Following a 6-month hardware upgrade, the instrument was able to successively improve on its previous performances in terms of stability and sensitivity. It demonstrated a stability on the gradient measurement down to 0.1 Eotvos (0,1 nm/s²/m or 0,01 µGal/m) on two successive 5-days streaks. Sensitivity was also improved by 50%. This is as far as we know the best sensitivity achieved for an industrial quantum differential gravimeter yet.
