Iridium Certus 100: Usage, Products and Airtime

Ideal for IoT and M2M Applications

The Iridium Certus 100 service sits between Iridium’s Short Burst Data (SBD) service and the higher throughput of Certus 700. It’s comparable to Inmarsat’s BGAN M2M service; both services utilise the L-Band frequency range, which means antennas can be small and lightweight, and the connection is resilient and stable. Both services are intended for relatively small volumes of data, with Certus 100 offering IP data speeds of up to 88 Kbps (BGAN M2M can offer IP data speeds of up to 464 Kbps).

Certus 100 differs from BGAN M2M due to the difference in satellite orbit height. Certus 100 utilises Iridium’s low earth orbit network, which provides pole-to-pole coverage, and has the benefit of lower latency. Additionally, antennas do not have to be ‘pointed’ to pick up Iridium satellites, which makes this service ideal for mountainous or wooded areas.


Key Information about Certus 100

  • Pole to pole coverage with no ‘line of sight’ challenges
  • Leverages the L-Band frequency – stable and resilient, not susceptible to ‘rain fade’
  • L-Band antennas are small and lightweight, ideal for portable and mobile use
  • Omni-directional antennas with no moving parts
  • IP data speeds of up to 88 Kbps, ideal for SCADA applications
  • Lower latency and less signal attenuation than BGAN M2M
  • Low power, small form factor equipment
  • Easy to deploy with no satellite pointing required.
