摘要

Celestial navigation is a kind of autonomous navigation for deep space explorer. The basic principles of it is using the extended Kalman filter and the measurement of angle between celestial bodies estimate the position and velocity of explorer. Because these angle measurements can not provide enough information to estimate the position of explorer with a high precision, This paper presents a new method of autonomous navigation which uses both the celestial method and the Doppler measurement due to the relative motion from the Earth based on information fusion. The validity and effectiveness of this method are demonstrated by a simulation result.
