Abstract

The three INMs involved in the JRP e-MASS project operate three different absolute gravimeters, which rely on three different measurement methods. METAS operates a commercial FG5 gravimeter, INRIM has been developing his own ballistic symmetrical rise-and-fall gravimeter IMGC-2 and LNE-SYRTE develops a cold atom gravimeter. These gravimeters are briefly described in this paper and their differences and performances are discussed. The results of a comparison performed at the LNE laboratory will be presented.
