Advancing airborne gravimetry with quantum technology (AeroQGrav) [PDF]
Gravimetry is becoming increasingly important in various fields of geodesy and the geosciences. For example, it can be used to quantify climate change by measuring changes in mass distribution and can assist in the search for raw material deposits.Airborne gravimetry can be used to close the gap between small scaled ground gravimetry and satellite ...

The recent progress using high-precision terrestrial gravity measurements
地球与行星物理论评, 2022 Compare with the airborne and satellite-borne gravity measurements, terrestrial gravity measurements (TGMs) are closer to the sources of mass change and have relatively higher accuracy. The static anomalies and dynamic changes derived from TGMs have been
