Iridium Satellite Network


Iridium satellite users can rely on the Iridium global satellite network to work everywhere on the planet, when they need it.


About the Iridium Satellite Constellation

The Iridium constellation consists of a fully meshed network of 66 low-earth orbiting (LEO) cross-linked satellites, and 9 in-orbit spares ready to replace any unserviceable satellite. This is how Iridium ensures that every region on the globe is covered by at least one satellite at all times. Iridium satellites orbit at an altitude of 485 miles (780 km), circling the earth once every 100 minutes, travelling at 16,832 miles per hour. Each satellite is cross-linked to four other satellites; two satellites in the same orbital plane and two in an adjacent plane. These links create a dynamic network in space. Messages are routed among Iridium satellites without touching the ground, creating a highly secure and reliable connection. Cross-links also make the Iridium network particularly impervious to natural disasters — such as hurricanes, tsunamis and earthquakes - which can damage traditional land-lines and cell towers

*Although Iridium’s coverage is global, Iridium complies with U.S. embargo restrictions. As such it is prohibited from providing products/service in the following countries: Taliban controlled Afghanistan, China, Cuba, India, Iran, North Korea, Syria and Sudan. Each country is different and regulations may change without notice.
