GEO satellites provide a wide fixed coverage area, making them ideal for sending one signal to a large number of stationary antennas. There were ## fixed satellite services (FSS) satellites in orbit during 2011, providing DTH video, satellite radio, broadband internet, broadcast video distribution, and corporate network connectivity. The dominant providers of international FSS are Intelsat (## satellites), SES (##), Eutelsat (##), and Telesat (##).
The dominant providers of international fixed satellite services (FSS) are Intelsat, SES, Eutelsat, and Telesat. These four companies collectively own nearly half of all GEO commercial communications satellites (## satellites, or ##% of the total), and represented ##% of total FSS market revenues in 2010. The remainder of the market is shared by dozens of smaller operators focused on specific services, regions, or individual countries.
Mobile satellite services (MSS) providers enable users to connect phones and other handheld devices directly to a satellite to provide near-constant coverage, even in places underserved by terrestrial facilities, such as ships at sea, isolated rural villages, polar settlements, or other remote sites. Although they also provide a wide range of routing services to major users such as the U.S. Navy fleet, MSS is particularly useful in the aftermath of natural and man-made disasters when regular forms of communication are often unavailable.
Mobile satellite services (MSS) providers connect phones and other handheld devices directly to satellites to provide near-constant coverage, even in African villages, Antarctic bases, offshore oil rigs, and other remote places not served by terrestrial facilities. The services themselves can include telephone calls, internet access, or mobile television and radio. The satellite fleets can use different orbits ranging from LEO all the way up to GEO.
GEO satellites provide a wide fixed coverage area, making them ideal for reaching a community of stationary antennas that do not need to track a moving object in space. The dominant providers of international fixed satellite services (FSS) are Intelsat, SES, Eutelsat, and Telesat. These four companies collectively own slightly more than half of all GEO commercial communications satellites, and represented ##% of total FSS market revenues in 2008.
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.
