Abstract:
The Micro Inertial Measurement System (MIMS) is important equipment for micro aircraft and robot. The biases calibration of MEMS gyroscopes and accelerometers are an effective way to reduce measurement error. In according to error mathematical model of MIMS, a fast field self-calibration method of MEMS gyroscopes and accelerometers is proposed, using the electrolytic gradienter and magnetic compass. The experiment results show that the method can accurately calibrate the biases error of MIMS, improve inertial measurement precision, and verify the efficiency of the proposed method.
