GIPSY-OASIS, or GIPSY, is the GNSS-Inferred Positioning System and Orbit Analysis Simulation Software package. GIPSY is developed by the Jet Propulsion Laboratory (JPL), and maintained by the Near Earth Tracking Applications and Systems groups.
Features:
- Analysis of data from Global Navigation and Satellite Systems (GNSS):
- Global Positioning System (GPS)
- Russian GLONASS
- French DORIS
- Satellite Laser Ranging (SLR) system
- Precise centimeter-level GNSS-based positioning and timing:
- Space platforms, including low-Earth orbiters and GNSS constellations
- Airplanes
- Terrestrial (ground) stations, static or moving
- Time transfer
- Single high-level user interface supports majority of precise positioning applications
- Single-receiver ambiguity resolution using JPL's GPS orbit and clock products
- Documentation accompanying software modules, and online help
- Training at annual GIPSY user group classes, and online
- Hundreds of research and educational users in more than 20 countries
- Builds on more than 25 years of JPL experience with GPS data analysis
Applications:
- Terrestrial positioning for geophysical research:
- Earth deformation, plate tectonics
- GNSS Networks (e.g. PBO and SCIGN)
- Ice flow
- Climate studies through observation of troposphere and ionosphere
- Reference frame (geocenter and scale) and Earth rotation parameters
- Airplane positioning
- Precise orbit determination
- Low-Earth orbiters: Topex/Poseidon, Jason-1, Jason-2/OSTM, GRACE, Champ, SAC-C, COSMIC, Space Shuttle (e.g. SRTM), Commercial Satellites
- GNSS constellations including GPS and GLONASS
