摘要：
This paper deduces the MIMU miscalibration model from actual installation relation to meet IMU product industry-applied needs. Through analysis and simplification it obtains a linearized model using the least-square method. The simplified linearized model is used to align IMU. Also the parameters' error analysis is conducted for further analysis of the calibration result. Finally, simulations are performed to test the algorithm, which indicates that this algorithm can perform the IMU calibration on high-accuracy level.
