PURPOSE: To satisfy the requirements of a high mirror surface accuracy and light weight for satellite mounting at the same time by adopting the soft construction for an antenna reflection mirror, providing an elastic deformation to the mirror surface and compensating the deformation produced by an external force and heat or the like.
CONSTITUTION: An antenna reflection mirror surface 1, an actuator 2, a back face supporting frame 3 to support the reflecting surface 1, a photodetector for a measuring device to measure optically the three-dimensional position of the reflection mirror shell and a luminescence part 4 of the measuring device are provided. Then the relation of position between the photodetector part 4 and the luminescence part 4' fixed to an artificial satellite main body 5 is indexed by the photodetector part 4 arranged to the antenna reflection mirror and the deviation with the design value is calculated by a measuring operating section 6. Further, the shape of the mirror surface is analyzed by a data processing circuit 7 so as to conduct data processing to return the mirror surface to the shape at the design, an actuator driving circuit 8 transmits a control signal and allows the actuator 2 to move the mirror surface.
