In September 2009, SES Americom and SES New Skies merged into SES World Skies.

The company's first satellite; Satcom 1, was launched on 12 December 1975. Satcom 1 was one of the earliest geostationary satellites. Satcom 1 was instrumental in helping early cable TV channels (such as Superstation TBS and CBN) to become initially successful, because these channels distributed their programming to all of the local cable TV headends using the satellite. Additionally, it was the first satellite used by broadcast TV networks in the United States, like American Broadcasting Company (ABC), NBC, a ...

Westar 1 was America's first domestic and commercially launched geostationary communications satellite, launched by Western Union (WU) and NASA on April 13, 1974. It was built by Hughes for Western Union, using the HS-333 platform of spin-stabilized satellites. It operated until May 1983. Mission Westar 1 was the first of five Westar satellites launched by Western Union from 1974 to 1982. Westar 1 was launched from Cape Canaveral on a Delta 2914 launch vehicle from Complex 17 on April 13, 1974. The launch vehicle delivered the satellite to a geosynchronous transfer orbit. After transiting to a near geosynchronous apogee, the satellite employed an apogee kick motor to raise the perigee of the orbit and reduce inclination to near-geostationary. Westars 1, 2, and 3 were 12-transponder satellites while Westar 4 and Westar 5 were launched with 24 transponders. Western Union built a teleport in Cedar Hill, Texas, to uplink content to the Westar satellites (it was interconnected ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Radio Stations and Systems – Article 1.39, definition: ''Broadcasting-satellite service'' The signals are received via an outdoor parabolic antenna commonly referred to as a satellite dish and a low-noise block downconverter. A satellite receiver decodes the desired television program for viewing on a television set. Receivers can be external set-top boxes, or a built-in television tuner. Satellite television provides a wide range of channels and services. It is usually the only television available in many remote geographic areas without terrestrial television or cable television service. Different receivers are required for the two types. Some transmissions and channels are unencrypted and therefore free-to-air, while many other channels are transmitted with enc ...
