A self-position measuring device includes an information generator, a position extractor, and a navigation method selector. The information generator generates estimated information that is expected to be obtained when at least one of the ground information and the celestial information is obtained, at each of multiple reference points generated on the basis of measured inertial navigation position. The position extractor checks at least the one of the ground information and the celestial information against the estimated information at each of the multiple reference points and extracts a position of a specific reference point corresponding to specific estimated information with a highest matching degree. The navigation method selector selects, on the basis of the specific reference point, a navigation method with less navigational error as a navigation method for measuring the self-position.
