This system comprises a star catalogue of the universe, a star sensor and means for calculating features on the surface of the star sensor from a signal detected by the star sensor. The calculated features are compared with a table of which the star catalogue was reconstituted so as to easily search the features, thereby determining the attitude of the satellite. | |
