The ABRIXAS (A Broadband Imaging X-Ray All-Sky Survey) small satellite (A BRoadband Imaging X-ray All-sky Survey Satellite) was designed to perform the first complete survey of the sky with an imaging telescope in the X-ray energy range from 0.5 to 10 keV. MegSat 0 was the first MegSat communications satellite.
Low Earth OrbitLandsat 7 continued the long-term Earth observation Landsat program begun in 1972. Landsat 7 was a joint project between NASA, NOAA, and the US Geological Survey to obtain continuous high-resolution imagary of the earth's surface for environmental monitoring, disaster assessment, land use and regional planning, cartography, range management, oil and mineral exploration.
Low Earth 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 W satellites are designed to provide telecommunications services primarily over Europe (Eutelsat W2, W3 and W5) and communication services over Russia and Africa (W4). W2, W3 and W5 are designed to offer 24 transponders at saturation and W4 is designed to provide 31 transponders at saturation. The W satellites have a minimum operational lifetime of 12 years. The spacecraft are based on the Spacebus-3000B2 platform.
