One Method on Autonomous Navigation Based on Unscented Kalman Filter

摘要：

Through much research into environment characteristic of the fast movement and anomalous celestial bodies figure in autonomous orbit determination of deep-space explorer, an autonomous optical navigation scheme based on Unscented Kalman Filter is 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, which can promote parameter mean and predictive precision, so it can solve the difficulty of autonomous orbit determination. Compared with extended kalman filter, it shows that its performance is better than extended kalman filter based on Minimus Mean Square Error.
