Iridium is the world’s largest commercial satellite constellation providing global mobile satellite communications, including voice and data solutions
This global mobile satellite communications system is owned by the Iridium Communications, Inc. Company based in McLean, VA, United States. The Iridium System is a satellite-based wireless communications network providing a robust suite of data services to virtually any destination anywhere on Earth. Its three principal components are : the satellite network, the ground network and the Iridium subscriber products including ocean platforms fitted with Iridium modems.
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.
