A communications satellite is an artificial satellite that relays and amplifies radio telecommunication signals via a transponder; it creates a communication channel between a source transmitter and a receiver at different locations on Earth. Communications satellites are used for television, telephone, radio, internet, and military applications. As of 1 January 2021, there are 2,224 communications satellites in Earth orbit. Most communications satellites are in geostationary orbit 22,300 miles (35,900 km) above the equator, so that the satellite appears stationary at the same point in the sky; therefore the satellite dish antennas of ground stations can be aimed permanently at that spot and do not have to move to track the satellite.
Hot Bird is a group of satellites operated by Eutelsat, located at 13°E over the Equator and with a transmitting footprint over Asia, Europe, North Africa, Americas and the Middle East.
Spacebus is a satellite bus produced at the Cannes Mandelieu Space Center in France by Thales Alenia Space. Spacebuses are typically used for geostationary communications satellites, and seventy-four have been launched since development started in the 1980s. Spacebus was originally produced by Aérospatiale and later passed to Alcatel Alenia Space. In 2006, it was sold to Thales Group as Thales Alenia Space.
Eutelsat 133 West A is a Eutelsat operated Eurobird satellite, used primarily for digital television. It was launched in March 2001, and after a short period testing at 33°E, joined Eutelsat 2F4 at 28.5°E in the Clarke Belt, just within the range of satellite dishes pointed at SES' Astra 2 satellites at 28.2° east. It moved to 33° east and joined Eutelsat 33B in July 2015. Then it was moved to 133° west.
Eurobird was a series of satellites owned and operated by Eutelsat. The Eurobird satellites provided broadcasting and telecommunication services primarily to the Western and Central European region from orbital positions of 9, 25.5 and 33 degrees East. The Eurobird brand was phased out on 1 March 2012, with the satellites becoming part of Eutelsat's main fleet in a company-wide rebranding.
Astrium was an aerospace manufacturer subsidiary of the European Aeronautic Defence and Space Company (EADS) that provided civil and military space systems and services from 2006 to 2013. In 2012, Astrium had a turnover of €5.8 billion and 18,000 employees in France, Germany, the United Kingdom, Spain and the Netherlands. Astrium was a member of Institute of Space, its Applications and Technologies.
Nilesat is an Egyptian company and the name of a series of Egyptian communications satellites. It was established in 1996 with the purpose of operating Egyptian satellites and their associated mission control center and ground stations. The company is owned by the Egyptian Radio & Television Union with a 40 per cent share, the Arab Organization for Industrialization with a 10 per cent share, the Egyptian Company for Investment Projects with a 9 per cent share and the rest is owned by the general public, Egyptian financial institutions and other investors. The company has two ground stations, a primary one in 6th of October City and a secondary ground station in Alexandria. The two ground stations were built by EADS Astrium. Nilesat operates multiple geosynchronous communications satellites, all of which are stationed at 7 degrees West. Nilesat includes as of 17 April 2022 1091 video channels, most of which are free-to-air.
Eutelsat 36A is a French communications satellite operated by Eutelsat Communications. It was constructed by Alcatel Space and is based on the Spacebus-3000B2 satellite bus.
Eutelsat 4A, previously Eurobird 4A and Eutelsat W1 is a French communications satellite which is operated by Eutelsat. It was constructed by Astrium is based on the Eurostar-2000+ satellite bus. Its launch was contracted by Arianespace, using an Ariane 4 44P-3 carrier rocket. The launch occurred on 6 September 2000, at 22:33 UTC from ELA-2 at the Guiana Space Centre.
Hot Bird 7 was a communications satellite that lost in a launch failure in 2002. Intended for operation by Eutelsat, it was to have provided direct-to-home broadcasting services from geostationary orbit as part of Eutelsat's Hot Bird constellation at a longitude of 13° East. Hot Bird 7 was intended to replace the Hot Bird 3 satellite, which had been launched in 1997.
Eutelsat 3D is a communications satellite operated by Eutelsat which will provide services to Europe, North Africa, the Middle East and Central Asia. It will initially be located at 3° E in geosynchronous orbit in a fixed point above the equator, where Eutelsat already has two satellites Eutelsat 3A and Eutelsat 3C. Once Eutelsat 3B is launched in 2014 this satellite will be moved to 7°E.
