A rapid transfer alignment method for missile MEMS SINS is presented.An error model of velocity+attitude information matching method is constructed,and a discretization way of continuous systems easy for engineering application is proposed.Through flutter maneuvering during the alignment procedure,the azimuth estimation accuracy is improved in the scheme.At the same time,in view of the large bias of MEMS inertial sensor,the residual zero offset of gyro is taken as the stage of filter for real-time estimation and compensation.The alignment precision is improved greatly through real-time feedback correcting of attitude and velocity.The flight test results show that the attitude accuracy is better than 0.15°,azimuth accuracy is better than 0.2°,and alignment time is less than 60 s,which can meet the tactical weapon requirements.
