IoT and M2M Connectivity

We design and build satellite IoT devices so you can retrieve your data from anywhere.
Deserts, forests, oceans, mountains; stationary or mobile; wherever your sensors are.

Our airtime comes from trusted partners like Iridium and Inmarsat, and we offer
free, lifetime customer support, and a world-class device management platform.

Selecting the Right Satellite IoT Hardware & Airtime

These questions are aimed at helping you narrow down your options. We’re here to help, so please contact us if you’d like any support identifying the best solution for your needs.

How data-intensive is your application?
Can your device control your data?
How time-critical is receipt of your data?
Where are your assets, and are they mobile?
low volume icon

Low Volume

E.g. telemetry, sensor data. A few bytes to a few kilobytes.

For low volumes of data, messaging services are highly cost effective. (If you’re not familiar with messaging services, it’s not dissimilar to how SMS works but over satellite). You should investigate Iridium SBD and Inmarsat IDP for critical applications, or cubesats.

medium volume icon

Medium Volume

E.g. audio, images, log files. Kilobytes to a few megabytes.

For medium volume use cases, you should consider Iridium Certus 100 (either IP or IMT) and Inmarsat BGAN M2M.

high volume icon

High Volume

E.g. video. Megabytes to gigabytes.

If you need to transmit high volumes of IoT data, it’s worth exploring Starlink or VSAT solutions.

Rock Devices

Yes icon

Yes

Great, edge computing, reporting by exception and condition-based logging will help reduce the amount of data you need to transmit, potentially opening up messaging services for your application.

Yes icon

No

You could consider a communications device which has edge processing capability such as the RockREMOTE and the RockFLEET.

BGAN M2M Certus 100 Devices

Fast and secure

Mission Critical

If it’s essential that your data is delivered in close to real-time, you need to consider the network maturity, visibility and latency. Iridium-powered devices have the lowest latency and the broadest visibility. Inmarsat BGAN M2M and ScadaSAT by TSAT also offer very low latency and very high reliability of data delivery.

Relatively fast and secure

Useful

If you can wait for your data (i.e. store and forward), you can optimize your delivery, and look at networks that have fewer satellites in orbit (newer LEO constellations like Swarm, for example).

Very fast, very secure

I Operate National Critical Infrastructure

If you operate national critical infrastructure, you may need something with zero reliance on public infrastructure. Have a look at the SCADASat, which gives you a private satellite network.

Fixed mountain icon

Fixed

You’ve got more options as your antenna can be pointed at a fixed point in the sky, opening up geostationary services like Inmarsat. If your location is heavily wooded and hilly, a low earth orbit service like Iridium may be better as satellites are passing constantly overhead.

Mobile cargo ship icon

Mobile

You either need an auto-pointing device to connect with a geostationary satellite (such as Inmarsat) or – and it’s usually a better option – an omni-directional antenna which speaks to a satellite constellation in low earth orbit (such as Iridium) which will retain constant contact with your things as they move.

Polar regions icon

Polar

Only established low earth orbit satellite constellations work well in the polar regions so you’re looking at Iridium.

IoT Connectivity Use Cases

How we Connect Customers with Your Data

Working with Ground Control

Whether you want to self-serve from beginning to end, or tap into Ground Control’s 20-plus years’ of experience, we’ve got you covered.

All of our customers gain free access to Cloudloop. This is our network-agnostic, developer-friendly, subscription, device and data management platform. Integrate directly into your eco system or consume the data via a customer-friendly, data rich UI. Or do both – you choose.

Get inventive

RockBLOCK Plus with captions
What our customers do with our hardware genuinely inspires us. Most applications involve some sort of sensor, a processor to read data from the sensor, and Ground Control providing data transmission. The possibilities aren’t quite endless but they’re not far off!

Feature development is customer-led, so if you’re not sure if our devices can deliver what you need, talk to one of our support team and we’ll see what we can do.

Get value

RockREMOTE plus Cloudloop
Worried about the cost of your satellite IoT connectivity? We get it – satellite has a reputation for being expensive. It’s different with Ground Control, though. We design and build our own devices, so we keep a firm grip on costs without compromising on quality. We have some of the lowest cost airtime service plans available. And with Cloudloop, you can set up alerts if any of your devices are over-spending, and even automatically deactivate them.
