rel-17 made it possible to use cellular standards in satellite communication, it didn’t make it easy, with companies like Skylo having to do a considerable amount of engineering to make NB-IoT transmissions over satellite a reality.

Iridium, currently the world’s only global satellite IoT network, was a little late to the party in developing a standards-based proposition, but now that it is, it’s working very closely with the 3GPP to extend the functionality of NTN NB-IoT. This collaboration means that 3GPP Release 19 (anticipated in late 2025) will remove many technical challenges and hasten the widespread availability of industry standard chipsets.

Availability of Standards-Based NTN Services

*3GPP compliant release 10 or newer, modem must support existing bands of operation in intended service countries

We also anticipate that we’ll see increased data throughput, greater power efficiency, and lower latency as these advanced protocols coupled with new satellite modems filter through, enabling smaller, lower cost and longer lasting IoT devices.

The reason this falls into the 2-5 years section is because the benefits take several years to reach end users. Firstly, network operators, device manufacturers and other industry stakeholders will need time to implement the new standards, which can involve significant hardware and software updates, plus extensive testing.

Deployment of the new technology across networks is often piecemeal, too, rolled out across regions and service providers at different times – meaning that it will take time to become widely available. And, of course, end users’ devices must be compatible with the new standards; this will include firmware changes to support the lower speeds and smaller message sizes available over NTN NB-IoT.

While NB-IoT remains the most popular choice for delivering NTN standards-based connectivity, by this time we’d anticipate also having IoT propositions from AST SpaceMobile and Lynk using the LTE Cat 1 standard. These new satellite network operators, along with Starlink, will undoubtedly create more commercial agreements with mobile network operators, extending the reach of NTN LTE Cat 1 services.

What Should IoT Businesses Do Now?

It depends on the criticality and data requirements of your application. While NTN NB-IoT services are reaching the market, the throughput is very small, and data transmission is infrequent, so it best serves applications where there are a high number of end points, but real-time information is not required (e.g., livestock tracking, environmental monitoring, agriculture, basic fleet management, and wearables).

Massive IoT vs Critical IoT Diagram

If this describes your application, get in touch with a service provider like Ground Control to get advice on the best network and hardware for your application. Note that this will almost certainly involve additional hardware, as the satellite industry is some way from solving the issues around device compatibility and antenna siting mentioned earlier.

If you need higher volumes of data and closer to real-time data, you will still be better served by a proprietary solution such as IMT / Certus 100 from Iridium, or IoT Nano from Viasat. These services are well established and globally available; they will co-exist alongside the standards-based solutions for the foreseeable future.

Finally, don’t get too preoccupied with D2D; it offers exciting possibilities, but it’s still a developing technology that won’t be widely available for some time, and will only be appropriate for certain use cases.

Ground Control’s tracking platform, Cloudloop, now supports Globalstar’s GSat Solar and SmartOne C tracking devices. The integration provides a budget friendly satellite tracking option for businesses and organizations that need occasional location updates without the expense of more advanced two-way communication systems.

This integration expands the range of options available through Cloudloop Tracking, allowing users to deploy low power, long lasting satellite tracking solutions that are ideal for monitoring assets in remote or off grid locations where cellular coverage is unreliable or unavailable.

Globalstar-Logo

Globalstar operates a constellation of Low Earth Orbit (LEO) satellites, providing cost-effective tracking solutions for businesses. Devices transmit location and status updates to the satellite network at predefined intervals, and in the case of the selected hardware, only send data one way. While this has some limitations (they’re not suitable for real-time tracking of high value assets), it means the devices are significantly cheaper than two-way communication alternatives. They also draw very little power, and can run for years without maintenance, making them ideal for remote asset tracking. Their compact size and flexible mounting options also make Globalstar trackers easy to install on various assets.

Globalstar’s services are regionally available, mainly in North America, Europe, and parts of South America (see coverage map).

Why Choose Globalstar for Asset Tracking?

