We have processed all DORIS data available from 1993 to the end of 2020 for our contribution to the ITRF2020 realization. For that, we adopted the last standards and models recommended by IERS and IDS. We now use body and solar array quaternions for Jason-2 and Jason-3 satellites. We apply a SAA mitigation strategy for Spot-5, Jason series and Sentinel-3A&3B satellites. We have just added the satellite Sentinel-6A to our processing chain. A Precise Orbit Determination (POD) status for DORIS satellites by taking into account all these improvements will be presented. The DORIS scale factor and geocenter is the combination of each single DORIS satellite solutions. We will analyze the scale factor and geocenter of single satellite solutions in order to try to explain the different signatures observed in our solutions.
