Autonomous Optical Navigation Method Based on Information Fusion Using Square-root Unscented Kalman Filter
An autonomous optical navigation scheme for cruise phase is presented using the star light data and body edge data which is measured by star sensor and optical navigation camera in this paper. And the relative position for probes is acquired from the star light data and body edge data. Aiming at the non-linearity of state equation and observation equation and we makes a process of SR-UKF (Square-Root Unscented Kalman Filter) based on these work. The real time orbit for probes is determined by using these. The arithmetic integrates square-root and UKF to improve the precise and reliability of the autonomous optical navigation system. The advantage of the arithmetic is showed by the simulation through compared with the EKF.
