In November 1991, PanAmSat Corporation ordered three Hughes HS-601 model PAS (PanAmSat) satellites from Hughes Space and Communications Company. The satellites provide video services for program distribution and syndication; data services for business applications; and services for video, radio, data and telephone transmission. They were placed over the Pacific, Atlantic and Indian oceans, respectively. In August 1993, PanAmSat ordered a fourth satellite, to be used as a spare. The spare was pressed into service to replace the first PAS-3 spacecraft, which was lost during a launch vehicle failure. The MEASAT system will provide the first direct-to-user (DTU) service in Malaysia, as well as general communications services in an area reaching from India to Hawaii and from Japan to East Australia. Among DTU services are television and educational programs beamed to small (50-cm) home antennas. General regional communications services include telephony, television, data transmission, and business networks. Binariang is the first cellular operator in Malaysia to offer fully digital services.
Geostationary OrbitThe XTE (X-Ray Timing Explorer), renamed on orbit RXTE (Rossi X-Ray Timing Explorer) mission has the primary objective to study the temporal and broad-band spectral phenomena associated with stellar and galactic systems containing compact objects in the energy range 2--200 keV and in time scales from microseconds to years.
Low Earth OrbitEchoStar 1 is an American geostationary communications spacecraft that was launched by a CZ-2E with EPKM upper stage rocket from Xichang Center in Sichuan province, PRC. The 3288 kg spacecraft carries 16 Ku-band transponders to enable direct broadcast communications and television channels through 0.5 meter dishes on the ground in the American continents.
Geostationary OrbitIRS 1C and 1D (Indian Remote Sensing Satellite) were the second version of the series of indigenous state-of-art remote sensing satellites. Skipper was an international project initiated by BMDO to measure the bow-shock UV emissions from reentering bodies at different speeds and heights.
Low Earth OrbitUS-PM (Upravlenniye Sputnik Passivny Modifikirovanny) (also reported as US-PU) was a solar powered improved EORSAT (Electronic Ocean Reconnaissance Satellite). It used an passive ELINT devices to track naval vessels from space by registering their electronic emmissions.
