| Abstract: | With the development of our lunar exploration project,the capability of autonomous navigation is in great demand for lunar satellites for limitations of radiometric tracking. A new autonomous navigation method based on celestial and landmark measurements is proposed in this paper. An advanced unscented Kalman filter and corresponding information fusion technique are used to get a better navigation performance and higher reliability. Furthermore,because updated quaternion hardly obeys a unit norm constraint,... |
