摘　　要：激光星间通信是未来通信的最佳解决方案之一,激光束的捕获、瞄准和跟踪技术(APT)是激光星间通信的关键技术。精瞄微定位系统是APT系统的重要组成部分,与粗瞄系统配合执行激光束的捕获、瞄准和跟踪任务。该文介绍了精瞄微定位系统的关键技术,详细阐述了精瞄偏转镜机构、驱动检测技术及控制方法等关键技术的国内外研究现状,指明了系统的发展趋势,对进一步研究微定位系统具有指导意义。Laser communication intersatellite is one of the best approaches in future communications. Laser beam ＇s acquisition, pointing and tracking are key technologies of laser communication intersatellite. Fine pointing micropositioning system is important component of APT system. It cooperates with the coarse pointing system in executing the ATB mission. The key technology of fine pointing micro-positioning system was introduced. The current situation of fine pointing steering mirror mechanism, driving and measuring technology and control method were described. The trend of development of system was disscussed.
