针对光电探测设备恒星校正过程中的时效性问题，本文分析了产生时效性的原因以及在时效性存在的情况下，人们期待的两种方式。在此基础上，提出了基于加权最小二乘法拟合求解算法。算法能够实现两个方面的功能：提高了在局部区域内校正的精度；提高了在实时引导使用过程中的引导精度。本文依据两种情况，采用外场试验数据进行了仿真，验证了算法的可行性和有效性。

Due to the changes of environment and the axes of optoelectronic tracking system during the pointing calibration by stars along with the time, people cannot get a very precise result all the time. The problem is considered and the algorithm based on WLMS is introduced to meet the needs of two types. One is to get precise calibration result in a small area of the sky. And the other is to get the precise calibration in real time guiding. Two simulations are introduced to verify the feasibility and validity of the algorithm by using the data gotten from the field.
