The modification involves the exhaustive enumeration of all possible orbital plane positions in order to improve the method’s reliability. It has been shown that such an approach requires a priori information on the pattern of the celestial body's motion, particularly, whether its motion is direct or retrograde.enorbit determination methodscelestial mechanicsArticle
