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 sub-channel 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 "little 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.
Galaxy 28 is a communications satellite owned by Intelsat located at 89° West longitude, serving the North America and South America market. It was built by Space Systems/Loral, as part of its SSL 1300 line. Galaxy 28 was formerly known as Telstar 8 and Intelsat Americas 8. This satellite provides services in the C-band, Ku-band, and Ka-band.
Galaxy 23 is the name given to the C-band service of the Galaxy 23/EchoStar 9 communications satellite jointly owned by Intelsat and EchoStar located at 121° W longitude, serving the North American market. It was built by Space Systems/Loral, as part of its FS-1300 line. Galaxy 23 was formerly known as Intelsat Americas 13. The "Galaxy 23" portion of the service provides transponders in the C band. The "EchoStar 9" portion broadcasts Ku band, and Ka band transponders.
Galaxy 18 is a Space Systems/Loral (SS/L) 1300-series hybrid communications satellite owned by Intelsat and located in geosynchronous orbit at 123° W longitude, serving the continental United States, Alaska, Hawaii, Mexico, and Canada with 24 C band, and 24 Ku band transponders. Galaxy 18 replaced Galaxy 10R near the end of its design life.
Astra 5A was one of the Astra communications satellites owned and operated by SES at the Astra 31.5°E. Launched in 1997 to the 5° East position by NSAB as Sirius 2, operation of the satellite was transferred to SES in April 2008 and the craft renamed and moved to 31.5° East to open up a new orbital position for the company for the development of markets in Central and Eastern Europe and the Middle East.
The DirecTV satellite fleet is a group of communications satellites located at various geostationary orbits that DirecTV uses for their satellite television service and HughesNet internet service. The "DirecTV" prefix in their names has been changed to "T".
Galaxy 11 is an American geostationary communications satellite which is operated by Intelsat. It is located in geostationary orbit at a longitude of 32.8 degrees east, where it serves as a backup to the Intelsat 802 spacecraft. It was originally operated at 99° West and later spent most of its operational life at 91° West, from where it was used to provide communications services to Brazil and North America.
Intelsat 15, also known as IS-15, is a communications satellite owned by Intelsat. Intelsat 15 was built by Orbital Sciences Corporation, on a Star-2.4. It is located at 85° E longitude on the geostationary orbit. It was launched from Baikonur Cosmodrome to a geosynchronous transfer orbit on 30 November 2009 by a Zenit-3SLB launch vehicle. It has 22 active Ku band transponders, plus eight spares. Five of those transponders are owned and operated by SKY Perfect JSAT Group under the name JCSAT-85.
Intelsat 5 was a satellite providing television and communication services for Intelsat, which it was commissioned by in 2006.
Galaxy 15 is an American telecommunications satellite which is owned by Intelsat. It was launched for and originally operated by PanAmSat, and was subsequently transferred to Intelsat when the two companies merged in 2006. It was originally positioned in geostationary orbit at a longitude of 133° West, from where it was used to provide communication services to North America.
Galaxy 25 (G-25) launched in 1997, the launch was contracted by International Launch Services (ILS), is a medium-powered communications satellite formerly in a geostationary orbit at 97° West, above a point in the Pacific Ocean several hundred miles west of the Galapagos Islands. It was manufactured by Space Systems/Loral, part of its LS-1300 satellite bus, and is currently owned and operated by Intelsat. The satellite's main C-band transponder cluster covers the United States, Canada, and Mexico; its main Ku-band transponder cluster covers the United States, Mexico, and the Northern Caribbean Sea. An additional C-band and a Ku-band transponder pair targets Hawaii.
Telstar is the name of various communications satellites. The first two Telstar satellites were experimental and nearly identical. Telstar 1 launched on top of a Thor-Delta rocket on July 10, 1962. It successfully relayed through space the first television pictures, telephone calls, and telegraph images, and provided the first live transatlantic television feed. Telstar 2 was launched May 7, 1963. Telstar 1 and 2—though no longer functional—still orbit the Earth.
The JSAT constellation is a communication and broadcasting satellite constellation formerly operated by JSAT Corporation and currently by SKY Perfect JSAT Group. It has become the most important commercial constellation in Japan, and fifth in the world. It has practically amalgamated all private satellite operators in Japan, with only B-SAT left as a local competitor.
Galaxy 9 (G-9) was a geostationary communication satellite built by Hughes. It was located at an orbital position of 81 degrees west longitude and was initially operated by PanAmSat and later by Intelsat. The satellite was based on the HS-376 platform and its life expectancy was 15 years. The satellite was successfully launched into space on May 23, 1996, at 01:09:59 UTC, by means of a Delta II vehicle from Cape Canaveral Air Force Station, United States. It had a launch mass of 3080 pounds.
