OBSERVATION PROCEDURE FOR SWEEP OF A HEAVENLY BODY (T) from a spacecraft (5) behaving A SYSTEM OF OBSERVATION BY SCANNING BY REFERENCE TO A scan axis CHARACTERIZED IN THAT FORMED (16) successively two signals (A, B ) corresponding to the SWEEP IN THE SAME SENSE OF SLIDING MAKING SAME GROUND (BT) is detected (17) IN EACH OF THESE SIGNALS A TRANSITION characteristic (A1, B1) REPRESENTATIVE OF THE SAME ITEM cHARACTERISTIC OF THIS INTAKE EARTH IS COLLECTING (18) THE RELATIVE POSITIONS OF THESE TRANSITIONS IN THESE sIGNALS AND DETERMINED (19) FROM A POSSIBLE GAPS THESE POSITIONS ON A POSSIBLE SPEED ANGLE (W) spacecraft, TNEIENDO INTO ACCOUNT distancing SEPARATING TIME MOMENTS wherein each of these transitions has appeared in such signals.
