Abstract
A star sensor compares predetermined star information stored in a memory and actual star information corresponding to star image signals from an imaging device. A processing device generates an attitude signal corresponding to the attitude of a base with respect to the star when the predetermined and the actual star information substantially coincide. A correcting device corrects the predetermined star information when the predetermined star information and the actual star information are not substantially the same.
