N2 - Star-sensor has an excellent capability of providing high accurate attitude, which depends on the accuracy of location to a large extent. At present, star-sensor is restricted by the accuracy of its location information which is normally given by Initial Navigation System, but this location information involves non-ignorable inaccuracy due to the accumulated error. In prior research, star-sensor needs to sense horizon level to do positioning, but this needs cooperation of other equipment or specific maneuvering which diminishes the nature of autonomy and concealment, at the same time, lowers dynamic performances and introduces more integration error. In this paper, a novel method has been proposed to solve the problems above, which needs no auxiliary information from outside. Location gained by this method is an absolute information which will not divergent over time. Above all, Celestial Navigation System can achieve better autonomous navigation capability and higher navigation accuracy by utilizing this method.
