Abstract: The electrostatic suspension accelerometer is a quasi steady and non gravity precision measurement equipment for spacecraft. In the development of electrostatic suspension accelerometer, the evaluation of the functions and the performances of the accelerometer need to be accomplished by the high voltage suspension. On the ground tests, the theoretical analysis of the   electrostatic suspension accelerometer related issues involved in the high voltage suspension was carried out. The ground suspension principle, a high voltage circuit, chooses the working point, control stability, and the high voltage static electricity effect analysis etc.were given. The system resolution near the 0.1Hz is about 10^-8g/Hz^1/2 on ground test, and can finish the function and related performance tests in the suspension state.The main factors of the direct performance evaluation of the electrostatic suspended accelerometer on ground were obtained, and the related problems were discussed.
