Iridium Certus 100 Devices

The Iridium Certus 100 service sits between Iridium’s Short Burst Data (SBD) service and the higher throughput of Certus 700. It utilizes the L-Band frequency range, so antennas can be small and lightweight, and the connection is resilient and stable.

Certus 100 offers IP data speeds of up to 88 Kbps.

The RockREMOTE Series

RockREMOTE delivers a reliable and flexible, IP or message-based, satellite communications solution for fixed, semi-fixed or mobile M2M / IoT applications worldwide.

Customers select between Ethernet, Wi-Fi or Serial RS232/485 for their communications interface requirements. All devices support the new Iridium Messaging Transport (IMT) service which materially lowers the cost of your transmissions, in addition to Iridium Certus 100 (22/88 Kbps).

Benefits of Certus 100 Service

Is Certus 100 the best choice for your IoT connectivity challenge? We’ve outlined some of the key attributes of the service, but if you’d like any advice, please get in touch.

IP-Based for Easy Integration

It’s easy to get going with the RockREMOTE device. It “takes the work out of the comms side for us which can be difficult between Arduino and Raspberry Pi equipment.” The RockREMOTE offers dual-mode satellite and cellular airtime, too, so it’s highly cost effective.

Satellites in Low Earth Orbit

Certus 100 utilizes Iridium’s low earth orbit (LEO) network, which provides pole-to-pole coverage, and has the benefit of lower latency (<1 second). Additionally, antennas do not have to be pointed to pick up Iridium satellites, which makes this service ideal for mountainous or wooded areas.

Supported by Industry Experts

Ground Control’s support team are available to help you at any stage of your IoT connectivity project, from device and airtime selection through to installation, testing and lifetime support. No device leaves our premises without being thoroughly tested, and with the latest firmware installed.

Cost Effective and Flexible Airtime

We can offer great flexibility in our airtime plans, which saves you money. Rather than you paying for data you’re not using, or incurring expensive overage fees, we tailor our plans to your usage. We have very competitive rates thanks to our long-standing relationship with Iridium.

Cloudloop Platform

The Cloudloop platform can be accessed online, or the data retrieved via our fully-featured API. It delivers subscription management, device management, network monitoring and tracking functionality. Cloudloop supports Iridium and Viasat airtime.

Comparing Satellite IoT Connectivity

It’s tricky to compare airtime services because so much depends on how much data you need to send, but as a rough guide, we’ve put together the following comparison points. Get in touch if you’d like any help deciding what will work best for you.
