摘　　要：由于MEMS器件的特殊性,在使用前必须进行标定。在MEMS器件误差数学模型的基础上,根据MEMS微惯性组合的十二位置标定方法,标定MIMU加速度计和陀螺仪的零偏稳定性和安装误差角,并将该方法应用于某MIMU的实验室标定中,验证了该标定方法的可行性。根据实验结果,对加速度计和陀螺仪的输出进行快速补偿,能进一步提高MIMU的姿态解算和导航精度。The MEMS devices must be calibrated before use because of its particularity. In order to calibrate MIMU accelerom- eter,gyroscope bias stability and angular misalignment, a calibration method for MIMU based on the error mathematical models of MIMU was designed. And this method was applied to a MIMU laboratory calibration,which verified the feasibility of the calibration method. According to the experimental results, making fast compensation for the accelerometer and the output of gyro can further improve the accuracy of MIMU attitude solution and navigation .
