Benefit of enhanced electrostatic and optical accelerometry for future gravimetry missions

Seismic noise effect suppression for the performance testing of high-precision space electrostatic accelerometers using a torsion pendulum with differential configuration

“…Space electrostatic accelerometers are one of the most widely used high-precision accelerometers [1][2][3][4][5][6][7], due to their high sensitivity, stability, and wide frequency response. Researchers from Office National d'Etudes et de Recherches Aerospatiale (ONERA) have developed a series of electrostatic accelerometers for different gravity measurement missions [8][9][10], such as the gravity recovery and climate experiment (GRACE) [11][12][13], the challenging mini-satellite payload (CHAMP) [14] and the gravity field and steady-state ocean circulation explorer (GOCE) missions [15,16].…”