Lower Cost, Simple Tracking

Globalstar’s tracking solutions provide a cost-effective way to monitor assets that do not require real-time oversight. If you need to be 100% certain of an asset’s position at all times or require two-way messaging, other solutions (like Iridium-based tracking) will be more suited. However, compared to premium two-way satellite tracking solutions, Globalstar devices significantly reduce tracking expenses while still offering a reliable means of monitoring asset movements. For businesses managing large fleets of lower-value assets, the cost savings can be substantial.

Battery Powered and Compact

Both the GSat Solar and SmartOne C are designed for easy deployment without the need for a constant power source. The GSat Solar harnesses solar energy, making it an excellent choice for long-term, low-maintenance tracking. The SmartOne C, on the other hand, operates on replaceable batteries, ensuring flexibility for different use cases where solar charging may not be practical or possible. Their compact form factors also make them easy to install on a variety of asset types, such as shipping containers, vehicles and even animals.

 

Globalstar Tracking Devices

GSat Solar

GSat Solar is an ultra-low power, solar powered tracking device designed to provide long term asset visibility with minimal maintenance. With its solar-powered operation, GSat Solar ensures extended battery life, reducing the need for manual intervention and making it a reliable choice for long term deployments.

Critical national infrastructure is an increasingly attractive target for state-sponsored activists and extremist groups. Remote infrastructure – everything from outstations to wind farms, wellheads to pump stations, haul roads to transport hubs – is particularly vulnerable because of the challenges in creating robust security solutions in these locations. This blog post seeks to present a solution to these challenges, but first, let’s dig into the issues in more detail.

The Growing Threat to Remote Infrastructure

The vulnerability of utility and energy production sites to cyber attacks is well documented; from 2023 to 2024, US-based utilities experienced a 70% surge (Reuters). Less frequently reported is that physical attacks on infrastructure also rose 73% from 2020 to 2022 (Axios), with incidents including a gunfire attack on two substations in North Carolina, USA, which left 45,000 customers without power.

In Nigeria, in early 2024, the power sector faced escalating vandalism of high-voltage transmission infrastructure; incidents tripled during a 15 week span, including explosives being used to destroy transmission line towers (The Electricity Hub).

In Australia, thefts from unmanned construction sites reached a 10 year high in September 2024, with a 22% increase in theft-related offences during the same period (Herald Sun). And in the UK, the cost of theft of agricultural equipment escalated to an estimated £52.8 million in 2023, a 4.3% increase from the previous year (NFU).

In addition to a growth in isolated incidents is the underlying strategy to destabilize infrastructure, driven by alliances between state actors like Russia, and organized criminal gangs. These activities include sabotage, arson and cyber attacks, aimed at undermining critical infrastructure (The Guardian).

Attacks are increasing: companies, governments and individuals with hard-to-protect, high value assets are fighting a rising tide of criminal activity.

The Challenge of Traditional Security Measures

The infrastructure we’re describing here – transport, energy production, heavy industry – operates across vast areas, making it impractical to station physical security at every location which could be a target. Assuming a single security guard is stationed at a site for 8 hours a day, 7 days a week; the cost of an unarmed guard would be c. $3,600, and c. $6,000 for an armed guard (Deep Sentinel).

Statistically, most theft takes place after dark, and are more frequent in winter; long weekends and holidays are also attractive (Site Watch Group). Thus, 24 hour cover would be prudent at least over weekends, adding substantially to the cost.

Security-Guard-in-Remote-Location-shaded-blue

Another option is to use fences coupled with cameras and sensors to detect intruders, and provide real-time alerts to a remote monitoring center. The security personnel there can monitor multiple sites remotely, reducing on-site staffing costs. Upon receiving an alert, they can choose to dispatch security personnel to the affected site, alert local law enforcement or trigger some localized deterrent such as alarms, voice sirens or lights.

The pros of this approach is that it’s lower cost, delivers 24/7 surveillance, and can be rapidly and cost-effectively scaled up. However, it requires a reliable, secure and cost-effective means of transmitting the video stream (and potentially also audio and movement sensors). Within cellular connectivity this is pretty straightforward, but in a remote site, satellite is often the only viable option.

