Abstract

Abstract: Upon the demands of high accuracy, high reliability and real time for interplanetary navigation system, an autonomous navigation method for the approach phase is proposed, which relies on the onorbit fusion of optical and radio measurements. To choose appropriate optical measurements and radio measurements for on-orbit fusion, the paper, using a linear covariance analysis and an error analysis method based on B-plane parameters, analyzes various autonomous navigation schemes fusing different optical and radio measurements. The result shows that the proposed autonomous navigation method can effectively improve the navigation accuracy. We also give some principles for reasonable selection of optical measurements. Finally, the presented analysis method is verified by the Monte Carlo target practice based simulation.

Key words: autonomous navigation, linear covariance analysis, B-plane parameters, information fusion
