OSTM/Jason-2 Orbital Information, 2008 to 2019 - This collection contains Ocean Surface Topography Mission (OSTM)/Jason-2 orbital data. These files are produced by CNES for offline (IGDR, GDR) data production. For GPSP1, intermediate level-1 data files are in "RINEX" format and from the Global Positioning System (GPS) receiver and are used to compute precise GPS orbits for the spacecraft. For TLE: Two Line Element files are used to determine the position and velocity of the satellite. They will be used directly to determine each orbit's equator crossing longitude and time which subsequently are used to support spatial search. For MOE and POE, medium-precision and precision orbital ephemeris files are from the DORIS system. All Orbital Information data were made unrestricted on 15 December, 2008. Other data/products associated with OSTM/Jason-2 are also available, including Level-2 Geophysical Data Records (GDRs), ancillary and auxiliary data files used to generate Level-2 products, quality reports from the near real-time altimetry validation system (NRTAVS) and telemetry data.
