一种高精度定位设备光电系统标校方法

摘要

针对外场光电系统测量精度的标校存在的不足等问题，提出了一种基于 GPS 的光电系统测量精度的标校方法。在标校系统组成及标校原理分析基础之上，进行了理论指向和距离的解算推演，并分析了 GPS 定位误差对标校系统精度的影响。该方法能有效地克服场地选择困难和角度范围小等不足，满足光电系统测量精度标校的要求。%For the deficiencies in measurement accuracy of photovoltaic field calibration ,a calibration method of photoe‐lectric system measurement precision based on GPS is proposed .Based on the components of calibration system and analysis of calibration principles ,deduction of theoretical direction and distance is carried out ,and the effect of GPS positioning error on calibration accuracy .It proves that the method can effectively overcome the difficulty of site selection and small angle , meeting the requirement of photoelectric system calibration precision .
