Abstract

As for attitude measurement of missiles, low-precision gyroscope can not get satisfactory accuracy. For this reason, an integrated attitude measurement method was used to correct output of attitude angle, the state equation of attitude error angle and the error observation linear equations that based on the outputs of three-axis magnetometer were built, an adaptive filtering method was used to estimate error angle optimally and correct the output of attitude angle. The simulation results show that this method suppresses the error caused by gyroscope drift effectively by using the output of magnetometer and improves the accuracy of the attitude solver, satisfying the requirement of longtime attitude measurement.

Key words： magnetometer; gyroscope; adaptive Kalman filtering; integrated attitude measurement
