Abstract�� It was found in experiments that the drift of quartz series MEMS(micro electromechanical system)gyroscopes had good orderliness and periodicity against other series MEMS gyroscopes, especially in short-time and high frequency sampling. In order to improve the precision of the quartz gyroscope and the performance of the system, a precise calibration method was raised by studying each period-s parameters as well as its error transfer coefficients according to error analysis theory. The experiment results not only demonstrate that the precision of the quartz MEMS gyroscopes is improved by the accurately calibrating but also testify that the obtained parameters values are applicable to compensation online in long subsequent time. It is extraordinarily necessary for the quartz series MEMS to process the precise periods calibration.
