Iridium’s constellation consists of 66 Low-Earth Orbiting (LEO), cross-linked satellites operating as a fully meshed network and is supported by multiple in-orbit spares. It is the largest commercial satellite constellation in the world.

Iridium is the only provider of truly global satellite voice and data communications solutions with complete coverage of the entire Earth including oceans, airways and even Polar Regions.

Tens of thousands of aircraft are currently equipped with Iridium-based systems and nearly half of the traffic on the Iridium network comes from international waters.

Iridium provides service to subscribers from the U.S. Department of Defence (DoD), as well as other civil and government agencies around the world.

Voice services are provided via dedicated handsets, or through a variety of installed communications systems onboard ships, aircraft and land-based vehicles.

Specialized devices incorporating Iridium’s 9601 short burst data (SBD) transceiver provides packet data connections for the transfer of location information, weather reports, email, or any other data requiring a reliable, global, two-way connection.

In the machine-to-machine sector, the Iridium constellation provides mobile data links for asset tracking and other monitoring applications.
