Concept information
Preferred term
Geodetic Earth Orbiting Satellite (GEOS)
Definition
- GEOS (Geodetic Earth Orbiting Satellite) is a NASA spacecraft flown as part of the National Geodetic Satellite Program (NGSP). Instrumentation varied by mission, with the goals of pinpointing observation points (geodetic control stations) in a three-dimensional Earth center-of-mass coordinate system to within 10 m, determining the structure of Earth's gravity field to five parts in 10 million, defining the structure of Earth's irregular gravitational field and refining the locations and strengths of large gravity anomalies, and comparing results of the various systems onboard the spacecraft to determine the most accurate and reliable system.
