为提高高空、远距离条件下的光测交汇精度，需要对光测数据的系统误差进行精确修正，利用高空飞行器被动段的轨道特性和多测站冗余观测数据，可以进行轨道约束自校准。首先分析了光测数据系统误差模型和坐标转换关系；然后建立了基于轨道约束的光测数据系统误差自校准算法。最后为验证方法的有效性，进行了典型条件下的仿真试验。仿真结果表明，当采用多台光电经纬仪的冗余观测数据进行事后处理时，利用轨道约束自校准技术，可以实现光测数据系统误差的精确自校准。

In order to improve the intersection precision of optical measurement under the conditions of high altitude and far distance, the systematic error of optical measurement data must be accurately corrected, and the unpowered orbit characteristics of high altitude space craft can be used to realize the orbit restrain self-calibration. Firstly, the systematic error model of optical measurement data and the coordinate transition were analyzed. Then, the orbit restrain self-calibration algorithm of optical measurement data was set up. Finally, the simulation test in typical cases was implemented in order to verify the effectiveness of the method. The simulation results show that the systematic error of optical measurement data can be accurately corrected by the technology of orbit restrain self-calibration when the redundant observing data of multiple photoelectric theodolites are used in post data processing.
