The GOP DORIS analysis center: data processing and innovation strategy

Popis výsledku v původním jazyce

Geodesy Observatory Pecný (GOP) analysis center is one of the International DORIS Service (IDS) analysis centers. GOP fully contributed to the IDS combination of the ITRF2020, reaching various improvements in comparison to the ITRF2014 reprocessing. GOP also participates in the IDS operational solutions. A major progress has been reached in the data preprocessing strategy, South Atlantic Anomaly mitigation and satellite orbit & attitude modeling. improvements in the internal strategy together with an updating of external models to the recent standards resulted in the significant improvement in the station positioning including of the stability of the transformation parameter time series. Also the pole coordinates estimation accuracy has been increased. This improvement is illustrated comparing the statistics of GOP contributions to the IDS combination for the ITRF2014 and ITRF2020. Important improvement in the GOP processing capability is the adaption of the software tools to the RINEX data processing, getting closer to raw DORIS measurement. In addition, we present initial results of the data processing and a modeling verification for the post-ITRF2020 data from the DORIS satellites Sentinel-6A, HY-2C and HY-2D.
