The random error of MEMS gyroscope is a key factor affecting the accuracy of inertial navigationwhich restricts the development of inertial navigation.In order to improve the performance of MEMS gyroscope and improve the accuracy of Allan variance identificationthe random drift error of the gyroscope is analyzed by using the improved Allan variance method.On this basisthe random error model of MEMS gyroscope is established by using the time series analysis method.The results show that the method is simple in calculationflexible in modelingand can significantly improve the accuracy of Allan variance calculation and data utilization rate.The time series model is stable and has strong applicability.
