Galaxy 26 is a communications satellite owned by Intelsat. It was built by Space Systems/Loral, as part of its SSL 1300 satellite bus. Galaxy 26 was formerly known as Intelsat Americas 6 and Telstar 6. It was launched aboard a Proton-K / DM-03 from Baikonur Cosmodrome, Site 81/23. [1]

It spent most of its operational life at the 93° West longitude orbital position, serving the North American market. Clients included ABC, CBS, CNN and FOX.

The ailing bird

Galaxy 26, known as Telstar 6 at the time, had its share of problems since its 15 February 1999 launch. It had lost a backup command and control receiver, the back up computer, and had completely shut off twice. The satellite first shut down on 22 April 2001 causing the Fox network to relocate feeds to Telstar 5 at 97° West. Then on 11 April 2002 it shut down again and went into a very slow spin. [2]

On 29 June 2008, Galaxy 26 had a power failure in one of its solar panels. It lost 15 kilowatts out of a possible 37 kilowatt capacity, which is very important for charging the batteries. [3] Also, there were multiple transponder failures. Several cable television networks immediately took action to move their feeds to backup satellites in order to keep themselves on air in the event of total failure. Fox News moved operations to Galaxy 16 transponders 7, 9, and 11, and to AMC-5 transponder 4K Slot F according to a Fox News internal email. Within a week, CBS had moved all main feeds to Galaxy 25, and all secondary feeds to Galaxy 28, according to an internal email.

In February 2009, following an urgent call from the Pentagon's Joint staff, Intelsat moved the satellite to the 50.8° East orbital position for use by the United States Department of Defense for unmanned aerial vehicle support. [4] This repositioning of the Galaxy-26, which could be reached by U.S. drone operators by using the relay station at Ramstein Air Base, facilitated the rapid expansion of the U.S. drone program. [5]

End of mission

Galaxy 26 was officially decommissioned on 7 June 2014. [6] The satellite was originally scheduled for decommissioning around 15 March 2014, but that date was extended following delays in the launch of two replacement satellites. [7]

The PBS Satellite Service consists of feeds relayed from PBS by satellite to public television stations throughout the United States. The service was launched in September 1978. The service provides a mixed variety of programming selected from PBS's regular network services. In the X/XP years a satellite feed was multicast by some PBS member stations on an over-the-air DTV subchannel along with their regular programming, or during overnight hours on their main channel to provide a second opportunity for viewers to watch or record primetime programming.

The Anik satellites are a series of geostationary communications satellites launched for Telesat Canada for television, voice and data in Canada and other parts of the world, from 1972 through 2013. Some of the later satellites in the series remain operational in orbit, while others have been retired to a graveyard orbit. The naming of the satellite was determined by a national contest, and was won by Julie-Frances Czapla of Saint-Léonard, Québec. In Inuktitut, Anik means "brother".

Galaxy 4R was a communications satellite operated by PanAmSat from 2000 to 2006, and by Intelsat from 2006 to 2009. It spent most of its operational life at an orbital location of 99° W, a slot once occupied by the Galaxy IV, which suffered a failure in 1998. G4R was launched on April 18, 2000, with an Ariane launch vehicle, and covered North America with twenty-four transponders each on the C- and Ku bands. The satellite was stationed at 76.8°W, inclined.

Galaxy 27 is a communications satellite owned by Intelsat. It was at first located at 129° West longitude, serving most of the North America market. It was built by Space Systems/Loral, as part of its LS-1300 line. Galaxy 27 was formerly known as Intelsat Americas-7 and Telstar-7.
