Abstract:

Regarding the state estimation problem of spacecraft in deep space detection mission, considering that the coordinate system transformation matrix used by the autonomous navigation system based on optical cameras in establishing observation equations contains measurement noise introduced by star sensors, which is coupled with the measurement state and belongs to multiplicative noise, a model of an optical autonomous navigation system with multiplicative noise is established. In response to the problem of increased estimation error in traditional filters that are only suitable for handling additive noise when there is multiplicative noise in the system, the multiplicative noise matrix is introduced into the recursive formula of the Gaussian filtering algorithm for derivation, and combined with the numerical integration method of the mixed-order spherical simplex-radial cubature Kalman filter (MSSRCKF), a mixed-order cubature multiplicative Kalman filter (MC-MKF) is proposed. This filter can process Gaussian and non-Gaussian multiplicative noise introduced into the observation equation by star sensors, improving the estimation accuracy of the filter without increasing computational complexity. Finally, MC-MKF is applied to the autonomous navigation system model and compared with MSSRCKF for analysis. The simulation results show that when there is multiplicative noise in the system, the estimation accuracy of MC-MKF is significantly better than MSSRCKF, and the computational complexity is basically the same as MSSRCKF.
