Ocean Surface Topography Mission (OSTM) /Jason-2: Orbital Information (NODC Accession 0044985)

Metadata Updated: February 27, 2019

This accession contains the descriptions for the OSTM/Jason-2 orbital information, which is served through the NOAA/NESDIS Comprehensive Large Array-data Stewardship System (CLASS): http://www.class.noaa.gov

OSTM/Jason-2 is a follow-on mission to Jason-1, which takes over and continues the TOPEX/Poseidon and Jason-1 missions. OSTM/Jason-2 involves Centre National d'Etudes Spatiales (CNES), NASA and 2 new partners: the European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT) and NOAA in order to 1) ensure continuity of high quality measurements for ocean science, and 2) provide operational products for assimilation and forecasting applications. OSTM/Jason-2 was launched on 20 June 2008 and reached its nominal repetitive orbit on 4 July 2008. The start of cycle 1 occurred on 12 July 2008.

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. 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 are from the DORIS system. All members of the Orbital Information family were made unrestricted on 15 December, 2008.

Other data/products associated with OSTM/Jason-2 are also provided through CLASS. They are: 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. The descriptions of these data products can also be accessed in other accessions at NODC.
