Comparisons of absolute gravimeters are essential for the ITGRF to guarantee the traceability and compatibility of observations with AGs. The Regional Comparison of Absolute Gravimeters WET-CAG2021, organized as an Additional Comparison beyond the scope of the CIPM MRA, was held in Germany at the Geodetic Observatory Wettzell (GOW) of the German Federal Agency for Cartography and Geodesy (BKG) in autumn of 2021. The comparison results were calculated by two processing strategies. We present and compare the result of these stategies, together with analysis of gravimeter's deviations from reference values. 000197125 6112_ $$aInternational Association of Geodesy Symposia: Gravity, Geoid, and Height Systems 2022$$cAustin$$d2022 000197125 655_4 $$asbornikove prispevky 000197125 7001_ $$aPálinkáš, Vojtech 000197125 7730_ $$92023$$dBerlín:Springer,2022.$$tInternational Association of Geodesy Symposia: Gravity, Geoid, and Height Systems 2022$$x0939-9585 000197125 85642 $$ahttps://www.isvavai.cz/riv?s=rozsirene-vyhledavani&ss=detail&n=0&h=RIV%2F00025615%3A_____%2F23%3AN0000015%21RIV24-MSM-00025615 000197125 910__ $$aABC039 000197125 980__ $$aclanky_vugtk 000197125 985__ $$akosteleckyjakub 000197125 985__ $$aanotace (J) 000197125 985__ $$ariv 000197125 985__ $$autvar24 000197125 985__ $$apalinkas
