PURPOSE:To make smaller and thinner the system in the folding-up condition by dividing respective mirror surface parts into three positions, storing to the rocket in the condition folded-up to the U-shape when the artificial satellite is launched, and developing so that the parts may go to parabolic mirror surfaces after launching. CONSTITUTION:A main reflection mirror 13 is stored at the upper part of a launching rocket in the condition fitted through a hinge device 20 to a tower 12 of an artificial satellite 11 beforehand. By the command from a ground station, etc., at the processes to launch and go around on the orbit, the main reflection mirror 13 folded up to the U-shape so as to surround the tower 12 is released from the first holding device 17, both mirror surface parts B are rotated almost to 90 deg. in the direction of an arrow with a rotating supporting shaft 15a as a supporting point, and developed up to the position to form the parabolic surface together with a mirror surface part A. Next, after the time is late a little, the second holding device of the third hinge device 20 is operated, and the main reflecting mirror 13 is developed from the tower 12. Thus, the parabolic antenna with a large area can be loaded into the rocket body.
