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 …

This review covers basic theory and techniques behind the use of ground-based gravimetry
at the Earth's surface. The orientation is toward modern instrumentation, data processing …

The redefinition of the SI unit of mass in terms of a fixed value of the Planck constant has
been made possible by the Kibble balance, previously known as the watt balance. Once the …

Limits on the long-term stability and accuracy of a second generation cold atom gravimeter
are investigated. We demonstrate a measurement protocol based on four interleaved …

We report on a precision measurement of gravitational acceleration using ultracold strontium
atoms confined in an amplitude-modulated vertical optical lattice. An uncertainty Δ g/g≈ 10 …

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 …

Recent developments in quantum technology have resulted in a new generation of sensors
for measuring inertial quantities, such as acceleration and rotation. These sensors can …

We report a comparison between two absolute gravimeters: the LNE-SYRTE cold atom
gravimeter and FG5# 220 of Leibniz Universität of Hannover. They rely on different …

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 …

Lorentz symmetry is one of the pillars of both General Relativity and the Standard Model of
particle physics. Motivated by ideas about quantum gravity, unification theories and …
