| 摘 要： | 目前我国测量基准应用最多的是54北京坐标系和80西安坐标系,而这2个坐标系同属于参心坐标系,在实际应用和科研方面都有其局限性。基于对2000坐标系转换的四参数模型进行研究,重点描述从80坐标系到2000坐标系转换的过程及要求,通过对实验数据的精度分析,得出采用这种模型转换的可行性方案,为大地测量坐标系的建设作参考。

| Abstract: | At present our country measurement datum is the largest 54 application Beijing coordinate system and 80 Xi＇an coordinate system, and the two coordinate systems belong to participation in practical application heart coor- dinate system, and scientific research has its limitations. Based on the transformation model research, 2000 coordi- nate system from 80 coordinate system described emphatically from the changeover to 2,000 coordinate system and the request. Through experiment data accuracy analysis by this model, it is concluded that the feasibility of geodet- ic coordinate system plan, and this provides some reference for the construction. |
