Abstract: Airborne space laser communication is characterized by high speed, anti-electromagnetic interference, security and easy assignment. It has been applied in the areas of integrated space-ground communication, networking communication, military communication, reliable communication in anti-electromagnetic environment. The characteristics of airborne laser communication and Y-12 plane are analyzed for aligning the communication optical-axis on airborne platform. Two-stage tracking technology is used to design an airborne pointing, acquisition and tracking (PAT) system for laser communication , which consists of coarse and fine tracking units. The long distance communication experiment of the system carried by Y-12 planes is accomplished. The experiment proves the tracking performance and adaptability of the PAT system.

Key words: communication technology, laser communication, airborne platform, pointing, acquisition and tracking
