  • Geos 3 - . Payload: GEOS C. Mass: 341 kg (751 lb). Nation: USA. Agency: NASA Wallops. Class: Astronomy. Type: Solar astronomy satellite. Spacecraft: Geos. USAF Sat Cat: 7734 . COSPAR: 1975-027A. Apogee: 848 km (526 mi). Perigee: 817 km (507 mi). Inclination: 115.0000 deg. Period: 101.60 min. Geodynamics Experimental Ocean Satellite. The mission of GEOS 3 (Geodynamics Experimental Ocean Satellite) was to provide the stepping stone between the National Geodetic Satellite Program (NGSP) and the Earth and Ocean Physics Application Program. It provided data to refine the geodetic and geophysical results of the NGSP and served as a test for new systems. A major achievment was the flight of a radar altimeter. Further mission objectives: intercomparison of tracking systems, investigation of solid-earth dynamic phenomena through precision laser tracking, refinement of orbit determination techniques, determination of interdatum ties and gravity models, and support of the calibration and position determination of NASA Spaceflight Tracking and Data Network (STDN) S-band tracking stations.
