Event: 2014 Ocean Surface Topography Science Team Meeting

Session: Precision Orbit Determination

Presentation type: Type Oral

For our contribution to the ITRF2013, we processed 20 years of DORIS data with the available DORIS network. We focus here on the satellites used for the altimetry, TOPEX, ENVISAT, JASON-1, JASON-2, CRYOSAT-2, HY2-A and SARAL. First, we present in this contribution the POD standards used for the re-processing. The CNES/CLS IDS Analysis Center determines the orbits from the beginning of each mission to the end of year 2013. For these satellites the orbits are available in the SP3c format on all over the processing period at the IDS Data Centers (CDDIS and IGN). We show the statistical results such as one per revolution empirical acceleration amplitudes, orbit residuals. We give also some comparisons to the CNES precise orbit used for altimetry.
