With the rapid development of space laser communication technology, it is possible to realize mass data transmission between satellites in low orbit. Micro-nano satellite is the first choice of low orbit communication satellite because of its lightweight, small size and low cost. Laser scanning technology is a kind of technology that can accurately control the direction of laser beam. It has been widely used in the field of space laser communication. In this paper, after analyzing the technical requirements of the scanning mirror with APT system for microsatellite, a kind of miniature scanning mirror is selected to realize the accurate pointing of the beam.
