Evaluating the Performances of an Operational Absolute Quantum Gravimeter

The Absolute Quantum Gravimeter (AQG) is an industry-grade gravimeter measuring g with laser-cooled atoms, that has been developed by Muquans in close collaboration with RESIF (the French Seismologic and Geodetic Network, [2]) and the LNE-SYRTE laboratory. This paper reports on the evaluation of the first unit of the AQG and in particular on a statistical uncertainty on the measurement of g better than 1.10
