Abstract
Celestial navigation is a kind of autonomous navigation method for satellites especially the high-earth satellite. The basic principle of it is using the measurement of celestial bodies to calculate the position of satellite. This paper presents a new celestial navigation method for geosychronous(GEO) satellite which first calculate the position using the celestial measurement through the geometry method and then reestimate the original position detennination results by Extended Kalman filter(EKF) to get a better navigation result. At last the validity and effectiveness based on the observability analysis of this method are demonstrated by a simulation result.
