In a context of global change and increasing anthropic pressure on the environment,
monitoring the Earth system and its evolution has become one of the key missions of …

Gravimetry is a well-established technique for the determination of sub-surface mass
distribution needed in several fields of geoscience, and various types of gravimeters have …

The research on cold-atom interferometers gathers a large community of about 50 groups
worldwide both in the academic and now in the industrial sectors. The interest in this sub …

We report the direct comparison between the stabilities of two mobile absolute gravimeters
of different technology: the LNE-SYRTE Cold Atom Gravimeter (CAG) and FG5X# 216 of the …

We report on the implementation of ultracold atoms as a source in a state of the art atom
gravimeter. We perform gravity measurements with 10 nm s− 2 statistical uncertainties in a …

A determination of the Planck constant h using the LNE Kibble balance in air was carried out
in the spring of 2017. Substantial improvements since 2014, chiefly related to the mass …

Low noise underground environments offer conditions allowing assessment of ultimate
performance of high sensitivity sensors such as accelerometers, gyrometers …

Developments in atom interferometry have led to atomic inertial sensors with extremely high
sensitivity. Their performances are for the moment limited by the ground vibrations, the …

For the first time, we present a complete, processed compilation of all repeated absolute
gravity (AG) observations in the Fennoscandian postglacial land uplift area and assess their …

Quantum gravimeters are a promising new development allowing for continuous absolute
gravity monitoring while remaining user-friendly and transportable. In this study, we present …
