UNAVCO News: The NASA Space Geodesy Project -- An Update
02/24/2018

NASA’s Space Geodesy Project (SGP) was initiated in order to develop and maintain a global network of next-generation space geodetic observing instruments. Core sites around the globe will use three or four of the primary space-geodetic techniques: Very Long Baseline Interferometry (VLBI), Satellite Laser Ranging (SLR), Doppler Orbitography by Radiopositioning Integrated on Satellite (DORIS), and the Global Navigation Satellite System (GNSS). Deployments of these instruments with next-generation measurement capabilities have been underway since 2011.
