PROBLEM TO BE SOLVED: To provide an absolute target system improved by combining a star sensor and an optical metrological sensor for formation flight. SOLUTION: The present invention relates to an absolute target system intended to be incorporated in observation satellites. To establish an absolute target system provided with maximum accuracy, the present invention proposes coupling the star sensor 4 to the optical metrological sensors 5N and 5R. Since these two items of equipment are normally already on board the satellites, in particular for formation flight missions, this solution adds no extra weight or cost.
