Throughout the world, space policies, strategies, and plans are formalized in documents through which governments communicate the priorities and strategic objectives of their space programs. Space policies describe the overarching approach that guides a country’s space program within the contex… This article is for subscribers. Please sign up for a subscription or login below. Username…
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 (##).
Estimated 2011 revenue for satellite communications reached $## billion, #% higher than the $## billion for 2010. The satellite communications segment includes both fixed satellite services and mobile satellite services. FSS refers to the delivery of satellite communications to stationary ground receivers that can be moved from one location to another but do not work while in transit. MSS systems can maintain a communications link with a mobile receiver, and include applications such as satellite telephones or in-flight communications. Both types carry video, voice, and data.
The satellite services sector, which includes fixed and mobile satellite services, registered $## billion in 2010 revenue, up from $## billion in 2009. Both types of services communicate information in video, voice, and data formats. Fixed satellite services (FSS) refer to the delivery of satellite communications to stationary ground receivers that can be moved from one location to another but do not work while in transit. Mobile satellite services provide similar capabilities but the communication link ties to mobile receivers, such as satellite telephones or in-flight communications.
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 (125 satellites, or 47% of the total), and represented 49% of total FSS market revenues in 2010.
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.
Satellites have provided trunking for long-distance telephone service for decades. Most long-distance traffic is now routed over cable, avoiding the lag and other reductions in quality (such as echo) associated with satellite telephone calls. Areas or countries lacking terrestrial backbone still rely on satellite connectivity to the publicly-switched telephone network. Telephone companies or nations lease C-band or Ku-band transponders on GEO satellites. Telephony, along with broadcast television, discussed above, and data services are common FSS applications.
