Geodesy Observatory Pecný (GOP) analysis center is one of the International DORIS Service (IDS) analysis centers. GOP fully contributed to the IDS combination of ITRF2020, reaching various improvements in comparison to the ITRF2014 reprocessing. The time-variable gravity field model and pole sub-daily model were updated to the recent standards. The RINEX data were included as well as the measured attitude for Jason satellites and the attitude event file for TOPEX/Poseidon. A special South Atlantic Anomaly mitigation strategy was applied for SPOT-5 and Jason-3, while Jason-1 data were completely excluded.
The comparison of the application of manufacture-based and measurement -based Alcatel ground antenna phase variations model was performed. The post-fit Doppler observation residual analysis proved a better performance at the measurement-based model, confirming the recent IDS standards.
Besides the ITRF reprocessing and other specific campaigns, GOP deliveries standard operational solutions each 3 months. A study of the relation between the satellite constellation changes and the solution characteristics is presented.
