Source: 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

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.
