指向精度是观测设备的一项重要指标, 指向精度的优劣直接影响到对目标的快速捕获和跟踪。通过建立观测设备的轴系误差模型, 并用恒星标校的方法来对轴系误差进行修正, 进而使指向精度得到了提高。

Pointing accuracy is an important index of the observation equipment, the quality of pointing accuracy directly affects the fast acquisition and tracking of the target. In this paper, the axis error model of observation equipment is established, and the star calibration method is used to correct the axis error, so that the pointing accuracy is improved.
