Data DescriptionOSTM/Jason-2: Orbital Information - This collection of data contains OSTM/Jason-2 Orbital Information. These data are archived at the National Oceanographic Data Center (NODC) as accession 0044985 (http://www.nodc.noaa.gov/cgi-bin/search/prod/accessionsView.pl/details/44985). The data are distributed through the NOAA/NESDIS Comprehensive Large Array-data Stewardship System (CLASS, http://www.class.noaa.gov). For GPSP1: Intermediate Level-1 data files in "RINEX" format, from the Global Positioning System receiver. Used to compute precise GPS orbits for the spacecraft. For TLE: Two Line Element Files used to determine the position and velocity of the satellite. Within CLASS, 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 from the DORIS system. Produced by CNES for offline (IGDR, GDR) data production. OSTM/JASON-2 is a follow-on mission continuing the TOPEX/Poseidon and Jason-1, and is designed to ensure continuity of high quality measurements for ocean science and to provide operational products for assimilation and forecasting applications. The Jason-2 satellite was launched on 20 June 2008 and reached its nominal repetitive orbit on 4 July 2008.