Remote-Surveillance-Smart-Fence-shaded-blue

Finding the Right Satellite Connection for Remote Surveillance

Satellite connectivity isn’t a homogenous blob. There are multiple radio frequencies used, and the type used strongly influences the form factor of the satellite transceiver. For example, people seeking broadband internet access over satellite – Starlink, Hughesnet, OneWeb etc. – will be using Ka-band, as this supports higher data rates, and there’s plenty of bandwidth available (i.e. limited congestion issues).

The drawback of Ka-band is that it is both susceptible to rain fade (signal loss in bad weather), and the antenna size is large, power hungry, and needs to be precisely positioned. This is not an issue for home installation, but in a remote outstation, there may be mountains, trees or the outstation itself preventing the ideal siting of the antenna.

The fix to this – phased array antennas which electronically steer themselves to optimal positions – has the drawback of consuming significantly more power. Indeed, it would be challenging to power any Ka-band antenna via a solar-powered battery, particularly for the sorts of continuous operation that a surveillance system requires.

Satellite Frequency Bands

Satellite services that operate in the L-band spectrum, on the other hand, have very small antennae, and low power requirements compared to Ka-band. Iridium and Viasat (previously Inmarsat) utilize L-band for data transmission, which makes them perfect for IoT applications where the data requirements are lower, and a small, discreet, battery-operable antenna is an asset – sometimes a necessity. L-band transmissions are unaffected by weather conditions, and very hard to intercept, making them ideal, in principle, for mission critical applications like remote surveillance.

However, video streaming from remote, potentially unpowered locations, is an awkward fit for both Ka- and L-band. It’s a high bandwidth transmission, but as discussed, high bandwidth satellite services are power hungry, easy to identify (and therefore to put out of action), and difficult to position. L-band fixes all those challenges, but to send video over L-band, which is a much more constrained frequency band, is very expensive.

Until now…

A Breakthrough in Remote Video Surveillance

There have been two key developments that have made it possible to send video over an L-band satellite connection cost-effectively. The first is the advent of low bandwidth video. Our partner Videosoft has developed video compression and transmission technology that delivers real-time, low-bit rate video. They’ve coupled this with an image enhancement feature that lets users specify and download high-res pixels from an area of interest in a scene.

Videosoft’s technology works with most off-the-shelf hardware, including video cameras, CCTV, audio microphones, GPS tracking antennae, and other I/O devices.

Watch Videosoft Demo

The second development is the availability of midband (higher throughput) transmissions in the L-band spectrum; notably Viasat’s IoT Pro service, and Iridium’s Certus 100 service. The latter is particularly well suited to remote surveillance because the satellites are in Low Earth Orbit, which means the latency is very low – critical when you need real-time alerts if a facility has been penetrated, or an asset is moving outside of schedule. 

Additionally, Iridium has a cross-linked network of 66 satellites, which means you don’t need to point your antenna at the satellite; if your facility or asset is in a wooded or mountainous area, this could be a critical advantage. 

RockREMOTE Rugged: A Simple and Secure Solution

There are a number of Iridium Certus 100 transceivers available – we design and build several ourselves – but the one we’ve focused on for remote surveillance is the RockREMOTE Rugged. This is because, most importantly, it has the compute power to natively run the Videosoft program without needing any additional hardware. It’s simply a matter of plugging your camera into the RockREMOTE, and working through some simple config steps to get started.

RockREMOTE Rugged is very easy to install; it’s IP67 rated, and designed for permanent outdoor installation in harsh environments. Its omni-directional passive antenna is small and discreet, making it harder to identify by bad actors.

RockREMOTE Rugged

Thus, securing a remote site becomes smarter and more cost effective. Choose from a very wide range of cameras, audio equipment, motion detectors etc., then plug them in to the RockREMOTE Rugged. The onboard Videosoft technology will compress the data so it can be sent cost-effectively over the Iridium Certus 100 network, in real-time, to your remote monitoring center.

