Tracking Precision Detection Research On Airborne Laser Transciever

In the information age, space laser communication technology has been increasingly applied to all areas of society for its own merits. laser communication on Aircraft-ground or aircraft-satellites stands as an important component in space laser communication link , and has been developed much, its communication relys on Airborne Laser Transciever. APT system's tracking precision of Airborne Laser Transciever impact its communication capabilities directly. The issue research on tracking precision detection of Airborne Laser Transciever on the purpose of assessing APT system's tracking capabilities of Airborne Laser Transciever, further more it can provide a reliable data for improving the tracking precision.From introducing Space Laser Communication APT System, The paper analyses that in order to maintain a good communication link , it's important to real-time track dynamic light. After compared to other tracking precision detection methods, I put forward two plans: one is using high-precision CCD camera to receive the sign-light of Airborne Laser Transciever, and the other is using the high-precision CCD camera to receive sign-light of target light, which reflect from Airborne Laser Transciever by a reflector, the two programs are different in realization process, but similar in principle. To verify the two plans, the paper established a set of indoor tracking precision detection system, including the Target Light System, the Target Trajectory Simulator, Flight Simulation Device. We carried out a number of experiments By using the detection system, and did experimental data analysis, it verifed the way to detect tracking precision in this paper is feasible.
