Iridium is a global communications system that uses a constellation of 66 satellites in a near polar Low Earth'ss Orbit (LEO) with cross-link architecture. Iridium features Subscriber Identity Module (SIM) cards containing all user identification and account information, allowing customized options, shared use, and individual billing.

Iridium system
The Iridium system is a satellite-based, wireless personal communications network providing a robust suite of voice features to virtually any destination anywhere on earth. The system comprises three principal components: the satellite network, the ground network and the Iridium subscriber products including phones and pagers. The design of the Iridium network allows voice and data to be routed virtually anywhere in the world. Voice and data calls are relayed from one satellite to another until they reach the satellite above the Iridium Subscriber Unit (handset) and the signal is relayed back to Earth.
The satellites are in a near-polar orbit at an altitude of 485 miles( 780 km). They circle the earth once every 100 minutes (+ 28 seconds) traveling at a rate of 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. The ground network is comprised of the System Control Segment and telephony gateways used to connect into the terrestrial telephone system. The System Control Segment is the central management component for the Iridium system. It provides global operational support and control services for the satellite constellation,