A Smarter Approach to Remote Security

Protecting remote infrastructure has never been more critical – or more challenging. While traditional security measures struggle to balance cost and coverage, the combination of low-bit rate video, real time image enhancement, and power efficient satellite connectivity presents a game changing solution.

With RockREMOTE Rugged and Videosoft’s technology, organizations can deploy surveillance systems that are reliable, cost effective, and optimized for remote environments. Whether safeguarding critical national infrastructure or protecting high value assets, this technology ensures security teams have the visibility they need, when they need it most.

Undersea internet cables are essential for global communications and economic security. The entire global network of cables is more than half a million miles long and comprised of more than 200 independent but interconnected systems. These cables span vast distances, connecting continents and enabling everything from international internet services to military communications. But with increasing geopolitical tensions and the growing importance of digital infrastructure, the threat to these cables has risen on the international agenda.

The strategic importance of undersea cables, which carry 99% of international telecommunications, makes them attractive – and vulnerable – targets.

In January 2025, the Royal Navy closely monitored the Russian vessel Yantar, officially an ocean research ship but considered a spy ship, as it entered UK waters and mapped underwater infrastructure.

Additionally, a NATO flotilla, including ships from the Netherlands, Germany, and France, assembled off Estonia to protect undersea cables in the Baltic Sea from potential sabotage, primarily by Russia.

Guard and patrol vessels play a pivotal role in deterring and responding to potential threats, ensuring the integrity of essential communication networks.

Map-of-Undersea-Cables-2

Data from the TeleGeography Submarine Cable Map shows that damage to undersea cables is a common occurrence. According to a report by the International Cable Protection Committee (ICPC), around 300 cable breaks are reported every year. Most of these are accidental, caused by fishing trawlers, ships’ anchors, or natural events like earthquakes. However, the risk of deliberate attacks or sabotage by state or non-state actors is also increasing.

The potential for geopolitical tensions to spill into the maritime domain has been highlighted in various reports. For instance, the United States Department of Defense (DoD) has raised concerns about the vulnerability of critical undersea infrastructure to foreign adversaries. This type of attack can have devastating effects on global data flow, cybersecurity, and national security.

Internet traffic, military transmissions and financial transactions all depend upon submarine cables, so any disruption can cause significant economic damage, loss of access to critical services, and widespread instability in communication.

Undersea-Cables

The Role of RockFLEET in Securing Submarine Cables

Guard boats are increasingly deployed as vital protectors of undersea cabling infrastructure. These guard boats, often repurposed fishing vessels, act as sentinels over subsea cables, ensuring their security by warning nearby vessels to keep a safe distance.

Tracking guard boats efficiently in remote and challenging maritime environments requires an advanced tracking solution. RockFLEET is a compact, robust, and highly reliable tracking device designed specifically for use in harsh maritime conditions. It operates through satellite-based communication via the global Iridium network, ensuring seamless tracking of guard boats even in areas with no cellular coverage, anywhere in the world.

This capability is essential as guard boats often patrol vast stretches of ocean far from terrestrial networks. With RockFLEET, maritime authorities and operational teams can monitor the precise location of each guard boat, ensuring the vessels are where they need to be to protect the cables effectively.

RockFLEET-Being-Held-by-Sailor

Three Ways RockFLEET Supports Guard and Patrol Vessels

Real-time Positional Data

One of the key features of RockFLEET is its ability to provide real-time positional data, which allows maritime coordinators to track the movement of guard boats and assess their effectiveness in securing undersea cables. If a guard boat drifts away from its designated patrol zone, RockFLEET alerts the operational team, enabling quick corrective action. This constant monitoring ensures that no section of the subsea cable remains unprotected due to navigational drift or unforeseen circumstances.

Estimated Arrival Times

Another critical function of RockFLEET is providing estimated arrival times (ETA) for guard boats. When repositioning guard boats due to shifting threats, adverse weather conditions, or maintenance schedules, knowing the vessel's precise ETA is crucial. RockFLEET transmits accurate ETA data, allowing for better planning and coordination. This information helps ensure that there are no gaps in cable coverage and that another vessel is available to take over if one needs to leave its position.

