Geodynamics and Experimental Ocean Satellite (GEOS) is the third of the NASA’s geodetic mission program GEOM. It was launched in April 1975 and continued gathering data for more than 3 years, until July 1979. The satellite was designed to detect gravitational anomalies as well as ocean’s mesoscale circulation. Its orbit was non-Sun-synchronous, with an inclination of 115°.
