Developed in 2000, the Global Differential GPS (GDGPS) System hosted by NASA's Jet Propulsion Laboratory (JPL) is a complete, highly accurate, and extremely robust real-time Global Navigation Satellite System (GNSS) monitoring and augmentation system that provides full services for GPS, GLONASS, BeiDou, Galileo, QZSS, and NAVIC.

JPL GDGPS data holdings are archived by NASA’s Crustal Dynamics Data Information System (CDDIS).
