Abstract

Gravity measurement is of great importance to the height datum in Antarctica. The absolute gravity measurement was carried out at Great Wall Station, Antarctica, using FG5 absolute gravity instrument. The gravity data was processed with corrections of earth tide, ocean tide, polar motion and the atmosphere, and the RMS is within ± 3 x 10(-8) ms(-2). The vertical and horizontal gravity gradients were measured using 2 La Coaste & Romberg (LCR) gravimeters. The absolute gravity measurement provides the fundamental data for the validation and calibration of the satellite gravity projects such as CHAMP, GRACE and GOCE, and for the high accuracy geo id model.
