Abstract

In order to reduce guidance error, in this paper, the method of rolling estimation for smart munition by geomagnetic sensor was presented. Three coordinate systems were defined, the system model and measurement model were obtained through missile dynamics characteristics and coordinate transformation. The use of unscented Kalman filter(UKF) solver can avoid the introduction of linearization error and the problem of PF particle degeneration. The simulation results show that missile body's roll angle attitude can be well calculated and the error is in the allowable range, it has higher application value.
