For analyzing the random error coefficients of inertial measurement units(IMU)
the Allan variance method is studied.For large data set processing
a simplified Allan variance algorithm which can both reduce the calculation burden and keep the accuracy of the results is proposed.The proposed algorithm is used to analyze the long-term static data collected from a micro-electro-mechanical systems(MEMS)IMU.Results demonstrate that the proposed simplified Allan variance method can effectively recognize the error coefficients of the IMU.
