| Abstract: | Through much research into methods on autonomous orbit determination of deep-space explorer, an autonomous optical navigation scheme based on UD and EKF was proposed to determine the circling orbit state in time, in which star sensor and navigation camera are used in measuring special angles between planetoids and explorer. And the UD algorithm was carried out and the scheme is feasible from the simulation result. |
| Keywords: | autonomous optical navigation orbit determination extended kalman filter UD decomposing |
