摘要

(57) Abstract This invention regards the identification method of the star. This method selects the star which is detected from midst of the star which is perceived with the sensor; 2 stars each which are detected are designated as group (doublet); The possibility of existing in range of vision of the sensor is highest (promising), selects the all or part of the doublet in the star catalog, form set D with these promising doublets and those stars; Is designated as the star and the opposite which the star of set D are detected; And it consists of the fact that portion or all of group (couple) of the star which is made opposite is supplied to the processing system. This method making use of the class dividing and this class dividing which the star of set D integrates at least, decreases the number of stars which is made opposite, and/or does anti- formation, and/or includes the process which selects the couple which is made opposite at least. It can apply to the attitude determination of the especially aircraft or the submarine this invention.
