The GOP Analysis Center: DORIS contribution to ITRF2020
Original language description
The Geodetic Observatory Pecný (GOP) analysis center of the International DORIS Service (IDS) has participated in the ITRF2020 IDS DORIS data reprocessing. This participation followed previous contributions for the ITRF2014 and ITRF2008. The processing standards have changed since the ITRF2014 realization, in particular by switching to data processing based on RINEX observation files, keeping compatibility with the recent operational version of the IERS2010 conventions and with the IDS recommendations. The orbit parametrization and various models have been updated to reach the recent highest standards. The analysis strategy is completely independent of the auxiliary information from the data provider such as quality indicators and center of mass corrections. Several testing campaigns have been performed to optimize the strategy. Jason-1 data have been completely excluded, while SPOT-5 data have fully contributed. A specific strategy for handling the South Atlantic Anomaly was applied for the satellites SPOT-5 and Jason-3. When compared to the GOP solution for ITRF2014, changes in modeling and processing strategy resulted in several significant improvements in the solution statistics and the series of estimated parameters as the stability of the scale and the scattering of the translation series. The analysis of the WRMS of the station position residuals confirmed improvements in particular between mid-2002 and mid-2008 (reduction by more than 1 mm) and after mid-2008 (reduction by about 3 mm). The decrease of the standard deviations in the estimated pole coordinate series reaches 40 percent after adding of Jason-2 in mid-2008.
