In order to solve the online calibration problem of missile strapdown inertial navigation system (SINS), velocity and attitude matching method based on H∞ filtering was designed to calibrate the errors of gyroscope and accelerometer online. The effect of time unsynchronized information between SINS and master inertial navigation system (MINS) on H∞ filtering estimation was analyzed, and a new method of time synchronization was proposed. The simulation using airborne test data shows that the free inertial navigation position errors of missile SINS are greatly reduced by 82.6% through online calibration and compensation, the online calibration method can estimate SINS errors effectively.
