摘要

We report a comparison between two absolute gravimeters: the LNE-SYRTE coldatoms gravimeter and FG5#220 of Leibniz Universit\"at of Hannover. They rely ondifferent principles of operation: atomic and optical interferometry. Both aremovable which enabled them to participated to the last International Comparisonof Absolute Gravimeters (ICAG'09) at BIPM. Immediately after, their bilateralcomparison took place in the LNE watt balance laboratory and showed anagreement of 4.3 +/- 6.4 {\mu}Gal.
