N2 - This paper was performed to find a practical error calibration method for MIMU to overcome the shortcoming of the traditional way. To study it, first, we simplified the error model of the MIMU. The model contains zero bias, scale factors and installation errors of MEMS accelerometer and MEMS gyro. Then, based on the model, we calibrated the accelerometer in use of a practical six-position testing. And in view of the installation error between the turntable and MIMU used in gyro testing, we found a simple method to calibrate the MEMS gyro. The method only need a turntable with one rotation axis. To check the accuracy of the calibration method, for accelerometer, we compared the tilt angle solved by the accelerometer after calibration with the angle before calibration. And for gyro, we compared the output of the gyro after calibration with before. As a result, this method has strength on high precision, easy operation, low cost and strong versatility.
