GipsyX – GNSS Software

GipsyX is a high-precision GNSS data analysis software developed and maintained by NASA’s Jet Propulsion Laboratory (JPL), replacing the previous GIPSY-OASIS system. It processes data from GPS, GLONASS, Galileo, Beidou, DORIS, and SLR to provide centimeter-level positioning, timing, and precise orbit determination for terrestrial stations, aircraft, and satellites, including low-Earth orbiters and GNSS constellations. GipsyX supports geodetic and Earth science applications such as monitoring Earth deformation, plate tectonics, ice flow, reference frames, and Earth rotation parameters. It offers a single high-level interface, ambiguity resolution, and integrates with JPL orbit and clock products, serving hundreds of research and educational users worldwide.
