The goal of the NASA Space Geodesy Project (SGP) is to build, deploy, and operate a next generation NASA Space Geodetic Network of integrated, multi-technique next generation space geodetic observing systems. This new NSGN will serve as NASA’s contribution to a global network designed to produce data required to maintain the Terrestrial Reference Frame and provide other data necessary for fully realizing the measurement potential of the current and coming generation of Earth Observing spacecraft.
SGP is part of the Earth Science Decadal and the National Research Council study "Precise Geodetic Infrastructure." It is a Goddard/JPL partnership with participation from the Smithsonian Astrophysical Observatory and the University of Maryland.
