COMSAT Certus™

COMSAT has been awarded an exclusive multi-year contract to support all DoD users.

Iridium Certus℠ Network

Certus is the only fully global data and voice network. Satellite and ground redundancy offers exceptional network availability to five nines due to its unique LEO architecture with 66 interconnected satellites (9 in-orbit spares and 6 ground spares) and gateways.

Network Security and Performance

The meshed constellation cross-links provide path resiliency as satellites are linked in front, behind and in adjacent orbits. Rapid satellite transitions and interconnections minimize the impact of network performance anomalies, whilst providing very low probability of signal detection and interception (LPD, LPI.)

Certus terminals are software-defined supporting rapid technology evolution and interoperability to tactical radio nets and commercial terrestrial solutions such as TrellisWare.

Certus offers shorter transmission paths, stronger signals, lower latency and shorter registration time than GEO satellites. This is the only ComSatCom network that lands in a DoD Gateway and the only ComSatCom network that doesn’t traverse foreign soil, furthermore DoD traffic has absolute priority across the network.

Certus is compatible with the existing Iridium network and devices for backwards compatibility and service continuity.

Benefits to DoD Users

  • DoD user beta testing underway, service commences July 2018
  • Purchase hardware, SIM cards and airtime through DISA Storefront
  • All traffic lands at the DoD Gateway in Wahiawa, HI with interconnect to SIPR/NIPR
  • Supports Type 1 and CSfC encryption
  • Traffic does not traverse foreign soil, user terminal connects directly to Gateway via inter-satellite links
  • Iridium Certus RF signaling truly LPI/LPD.
  • 24/7 NOC and Customer Care supported by cleared staff in the US

IP Data

Certus offers background IP and Streaming IP services. Background IP throughput is determined by the terminal class.

Streaming IP Data provides virtual circuits (VC) of; 4.8 Kbps, 9.6 Kbps, 14.4 Kbps, 28 Kbps, 40 Kbps, 56 Kbps, 128 Kbps, 168 Kbps and 256 Kbps.

Streaming IP supports applications such as encrypted voice up to video backhaul from UAVs.

Iridium Certus 2022 / 22 Kbps
Iridium Certus 10088 / 88 Kbps
Iridium Certus 200176 / 176 Kbps
Iridium Certus 350352 / 352 Kbps
Iridium Certus 700352 / 704 Kbps
Iridium Certus 1000512 / 1408 Kbps
