摘　　要：介绍采用基于IGS连续运行基准站的单点定位的方式求取控制点2000国家大地坐标系的方法。利用GAMIT解算基线,在平差软件中强约束IGS连续运行基准站进行约束平差,得到控制点的2000国家大地坐标系坐标。经过实例检核,该方法可以满足D级GPS控制网起算点的精度要求。This paper briefly described the method to get the CGCS2000 coordinate of control point by point positioning based on IGS Continuously Operating Reference Stations.Calculating the baseline by GAMIT,High Precision Long Baseline Solution Software,and making constrained adjustment by strong constraint IGS Continuously Operating Reference Station in the adjustment software,the CGCS2000 coordinate of control point was getted.Finally,an instance of the data was checked.The method meets requirement of precision of start points of the D-level GPS control network.
