EchoStar IV is a communications satellite operated by EchoStar. Launched in 1998 it was operated in geostationary orbit at a longitude of 77 degrees west for 12 years.
The launch of EchoStar IV made use of a Proton rocket flying from Site 81 at the Baikonur Cosmodrome, Kazakhstan. The launch took place at 23:45 UTC on May 7, 1998, with the spacecraft entering a geosynchronous transfer orbit. EchoStar IV carried 32 Ku band transponders to provide direct voice and video communications to small dishes in North America after parking over 119° W or 148° W longitude. [2]
The Nimiq satellites are a Canadian fleet of geostationary telecommunications satellites owned by Telesat and used by satellite television providers including Bell Satellite TV and EchoStar. 'Nimiq' is an Inuit word used for an object or a force which binds things together. A contest in 1998 was held to choose the name of these satellites. The contest drew over 36,000 entries. Sheila Rogers, a physiotherapist from Nepean, Ontario, submitted the winning name.
EchoStar I is a communications satellite operated by EchoStar. Launched in 1995, it was operated in geostationary orbit at a longitude of 77 degrees west for 12 or 15 years. The company has approved the transfer of the 77 degree west orbital position to QuetzSat as of September 22, 2010.
EchoStar Corporation is an American company, a worldwide provider of satellite communication and Internet services through its Hughes Network Systems and EchoStar Satellite Services business segments. EchoStar is based out of unincorporated Arapahoe County, Colorado.
EchoStar II is a communications satellite operated by EchoStar. Launched in 1996 it was operated in geostationary orbit at a longitude of 148 degrees west for 12 or 15 years.
EchoStar III is a communications satellite operated by EchoStar. Launched in 1997 it was operated in geostationary orbit at a longitude of 61.5 degrees west for 12 years.
EchoStar V was a communications satellite built by Space Systems/Loral based in Palo Alto, CA and operated by EchoStar. Launched in 1999 it was operated in geostationary orbit at a longitude of 148 degrees west. EchoStar V was used for direct-to-home television broadcasting services.
EchoStar VII is an American geostationary communications satellite which is operated by EchoStar. It is positioned in geostationary orbit at a longitude of 119° West, from where it is used to provide high-definition television direct broadcasting services to the United States.
EchoStar VIII was an American geostationary communications satellite which is operated by EchoStar. It is positioned in geostationary orbit at a longitude of 77° West, from where it is used to provide high-definition television direct broadcasting services to the Contiguous United States.
EchoStar XI, also known as EchoStar 11, is an American geostationary communications satellite which is operated by EchoStar on behalf of Dish Network. It is positioned in Geostationary orbit at a longitude of 110° West, from where it is used to provide direct broadcasting services to the United States.
TerreStar-1 is an American communications satellite which was operated by TerreStar Corporation. It was constructed by Space Systems/Loral, based on the LS-1300S bus, and carries E/F band transponders which will be used to provide mobile communications to North America. The signals are transmitted by an 18-metre (59 ft) reflector on the satellite. It had a launch mass of 6,910 kilograms (15,230 lb), making it the second most massive single satellite launched into a geosynchronous transfer orbit, and the second largest commercial communications satellite ever built. Its record as the most massive communication satellite was surpassed by Telstar 19V launched on Falcon 9 on July 21, 2018, with a mass of 7,076 kilograms (15,600 lb).
EchoStar X, also known as EchoStar 10, is an American geostationary communications satellite which is operated by EchoStar on behalf of Dish Network. It is positioned in Geostationary orbit at a longitude of 110° West, from where it is used to provide direct broadcasting services to the United States.
Nimiq-5 is a Canadian communications satellite, operated by Telesat Canada as part of its Nimiq fleet of satellites. It is positioned in geostationary orbit at a longitude of 72.7° West of the Greenwich Meridian. As of July 2015, EchoStar Corporation leases the satellite's entire capacity to provide high-definition television direct-to-home broadcasting for Dish Network Corporation. When accessed using a multi-satellite receiver such as the VIP722k and a multi-satellite dish/LNB combo, such as the Dish-300, Dish-500, or Dish-Turbo 1000.4, the satellite is (incorrectly) referred to by the on-screen diagnostics as Echostar 72 W.
EchoStar XIV is an American geostationary communications satellite which is operated by EchoStar. It is positioned in geostationary orbit at a longitude of 119° West, from where it is used to provide high-definition television direct broadcasting services to the continental United States for Dish Network.
