How it works:

The design of the Iridium network allows data to be routed virtually anywhere in the world. Data calls are relayed from one satellite to another until they reach the satellite above the Iridium Subscriber Unit and the signal is relayed back to Earth. Gateways are the terrestrial infrastructure that provides interconnection to the terrestrial data networks. Gateways also provide network management functions for their own network elements and links.

  • 6 polar orbital planes with 11 satellites per plane
  • Low Earth Orbit (LEO) = 780 km altitude
  • Each satellite completely circles the earth once every 100 minutes
  • Each satellite travels from horizon to horizon in 10 minutes
  • The Iridium satellite system uses a frequency band in L band (1616-1626.5 MHz)
