Abstract. Quantum gravimeters are a promising new development allowing for continuous absolute gravity monitoring while remaining user-friendly and transportable. In this study, we present experiments carried out to assess the capacity of AQG#B01 in view future deployment as field gravimeter hydrogeophysical applications. The is version follow-up AQG#A01 portable quantum developed by French sen...

Context. The free core nutation (FCN) can be observed by its associated resonance effects on the forced nutations of the Earth’s figure axis, as observed by very long baseline interferometry (VLBI), or on the diurnal tidal waves, retrieved from the time-varying surface gravity recorded by superconducting gravimeters (SG). Aims. In this paper, we study the sensitivity of both techniques to the F...

Total sea level changes from space radar altimetry are mainly decomposed into two contributions of mass addition and volume expansion oceans, measured by GRACE gravimeter Argo float array, respectively. However, the averages altimetry, mass, steric have been usually examined over respective data domains, which different to one another. Errors arise this area inconsistency is rarely discussed in...

A single-seed, module-based compact laser system is demonstrated on a transportable $^{87}\text{Rb}$-based high-precision atomic gravimeter. All the required frequencies for atom interferometry are provided by free-space acousto-optic modulators (AOMs) and resonant electro-optic phase (EOMs). The optical phase-locked loop between two paths derived from same provides an easy frequency manipulati...
