TOPEX/Poseidon, which orbits at an altitude of 1336 kilometers above the earth at a 66 degree inclination, revolves around the planet 127 times every ten days to complete its cycle. The satellite uses radar altimetry to determine sea level measurements within a 4.3 cm accuracy. �The variations in sea suraface height can be used to measure wave heights, sea surface temperatures, and wind speeds. 2) GOES-- � The Geostationary Operational Enviornmental Satellite, GOES, system is a basic element of U.S. weather monitoring and forecast operations. �Spacecraft and ground-based systems work together to accomplish the GOES mission of providing weather imagery and quantitative sounding data that form a continuous and reliable stream of environmental information used for weather forecasting and related services by sensing different wavelengths of radiation emitted and reflected from moisture and other particles in the atmosphere. 3) AVIRIS-- �The Airborne Visible InfraRed Imaging Spectrometer, AVIRIS, main objective is to identify, measure, and monitor constituents of the Earth's surface and atmosphere based on molecular absorption and particle scattering signatures. Research with AVIRIS is dominantly directed towards understanding processes related to the global environment and climate change. 4) ERS-1-- �On 17 July 1991, the European Remote-Sensing Satellite, ERS-1, the first European satellite to carry a radar altimeter, was launched into an 800 kilometer altitude and 98.5 deg inclination orbit. Since launch the satellite has monitored the sea surface almost continuously along with monitoring the Earth's atmosphere. The accuracy of its altimeter range measurements has been estimated to be a little under 5 cm. 5) G.P.S.-- Global Positioning System, GPS, is funded by and controlled by the U. S. Department of Defense (DOD). While there are many thousands of civil users of GPS world-wide, the system was designed for and is operated by the U. S. military. GPS provides specially coded satellite signals that can be processed in a GPS receiver, enabling the receiver to compute position, velocity and time. The nominal GPS Operational Constellation consists of 24 satellites that orbit the earth in 12 hours. There are often more than 24 operational satellites as new ones are launched to replace older satellites. The satellite orbits repeat almost the same ground track (as the earth turns beneath them) once each day. | |||||||||||||||||||||||
