摘要
自由空间光通信将成为未来通信的最佳解决方案之一。首先需要解决实现空间光通信的关键问题是光束的捕获、跟踪和瞄准。该文介绍了自由空间光通信终端机中ATP系统的组成和工作原理,设计了用于ATP系统的精瞄偏转镜、闭环控制器、星上终端二次电源系统,并给出了该系统性能的测试结果。
Free space optical communication is one of the best approaches in future communication. Laser beam＇s acquisition, tracking and pointing is one of the key technologies of free space optical communication. The constitute and work principle of ATP is introduced. The fine pointing tip/tilt mirror, second power supply system, closed loop controller in the satellite is designed, and the test result of the system performance is proposed.
