西安80坐标系与WGS-84坐标系转换模型的确定

The Transfer Model between the Xi'an 80 and WGS-84 Coordinate Systems

根据GPS -A、B级网中重合 1980西安坐标系下的 174个三角点成果 ,采用三、四、七参数转换模型 ,完成了我国 80参心系与世界 84地心系转换参数的计算与精度分析。

Based on coinciding 174 triangular points from coordinate system 1980 with GPS-A.B networks, this paper takes 3-,4-,7-, parameter transfer model to accomplish calculation from Xi'an 80 coordinate system to WGS-84 coordinate system. After all, accuracy analysis is discussed in this Paper.
