摘　　要：随着GPS定位技术的开发和应用,RTK在工程测量中得到了很好的推广。在大地测量中,三维直角坐标转换扮演着重要的角色,如WGS-84坐标系与西安80坐标系之间的坐标转换,或者地方坐标系之间的转换。结合某市开发区一系列静态GPS点进行实验,研究Leica系列GPS-RTK在工程测量应用转换参数3种求定方法,并对平面和高程精度进行分析,选择最高效、最精确的方法,从而在一定程度上减少工作量、降低生产成本,更好地为我国的工程建设服务。Along with development and application of GPS positioning technique, RTK technology obtaines a very good promotion in engineering surveying. 3D rectangular coordinate transformation plays an important role in geodetic survey, e. g. the coordinate transformation between WGS-84 and Xi＇an 80 or between two different local coordinate systems. Combined with a series of GPS points in some development zone analysis is made on the three methods of solving coordinate transformation parameters of Leica GPSy RTK in engineering surveying, as well as on the location accuracy of plane and height, by selecting the best method to cut back on workload, reduce production cost and fit the engineering construction.
