摘　　要：卫星激光测距系统(SLR)的测距值,一般归算到方位轴和俯仰轴的空间交会点(几何旋转中心),其空间坐标的确定是观测数据得以应用的前提。介绍一种GNSS天线的安装方案,该方案克服望远镜体积较大,且形状不规则,几何旋转中心难以接近测量的问题,基于BERNESE计算软件,联合多个IGS站,解算出流动SLR几何旋转中心坐标的观测结果,整体精度优于4 mm。The observations of satellite laser ranging （SLR） is the geometric distance between a reference point within the system （the system ＂origin＂） and satellite, which is the intersect point of the telescope elevation and azimuth axes commonly. The coordination determination of the system origin point is the precondition of the observations application. This study introduces a method for determination of system origin of satellite laser ranging, which overcomes the bulk mass and irregular of the telescope. Combined with some IGS stations during the data processing, the coordinate results and their relative positions are obtained using the Bernese software, and the whole precision is better than 4 mm.
