While FSS systems all operate in GEO, mobile satellite service (MSS) systems operate in a range of orbits. Some MSS operators have built their networks using a limited number of GEO satellites. In August 2008, the oldest and largest of these, Inmarsat, launched its ## Inmarsat-4 satellite, establishing global availability of its Broadband Global Area Network (BGAN) service, and bringing the fleet total to ## spacecraft. Another GEO MSS operator, ICO Global, launched its G-1 satellite in April 2008 to provide voice, data, video, and Internet service throughout the United States on mobile and portable devices.

GEO satellites provide coverage of a wide area from a relatively fixed position, making them ideal for broadcast applications to multiple downlink sites, as well as for networking services to widely dispersed corporate and government facilities. Video distribution, point-to-point video feeds, also known as “backhauls,” and Direct-To-Home (DTH) television services represented three-quarters of total satellite services revenues in 2007.
