The BD 1 (Beidou 1) satellites were the 1st phase of the chinese Beidou (Compass) satellite navigation system. The first phase uses only geostationary satellites, in contrast to GPS and GLONASS. This reduces the number of satellites, but limits the coverage to a less than hemispherical area. The basic constellation requires 3 satellites. The satellites are based on the DFH-3 Bus.
Geostationary OrbitAstra 2D is one of the Astra communications satellite owned and operated by SES. Providing digital television and radio broadcast service to the UK and Republic of Island. GE-8 is also a commercial communications satellite operated by GE American, covering the USA, Canada and Caribbean. LDREX was an engineering test to validate the antenna on the ETS-8.
Geostationary Transfer OrbitSatellite Data System (SDS) spacecraft are communication relay satellites for transmitting real-time data from US reconnaissance satellites (e.g. KH-11, Onyx, Topaz) in polar areas. They are also used for communications to USAF aircraft on polar routes and connect the various ground stations of the Air Force Satellite Control Network (AFSCN). The spacecraft relay the downlinked data to a ground station at Fort Belvoir, Virginia.
Geostationary OrbitSTS-97 was a Space Shuttle mission to the International Space Station (ISS) flown by Space Shuttle Endeavour. The crew installed the first set of solar arrays to the ISS, prepared a docking port for arrival of the Destiny Laboratory Module, and delivered supplies for the station's crew.
Low Earth OrbitAnik F1 is a Canadian communications satellite, which was ordered in March 1998. It is based on Boeing's BSS-702 model. The satellite carries 84 active transponders: 36 in C-band and 48 in Ku-band. The spacecraft provides general telecommunications services for North and South America. The satellite was designed for an end-of-life power of 16 kW. Anik F1 was launched in late 2000 on an Ariane-44L H10-3 rocket.
Geostationary OrbitThe QuickBird satellites were commercial Earth imaging satellites with 1 m to 61 cm resolution owned by EarthWatch, later DigitalGlobe. QuickBird 1 launched on a Kosmos-3M from Plesetsk, but was lost due to launch vehicle failure, when the vehicle failed to circularize its orbit. It reentered still attached to the upper stage.
