Abstract

In SLR system, the pointing precision of telescope significantly influences the tracking efficiency. Compensating the pointing precision commonly uses mathematical models to fit the error of the telescope pointing which are restricted by the quantity and visibility of the stars conditions. To avoid these limitations, this paper proposes a new method to utilize SLR tracking data to fit the deviation between the observed data and predictions. It takes the data density into consideration, and makes use of the residual analysis to aid the model-fitting. We will utilize the observed data of Changchun station to calibrate the pointing precision of our telescope in time.
