Thus, the 4 IDS Analysis Centers have re-analyzed all the DORIS observations from the fifteen DORIS satellites from January 1993 to December 2020.0. The primary objective of this study is to analyze the DORIS contribution to ITRF2020 in terms of (1) geocenter and scale solutions; (2) station positions and week-to-week repeatability; (3) Earth orientation parameters; (4) a cumulative position and velocity solution. Comparisons with the IDS contribution to ITRF2014 will address the benefits of the new antenna models, new models, including improved methods to handle non-conservative force model error on the Jason satellites, as well as the addition of data (compared to ITRF2014) from the latest DORIS missions (e.g. Jason-3, Sentinel-3A/B) in the IDS combination. 000196434 655_4 $$aanotace 000196434 7730_ $$92021 000196434 8564_ $$uhttps://meetingorganizer.copernicus.org/EGU21/EGU21-2315.html 000196434 85642 $$ahttps://www.isvavai.cz/riv?s=rozsirene-vyhledavani&ss=detail&n=1&h=RIV%2F00025615%3A_____%2F21%3AN0000059%21RIV22-MSM-00025615 000196434 910__ $$aABC039 000196434 985__ $$astepanek 000196434 985__ $$ariv 000196434 985__ $$autvar24 000196434 985__ $$aanotace