Enhanced Vessel Safety

Safety is also a significant concern for guard boat crews. Since these vessels often operate in remote and sometimes hazardous conditions, having a reliable tracking system ensures that their locations are known at all times. In case of an emergency, RockFLEET provides real-time location updates, enabling rapid response and assistance from support teams. This enhances the overall security of both the vessels and the critical cabling infrastructure they protect.

The Future of Undersea Cable Security

As the threats to undersea cables continue to evolve, governments, cable operators, and multinational organizations are increasingly prioritizing the security of this infrastructure, given its direct impact on everything from national security to economic stability. New initiatives like the UK’s ‘Nordic Warden‘, which aims to track the movement of vessels suspected of malicious damage, should enable faster response times.

Guard boats and patrol vessels in their preventative capacity will remain an essential part of this response. RockFLEET plays an essential role in ensuring the effective tracking and monitoring of guard boats tasked with the protection of undersea cables. By providing accurate location tracking, monitoring movement, estimating arrival times, and enhancing overall vessel safety, RockFLEET helps to safeguard the vital cable infrastructure that underpins global communication and commerce.

Protect Critical Infrastructure with Smarter Maritime Monitoring

As threats to undersea cables and maritime assets increase, guard and patrol vessels play a crucial role in safeguarding global communications. Our advanced satellite tracking and monitoring solutions ensure these vessels operate with maximum efficiency, real-time situational awareness, and enhanced safety – no matter how remote the mission.

What is D2D?

D2D refers to the ability for an unmodified device – such as a cellphone – to access satellite connectivity. This was pioneered by Apple and Globalstar as they partnered to provide an emergency satellite communication service for iPhone users in 2022.

How Does D2D Work?

There are two ways D2D can be delivered. The first is by building a chipset into the device that allows it to access a specific satellite network. This is the option chosen by Apple, and its satellite network partner Globalstar. The benefit of this approach is that Globalstar has licensed radio spectrum that allows it to provide a service anywhere where it has a satellite overhead. The downside is that the device can only communicate with a single satellite network.

The second way to deliver D2D is to adapt the satellites themselves so that they are compatible with the communication protocols already in use by cellphones and other devices – i.e. 4G, 5G etc. This is the approach chosen by Starlink, AST SpaceMobile and Lynk, all of whom are in the process of launching satellites compatible with terrestrial network communication standards.

The benefit of this approach is that, in theory, all compatible satellite networks are available to the cellphone user as simply another network on which to roam, and they can do so depending on what their commercial agreement is with their usual network service provider (e.g. Vodafone, AT&T etc.).

The downside is that because these are new satellite networks, they do not have licensed radio spectrum through which to deliver their service; this is already distributed among older, more established satellite constellations. So to deliver service, the new satellite network operators need to partner with a terrestrial network operator to ‘borrow’ some of their licensed radio spectrum. Services are only available where these partnerships exist, so they are not global. Starlink, for example, has partnerships in 10 countries; outside of these countries, it cannot provide service.

How Could D2D Benefit Lone Workers?

In 2021, we asked lone workers across multiple industries if, as part of their job, they sometimes or often travelled out of cellular coverage. 51% responded yes. We then asked about the implications of this; did they ever feel unsafe, for example, or been unable to send or receive a message when they needed to.

Statistics on Lone Worker Safety

 

As the graph illustrates, lone workers operating in areas without voice, text or internet services feel – and are – more vulnerable. 15% of the overall workforce are considered lone workers, and NSC data indicates that working alone increases both the likelihood of incidents, and the severity of adverse outcomes.

Although we can’t draw a parallel, it’s striking that industries with a high number of lone workers – Utilities & Renewables, Oil & Gas, Forestry, Emergency Response, Community Healthcare – are also struggling with staff retention.

 

While it’s not a silver bullet, the benefits of lone worker monitoring technologies are well documented: improved safety outcomes and staff morale, leading to greater staff retention, and saved costs in recruitment and insurance premiums.

