AMC-4 (formerly GE-4 ) is a commercial broadcast communications satellite owned by SES World Skies, part of SES S.A. (and formerly GE Americom, then SES Americom). Launched in 1999, from Centre Spatial Guyanais, ELA-2 by Ariane 44LP H10-3. It provides coverage to North America, Latin America, Caribbean. Located in a geostationary orbit, AMC-4 provides service to commercial and government customers, with programming distribution, satellite news gathering and broadcast internet capabilities. [3]
AMC-4 was launched on 13 November 1999 at 22:54 UTC as GE-4, GE Americom's fourth A2100 hybrid C-band and Ku-band satellite. The C-band payload was home to national television networks broadcasting to thousands of cable television headends. AMC-4's Ku-band transponders served the direct-to-home (DTH), VSAT, business television and broadband Internet market segments. These Ku-band transponders are designed to be switchable between North and South American coverages. [3] It was renamed AMC-4 after GE Americom was bought by SES and re-branded SES Americom. In 2009, SES Americom merged with SES New Skies to form SES World Skies. AMC-4 has been replaced by SES-1 in 2010. AMC-4 has been moved to 134.9° West, and currently has no FTA signals.

SES S.A. is a Luxembourgish satellite and terrestrial telecommunications network provider supplying video and data connectivity worldwide to broadcasters, content and internet service providers, mobile and fixed network operators, governments and institutions.
"Satcom" is also an acronym of, and generic term for, satellite communications
SES Americom was a major commercial satellite operator of North American geosynchronous satellites based in the United States. The company started as RCA Americom in 1975 before being bought by General Electric in 1986 and then later acquired by SES S.A. in 2001. In September 2009, SES Americom and SES New Skies merged into SES World Skies.
AMC-3 is a commercial broadcast communications satellite owned by SES World Skies, part of SES S.A.. Launched on 4 September 1997, from Cape Canaveral, Florida, AMC-3 is a hybrid C-band / Ku-band satellite. It provides coverage to Canada, United States, Mexico, Caribbean. Located in a geostationary orbit parallel to the Yucatán Peninsula and Great Lakes, AMC-3 provides service to commercial and government customers, with programming distribution, satellite news gathering and broadcast internet capabilities.
AMC-11 , previously GE-11, is a American geostationary communications satellite which is operated by SES S.A.. It is currently positioned in geostationary orbit at a longitude of 131° West, from where it is used to relay cable television across North America for onward distribution. It broadcasts to Canada, the Caribbean, Mexico and the United States.
AMC-6, formerly GE-6, is a commercial broadcast communications satellite owned by SES S.A.. Launched on 21 October 2000, from Baikonur Cosmodrome in Kazakhstan, AMC-6 became the fifth hybrid C-band / Ku-band satellite in the GE Americom fleet. The satellite provides coverage to the continental United States, Canada, the Caribbean islands, southern Greenland, and Latin America. Located in a geostationary orbit parallel to the eastern United States coastline, AMC-6 provides service to commercial and government customers, and is used as an Internet platform due to its wide coverage, scale and redundancy. Some of its capabilities include Very-small-aperture terminal (VSAT) networking, satellite news gathering and Ku-band transceiver service. Launched as GE-6, it was renamed AMC-6 when SES took over GE Americom in 2001, forming SES Americom. This merged with SES New Skies in 2009 to form SES World Skies.
AMC-14 is a communications satellite. Initially owned by SES Americom, AMC-14 was designed to be placed in geostationary orbit, following launch on a Proton-M / Briz-M space vehicle. Built by Lockheed Martin and based on the A2100 satellite bus, AMC-14 was to have been located at 61.5° West longitude for Dish Network service.
AMC-7 is a commercial broadcast communications satellite owned by SES S.A., originally from the GE Americom fleet. Launched on 14 September 2000, at 22:54:07 UTC from the Centre Spatial Guyanais in Kourou, AMC-7 provides C-band coverage to United States, Caribbean, Mexico, and is located in a geostationary orbit over the Pacific Ocean east of Hawaii. The satellite is primarily used for cable television programming distribution.
AMC-21, or GE-21, is a American communications satellite operated by SES S.A., formerly SES World Skies and SES Americom. It was launched in August 2008 and is expected to remain in service for approximately 15 years. It is currently located at 125° West longitude.
