佘山1.56米望远镜与SLR望远镜旋转不动点的测量

Surveying of Sheshan 1.56 Meters Optical Telescope and SLR Telescope＇s Fixed-rotation Point

佘山1．56米光学望远镜观测站与卫星激光测距（satellite laser ranging，SLR）观测站是进行天文地球动力学研究的重要观测站。应用这些观测站进行空间测量需要这两个观测站在空间的准确坐标。为此重点介绍了1．56米望远镜与SLR望远镜旋转不动点的观测方案和计算方法。归心结果经确认达到厘米精度，能够实施相应的观测任务。

Sheshan 1.56 meters optical telescope and SLR （satellite laser ranging） telescope are important instruments for the astrometry and astro-geodynamic research. Accurate coordinates of these two observations are necessary to such scientific applications as satellite orbit determination, plate motion and so on. In this paper, we emphasize on the presentation of the strategy and processing of the station coordinate determination. At last, we find that the accuracy meets cm level which means that it can come into use in the following applications.
