The Space Geodesy Project Office manages the operations and development of NASA¹s Space Geodetic Network that is comprised of the four major space geodetic observing systems: Very Long Baseline Interferometry (VLBI), Satellite Laser Ranging (SLR), Global Navigation Satellite System (GNSS), and the Doppler Orbitography and Radio-positioning by Integrated Satellite (DORIS) system. The Space Geodesy Project (SGP) is a collaborative effort between Goddard Space Flight Center, NASA¹s Jet Propulsion Laboratory, and university and other partners. The primary goals of the SGP are to deliver and maintain a high precision Terrestrial Reference Frame (TRF) and provide the data and analysis essential for fully realizing the measurement potential of the current and coming generation of Earth Observing spacecraft.

The SGP is currently developing a prototype next generation geodetic observing station at the Goddard Geophysical and Astronomical Observatory (GGAO) along with the associated analysis systems for the generation and maintenance of a high precision TRF. Concurrent with completion of the prototype development, the SGP will maintain the operations of the existing network and analysis infrastructure, and establish a programmatic structure to enable the transition from the prototype framework to the realization of the full network. Following prototype development, SGP plans to build, deploy and operate integrated, multi-technique next generation space geodetic observing systems and the analysis systems necessary to deliver TRF products.
