Eurostar (spacecraft)
Eurostar is a satellite bus made by Airbus Defence and Space (formerly Astrium, and before 1994, British Aerospace, and Matra Marconi Space (the former Marconi Space having been merged with Matra's former "Matra Espace" division) which has been used for a series of spacecraft providing telecommunications services in geosynchronous orbit (GEO). More than 70 Eurostar satellites have been ordered to date, of which more than 55 have been successfully launched since October 1990 and have proven highly reliable in operational service. In December 2013, the Eurostar satellites accumulated 500 years of successful operations in orbit. The Eurostar spacecraft series is designed for a variety of telecommunications needs including fixed services and broadcast, mobile services, broadband and secured communications. Development Eurostar was designed in the mid 1980s jointly by Matra Marconi Space and BAe (now integrated within Airbus Defence and Space) to Inmarsat specifications, for a market whi ...

Satellite Bus
A satellite bus (or spacecraft bus) is the main body and structural component of a satellite or spacecraft, in which the payload and all scientific instruments are held. Bus-derived satellites are opposed to specially produced satellites. Bus-derived satellites are usually customized to customer requirements, for example with specialized sensors or transponders, in order to achieve a specific mission. They are commonly used for geosynchronous satellites, particularly communications satellites, but are also used in spacecraft which occupy lower orbits, occasionally including low Earth orbit missions. Examples Some satellite bus examples include: * Boeing DS&S 702 * Lockheed Martin Space Systems A2100 * Alphabus * INVAP ARSAT-3K * Airbus D&S Eurostar * ISRO's I-1K, I-2K, I-3K, I-4K, I-6K, and Indian Mini Satellite bus * NASA Ames MCSB * SSL 1300 * Orbital ATK GEOStar * Mitsubishi Electric DS2000 * Spacecraft bus of the James Webb Space Telescope * SPUTNIX TabletSat * ...

Hot Bird
Hot Bird (also styled HOTBIRD) is a group of satellites operated by Eutelsat, located at 13 °E over the equator ( orbital position) and with a transmitting footprint over Asia, Europe, North Africa, Americas and the Middle East. Only digital radio and television channels are transmitted by the Hot Bird constellation, both free-to-air and encrypted. In addition there are a few interactive and IP services. The satellites currently operate at 13° East and are numbered 13B, 13C and 13E. The satellites have been broadcasting digital-only since TV5Monde switched off its analogue signal in 2010. List of satellites Satellite details Hot Bird 1 Hot Bird 1 was launched by Ariane 44LP on 28 March 1995. The 13° east slot predates the launch, with Eutelsat I F-1 having been located there as early as 1983, and EUTELSAT II F-1 having also served time at the location. It has reached end-of-life. Hot Bird 3 Hot Bird 3 was launched by Ariane 44LP on 2 September 1997 and intended to be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
AfriStar
AfriStar (sometimes known as AfriStar 1) is a satellite formerly owned and operated by the company 1worldspace (formerly known as WorldStar) and now owned and operated by Yazmi USA. The satellite was built by EADS Astrium (formerly known as Matra Marconi Space) and Alcatel Space. Based on Astrium's Eurostar E2000+ bus design, the geostationary orbit satellite broadcast digital radio programs in the L-Band frequency (1452–1492 MHz range). Launch Afristar was launched on 28 October 1998 at 22:16:00 UTC, by an Ariane 44L launch vehicle (V-113) from the Centre Spatial Guyanais, at Kourou, since the pad ELA-2. AfriStar was the first WorldSpace satellite. It broadcast digital radio over Africa and the Middle East. Small handheld radios were able to pick up the transmissions from its three L-band beams, each beam covering approximately 14 million km2 on the Earth. The satellite carried from 24 to 96 radio channels with on-board processing to allow variable bit rates from mo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Atlas II
Atlas II was a member of the Atlas family of launch vehicles, which evolved from the successful Atlas missile program of the 1950s. The Atlas II was a direct evolution of the Atlas I, featuring longer first stage tanks, higher-performing engines, and the option for strap-on solid rocket boosters. It was designed to launch payloads into low earth orbit, geosynchronous transfer orbit or geosynchronous orbit. Sixty-three launches of the Atlas II, IIA and IIAS models were carried out between 1991 and 2004; all sixty-three launches were successes, making the Atlas II a highly reliable space launch system. The Atlas line was continued by the Atlas III, used between 2000 and 2005, and the Atlas V which is still in use. Background In May 1988, the US Air Force chose General Dynamics (now Lockheed Martin) to develop the Atlas II vehicle, primarily to launch Defense Satellite Communications System payloads under the Medium Launch Vehicle II (MLV-II) program. Additional commercial and U.S. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Delta II
Delta II was an expendable launch system, originally designed and built by McDonnell Douglas. Delta II was part of the Delta rocket family and entered service in 1989. Delta II vehicles included the Delta 6000, and the two later Delta 7000 variants ("Light" and "Heavy"). The rocket flew its final mission ICESat-2 on 15 September 2018, earning the launch vehicle a streak of 100 successful missions in a row, with the last failure being GPS IIR-1 in 1997. History In the early 1980s, all United States expendable launch vehicles were planned to be phased out in favor of the Space Shuttle, which would be responsible for all government and commercial launches. Production of Delta, Atlas-Centaur, and Titan 34D had ended. The ''Challenger'' disaster of 1986 and the subsequent halt of Shuttle operations changed this policy, and President Ronald Reagan announced in December 1986 that the Space Shuttle would no longer launch commercial payloads, and NASA would seek to purchase launches ...
