摘要
根据大连市C级GPS网中的25个重合三角点成果(1980西安坐标系与WGS-84坐标),采用四、七参数转换模型,完成了我国1980参心系与世界84地心系转换参数的计算与精度分析。
Based on the results of 25 triangular control points in Xi＇an 1980 coordinate system which also within the GPS control network of order C of Dalian city, this paper accomplished the calculation and accuracy analysis from Xi＇an 1980 coordinate system to WGS-84 coordinate system using 4 parameters and 7 parameters conversion model.