An estimated 2.3 million lone workers in Europe, North America, and Australia & New Zealand now have access to a lone worker safety solution, with the market estimated to grow at a rate of 7.1% between 2024 and 2029 – further indication of the value of these platforms.

But if they can’t be accessed because the worker is outside cellular coverage, they fail. D2D with its ability to confer internet access to any compatible cellphone with a relevant commercial agreement, unlocks the ability to access these platforms from very remote locations where cellular coverage is nonexistent.

Why Your Cell Phone May Fail You

The problem with D2D is not the service, it’s the cellphone. Relying on a standard smartphone for emergency or indeed routine satellite communication comes with significant weaknesses, especially when it comes to the device’s physical vulnerabilities. Here’s why your phone may not be the most reliable option when you need it most.

Overheating and
Thermal Shutdowns

Satellite connections require the phone to transmit at higher power levels, which generates more heat than cellular communication. Many phones will automatically shut down when internal temperatures exceed safe limits, leaving users without a means of communication.

View Data Source

Drop and
Impact Vulnerability

A cracked screen or internal damage from a fall can render a phone unusable, preventing emergency communication. Even flagship smartphones can shatter from waist-high drops, whereas ruggedized satellite communicators are built to withstand extreme impacts.

View Data Source

Battery Drain and Cold Weather Failure

Phones in satellite mode will often use higher transmission power and spend more time searching for signals, draining the battery faster. Further, cold weather severely affects lithium-ion battery performance.

View Data Source

Lack of Physical Controls for Emergency Use

In emergency situations, speed matters. Unlike dedicated satellite devices, which often feature an SOS button that can be activated instantly, smartphones rely on touchscreen controls that may be difficult to use with wet, cold, or gloved hands.

View Data Source

Weak Antenna and Poor Signal Reception

Smartphones' internal antennas are optimized for terrestrial networks, meaning signal reception in satellite mode will often be weaker and less reliable. Dedicated satellite communicators feature larger antennas that ensure consistent connectivity even in difficult environments.

In this integration, we’re bringing together two proven technologies to solve a common challenge in remote monitoring: reliably transmitting environmental data from locations with no terrestrial connectivity.

The Campbell Scientific CR1000 is a widely used data logger known for its durability and flexibility in harsh environments. By pairing it with the RockREMOTE Mini, a compact satellite modem supporting both IP and IMT communication over the Iridium Certus 100 network, we enable robust, low-power data transmission from virtually anywhere on Earth. This document outlines how the integration works, the benefits of each device, and the steps to get a system up and running.

Note: while our testing was with the CR1000, this solution will also work with the newer Campbell Scientific data logger models: CR1000x and CR1000Xe.

 

Why the Campbell Scientific CR1000 Series is so Prolific

The CR1000 and its successors are renowned for their versatility, reliability and robust performance in harsh environmental conditions. They support a wide range of sensors and communication protocols, making them the go-to choice for remote sensing applications. With CRBasic programming, data collection and processing can also be customized to meet specific needs, enabling bespoke, efficient, and reliable monitoring in a range of diverse scenarios.

Whether monitoring water quality or glacier temperatures at Mt. Everest, their ability to collect and process data has made them a cornerstone of environmental monitoring systems worldwide.

When paired with RockREMOTE Mini, the CR1000 becomes a truly global resource, capable of operating autonomously in even the most remote and harsh locations. By combining these two devices with a modest solar solution, users can deploy a fully self-sustaining system that ensures reliable data monitoring and access anywhere in the world, even in areas where no terrestrial networks are available.

Campbell Scientific CR1000 Data Logger

Introducing RockREMOTE Mini

RockREMOTE Mini is an efficient and compact satellite communications modem designed for connecting devices where terrestrial networks are unavailable. It utilizes the Iridium Certus 100 service and can send data over both IMT (Iridium Message Transport) and IP (Internet Protocol). This allows you to take advantage of the easy and standards-based approach of IP for a PoC and then leverage the efficiency of IMT when scale is required.

