在分析国外舰载机传统光学助降系统和雷达全自动盲降系统发展现状的基础上，给出基于舰载光电跟踪技术装备的光电助降系统的组成、配置、技术原理、技术指标，对光电助降系统中光电测量坐标系到甲板坐标系进行转换，对光电助降系统的测量误差和定位误差进行建模，在舰船无摇摆以及纵摇2°周期20s，横摇10°周期15s条件下，结合我国现有技术基础，分析摇摆姿态角误差、距离误差、跟踪测角误差对光电助降系统定位精度的影响并进行仿真实验，给出舰载机距着舰点距离大于1 km和小于1 km时光电助降系统的定位误差。

By analyzing present state of the optoelectronic aid system of carrier landing, the component, configuration, technology principle and technology target of the optoelectronic aid landing system were presented. Combining with the existing technology, the key factors of location precision were analyzed deeply by swaying experiment and simulation. Under the condition of no-swing, pitching of 2°and period of 20s, or rolling of 10°and period of 15s, the location error of the optoelectronic aid landing system was provided when the distance between carrier aircraft and landing site was greater or less than 1 km.
