Abstract
Normally free-space laser communication system uses the narrow transmission laser beam. It is important to align the laser beams between two laser communication terminals. We developed the automatic alignment system used in the free-space laser communication system. The alignment system adopts GPS (Global Positioning System), the GPS makes the alignment automatic for initial alignment, to use the signal power received or the signal of CCD camera achieves the fine alignment. The principles and configuration frame of the automatic alignment system are discussed in detail.
