In order to reduce acquisition and alignment time of wireless laser communication
fastly build laser communication link
global positioning system( GPS) technology is applied in initial pointing of wireless laser communication. Azimuth angle and pitch angles is obtained by calculating GPS positional information with coordinate transform matrix after laser communication terminal both receive GPS positional information and send to opposite terminal
calculate rotation error angle needed to adjust according to the calculated angles and the attitude information. By controlling rotation of two-dimensional turntable to realize fast pointing with certain precision.Outfeild experimental result have comfirms that GPS-aided pointing system by controlling the turntable error within 4. 05°can realize fast acquisition of wireless laser communication links and alignment and has high precision
and validity and practicability of this system is verified.
