Event: 2014 Ocean Surface Topography Science Team Meeting

Session: Precision Orbit Determination

Presentation type: Type Oral

The reference OSTM/Jason-2 satellite has been in orbit for more than 6 years (since June 2008) and ensures the continuity of the precise climate record of the Jason-1 mission that stopped last summer after more than 11 years in orbit.
The whole set of Jason-1 and Jason-2 cycles has lately been reprocessed with a new GDR-E* (future version E?) Precision Orbit Determination standards, including especially: geocenter motion modeling, a new mean geopotential model (EIGEN-GRGS.RL03.MEAN-FIELD), based on the release 3 of the CNES/GRGS time series of gravity field and accounting for the interannual variability present in the RL03 monthly time series, the updated DTM-2013 thermosphere model, a calibrated semi-empirical solar radiation pressure model and improved parameterization techniques.
This talk will address the issues of accuracy and long-term stability of the Jason-1 and Jason-2 GDR-D/GDR-E* orbit solutions, and give an overview of the performance of all available tracking systems operating on-board the satellites.
