摘要
指向精度是影响卫星激光测距经纬仪盲跟和白天测星的重要因素，而恒星标校法可以提高卫星激光测距经纬仪的指向精度，从而满足观测的需要。文中给出了一种利用观测恒星标校卫星激光测距经纬仪指向精度的方法。首先建立了影响经纬仪指向精度的状态参数模型，然后通过选择一定数量的恒星进行观测，确定出该模型的状态参数。最后给出了利用这种方法标校长春人卫站卫星激光测距经纬仪指向精度的结果。
The pointing precision of the satellite laser ranging theodolite is a key factor, which affects the blind-tracking and daytime observation. It can be improved by observing the stars and thus meet the observation demands. A method of calibrating the pointing precision of the laser ranging theodolite by observing the stars is described in this paper. Firstly, the model of state parameters is established, which will affect the pointing precision of theodolite. And then, the state parameters are obtained via choosing and observing some stars. Finally, The calibrating result of laser ranging theodolite in Changchun Observatory is also presented in this paper.