With both Serial Communication (RS232/RS485) and Ethernet (with PoE+) available, the Mini is straightforward to integrate. The Mini’s Sleep pin allows for dynamic power management, which is particularly beneficial for solar-powered or battery-operated deployments. The Mini has a very low standby draw of only 300 mW while still being able to receive communications. It can be advantageous to put the Mini to sleep when power is at an absolute premium. An inbuilt GNSS receiver allows the Mini to provide a time source for multiple connected devices.

RockREMOTEMini - Certus 100 Satellite data transfer device

While it’s very straightforward to integrate the RockREMOTE Mini with your hardware, it is equally simple to get or view your data with our Cloudloop platform. You can use Cloudloop Data to view the data directly or have Cloudloop forward the data to your server. Crucially, Cloudloop functions as a translator between Iridium’s IMT protocol and many of the web standards that you are familiar with, for example, HTTP webhook, Azure Queue, MQTT, ThingsSpeak, AWS SQS & S3, to name a few. This means that integration is fast and efficient, allowing you to utilize the most efficient protocol for the satellite portion of the network and the most convenient one on the server side.

For IP, Cloudloop NOC provides clear packet tracing and troubleshooting, including the ability to set Inbound and Outbound firewall rules to ensure your device is protected and set up for your requirements.

Cloudloop Device Manager can also be used to manage devices by updating their firmware and configuration over the air, ensuring they remain up-to-date without requiring physical access.

 

Iridium Messaging Transport (IMT) vs IP

We have discussed using the most appropriate transport method for different parts of the network. This is crucial for keeping airtime costs down while also allowing for easy development. The table below gives a quick overview of the differences. Cloudloop enables you to benefit from the upsides of both.

Iridium Messaging Transport (IMT)

IP-Based Communication

Data Size

Small to medium data packets (max 100 KB per message)

Larger data transfers (unlimited size)

Cost

Lower cost per message (no headers, data only)

Higher cost per message (headers, TCP/UDP)

Use Case

Periodic sensor readings, status updates, scheduled reporting, configuration changes

Real-time monitoring, program updates, large chunks of data transfers, and constant reporting

Integration

Requires CRBasic formatting to implement the AT prefix

Seamless - plug and play

RockREMOTE Mini operates over Iridium’s Certus 100 Network, offering speeds of 22 Kbps up and 88 kbps down to the remote terminal. IP is ideal for quick and easy integration with existing systems, leveraging standard TCP/UDP protocols, as well as Outbound, Inbound Port Filtering, and Port Forwarding.

In contrast, IMT is a message-based protocol that transmits data in Base64 format, eliminating the overhead of headers and limiting the message size to 100 KB. While IP requires no additional development work, IMT involves creating a CRBasic program to communicate with the Mini over a serial port using an AT syntax. This can add complexity, but it provides complete control over the transmitted data, making it a cost-efficient option for low-bandwidth applications.

For example, if an application involves transmitting temperature readings from a dozen sensors every hour, IMT would be the most cost effective option. On the other hand, if you need to update the CR1000’s program remotely, retrieve a whole day’s worth of data, or monitor the data constantly, IP would be the better option. This highlights the flexibility of the RockREMOTE Mini since it can communicate both over IP and IMT at the same time.

 

How we Integrated the RockREMOTE Mini and CR1000

1. Connections:

  • Connect the Mini’s brown Sleep pin to the CR1000’s C1 for power control
  • Connect the Mini’s orange 0V-REF pin to the CR1000’s Ground
  • Temperature sensor to 1H and 1L on the CR1000.

 

2. Serial Communication (for IMT):

  • Mini communicates with the CR1000 via COM2 at 115200 baud
  • Connect TX (CR1000) to RX (Mini) and RX (CR1000) to TX (Mini).

 

3. Ethernet Communication (for IP Inbound/Outbound Port Configuration):

  • Connect the Mini’s Ethernet port to the CR1000 or a local switch
  • Assign a static IP to the CR1000 in the Mini’s network range (e.g. 192.168.250.2).
