Express-A satellites are designed for operation in the fixed satellite service. Their transponder payloads make it possible to retransmit all types of traffic, including television and radio programming, telephony, data, videoconferencing as well as high-speed Internet.
Geostationary OrbitBuilt by Space Systems/Loral (SS/L), Orion 2 features 36 high-powered Ku-band transponders. It was launched into the orbital slot located at 15 degrees west longitude, where in-orbit testing will be conducted. Loral was in negotiations with Eutelsat, also a satellite services provider, to complete coordination of the Orion 2 satellite with the Eutelsat spacecraft in the region.
Geostationary OrbitThe Globalstar global mobile communications network offers global, digital real time voice, data and fax via a constellation of 48 minisatellites. The constellation operates in a 1410 km orbit inclined at 52 degrees, and will also have 8 spares. The satellites were built by Space Systems Loral and Alenia Aerospazio in Rome, Italy.
Low Earth OrbitThe CBERS (China Brazil Earth Resources Satellite) or ZY 1 (Zi Yuan) satellites are designed for global coverage and include cameras to make optical observations and a data collecting system to gather data on the environment. They are unique systems due to the use of on-board sensors which combine features that are especially designed to resolve the broad range of space and time scales involved in the monitoring and preservation of the ecosystem. They are operated jointly by the China Centre for Resources Satellite Data and Application (CRESDA) and the Brazilian INPE (Instituto Nacional de Pesquisas Espaciais, National Institute of Space Research).
Low Earth OrbitTo expand channel capacity and strengthen in-orbit redundancy, DirecTV, Inc., ordered a new satellite from Hughes Space and Communications Company (HSC) in 1998. The new spacecraft, called DirecTV 1-R, is a Hughes HS-601HP model satellite scheduled that was launched in October 1999 under a delivery-in-orbit contract.
Geostationary OrbitLMI-1 (Lockheed Martin Intersputnik) was built by Lockheed Martin Commercial Space Systems and operates at an orbital location of 75 degrees East. Equipped with 44 high-power C- and Ku-band transponders, the satellite provides high-quality and reliable fixed service telephony and direct broadcast television service.
Geostationary OrbitLockheed Martin Commercial Space Systems, an operating unit of Missiles & Space, has revolutionized the space-based imagery market with the development of the first commercial satellite capable of resolving objects on the ground as small as one meter in diameter. The company is providing a spacecraft, designated IKONOS 1, for Space Imaging, Thornton, CO, which offers high-resolution imagery of the Earth to customers around the world.
