A scheme of estimating the flight attitude of a rolling missile based on square root-unscented Kalman filter(SR-UKF) was proposed. To get the attitude of an experimental missile, a telemetry scheme based on two-axis liquid-droved rate gyroscope was studied. The telemetric data was processed by SR-UKF to reconstruct the attitude of missile. Aiming at the non-linearity of dynamic model of rolling missile, the scheme of attitude estimation algorithm based on square root-unscented Kaman filter (SR-UKF) was used to eliminate the errors caused by linearization of extended Kalman filter (EKF). Using the dynamic attitude model of low rate rolling missile, a group of iterative filter equations based on SR-UKF were educed. The estimation result obtained form the proposed algorithm was compared with EKF and UKF ones, which showed the effectiveness of the proposed algorithm.
