摘　　要：　提供了一种以飞行器为搭载平台的精密光电跟踪系统引导精度的分析方法,以两类引导设备为例,从经典误差分析方法出发,分析了引导精度的主要影响因素,包括引导设备的测量误差、空中平台的姿态测量误差及数据传输延迟等,并指出其关键影响因素是引导设备的测量误差,可通过合理设计飞行航路避开最大误差区域或更换高精度引导设备两种途径有效减小引导误差。This paper provided a method of analyzing the orientation error of precise airborne electro-optical tracking system. Taking two types of guiding equipment as example, the authors specified the main affecting factors for the precision, including measurement error of the guiding equipments, attitude measurement error of the platform and data transfer delay. The critical factor for precision was measurement error of the guiding equipments. Guidance precision could be improved via choosing proper flight routes, or using other guiding systems with better precision.
