Introduction to IRIDIUM Networks

The Iridium System is a satellite-based, wireless communications network providing a robust suite of Voice and Data services to virtually any destination anywhere on earth.

With 66 satellites forming a cross-linked grid above the Earth, the Iridium system is the first low-earth orbiting system for telephone service. Only 780km (450 miles) high, these satellites work different from those at a much higher orbit (26,000km) in two major ways. First they're closes enough to receive the signals of a handheld device; and second, they act like cellular towers in the sky - where wireless signals can move overhead instead of through ground based cells.
