Pre-GRACE era recovery of time-varying DORIS-based mass concentration parameters for TOPEX/Poseidon precise orbit determination.
Event: 2018 IDS Workshop
Session: SESSION III: Precise Orbit Determination
Presentation type: Oral
Local mass anomalies, i.e. mascons, are discussed here to complement to the GRACE-derived time-varying gravity field models used in the standard POD solutions. Relying on multi-missions DORIS measurements, both long-term and seasonal variations are investigated.
In this paper, we present the results of an analysis based on the ‘mascons’ approach to improve the performance of the reprocessed TOPEX/Poseidon (T/P) precise orbits in the last CNES GDR-F standards. The SPOT-2 and SPOT-4 missions, launched in 1990 and 1998, respectively, as well as the T/P DORIS tracking measurements, are used here to leverage these data into the pre-GRACE era (before 2002).
