Iridium Certus®


COMSAT Enhanced Mobile Satellite Services (EMSS)

Iridium Certus

Iridium 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.

Iridium 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 priority across the network.

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