To detect a direction of an object from an artificial satellite for controlling a direction of a device.SOLUTION: A capture tracking system comprises: wave acquiring means for acquiring a wave from an object and being mounted on an artificial satellite; drive means for rotating the wave acquiring means for changing an orientation direction of the wave acquiring means; direction calculating means for calculating a direction of the object, from the wave acquired by the wave acquiring means; and control means for, on the basis of a relative orbit motion model of the object to the artificial satellite, a posture rate of the artificial satellite, and a state shift model indicating variation of a direction of the object in a visual field of the wave acquiring means when the drive means rotates the wave acquiring means, calculating a rotation angle of the drive means so that, a magnitude of deviation indicated by an evaluation function value of a magnitude of a deviation between, a visual field center direction of the wave acquiring means and a direction of the object viewed from the wave acquiring means, becomes small as much as possible and operating the drive means by the calculated rotation angle.SELECTED DRAWING: Figure 3
