A tip-tilt mechanism is one of the key technologies in satellite payloads for meteorology and remote sensing. The same technology is also used for ground telescopes to enhance the image quality. Giant Magellan Telescope is a next generation giant telescope, which contains a tip-tilt secondary mirror. A consortium led by Korea Astronomy and Space science Institute (KASI) is developing a prototype of the tip-tilt secondary mirror. The prototype is a full-size segment of the secondary mirror system, consisted of a dummy mirror, a mirror cell, three axial supports, a lateral support, and a vacuum device. Design, analysis, manufacturing, and assembly have been performed, and system test will be followed. In this paper, development of the prototype is presented and a sample test is shown. The tip-tilt technology will be beneficial to many fields related to precision control.
