Abstract：In this paper, the static stability test and the dynamic stability test are carried out on the six CG gravimeters. The test results show that the CG-6 gravimeters inherits the static stability advantages of the CG-5 gravimeters. The error in the fitting of the static curve into a straight line is less than 3 μGal, and the maximum fitting difference is less than 5 μGal. The dynamic accuracy and dynamic zero drift rate of the CG-6 gravimeters are significantly better than the CG-5 gravimeters.
