Gravitational force and acceleration measurement devises have been in continuous development with the objective to improve the method for realizations of the gravitational acceleration measurand accurately. The accuracy requirements from the field of metrology, geodesy, geophysics and mineral exploration led to these developments. In metrology, knowledge of gravitational acceleration is require...

In March 2015, a ground vehicle gravimetry test was implemented in eastern Changsha to assess the repeatability and accuracy of ground vehicle SINS/GNSS gravimeter-SGA-WZ02. The gravity system developed by NUDT consisted of a Strapdown Inertial Navigation System (SINS), a Global Navigation Satellite System (GNSS) remote station on test vehicle, a GNSS static master station on the ground, and a ...

Absolute gravimeter has played an important role in geophysics, metrology, geological exploration, etc. It is instrument applying laser interferometry or atom to the measurement of gravitational acceleration <i>g</i> (approximately 9.8 m/s<sup>2</sup>). To achieve a high accuracy, vibration correction method often employed reduce influence reference object (a retro-refle...
