Abstract: The MEMS inertial components have some disadvantages such as low-accuracy and big-noise, which can’t used for navigation alone because of accumulated error. In order to solve this problem, a MEMS-gyro array structure design is proposed. After the calibration of the MIMU, the information fusion algorithm based on support degree is used to deal with the data of the MEMS-gyro array. Experiment results show that this structure design and information fusion method can effectively improve the accuracy of the MIMU, which has some engineering application value.
