Comparisons of absolute gravimeters (COOMET.M.G-S1)

Abstract

This report describes the results of the RMO supplementary comparison COOMET.M.G-S1 (also known as bilateral comparison COOMET 634/UA/14). The comparison measurements between the two participants NSC 'IM' (pilot laboratory) and INRIM were started in December 2015 and finished in January 2016.Participants of comparisons were conducted at their national standards the measurements of the free fall acceleration in gravimetric point laboratory of absolute gravimetry of INRIM named INRiM.2. Absolute measurements of gravimetric acceleration were conducted by ballistic gravimeters.The agreement between the two participants is good.Main textTo reach the main text of this paper, click on Final Report.
