摘　　要：全面介绍了南宁市城市高精度三维GPS控制网的概况,然后讨论了利GAMIT/GLOBK软件处理控制网的基线处理方案和网平差方案,计算出各个测站在ITRF2005框架下的三维直角坐标,得出南宁市三维GPS控制网不论从布网,还是精度上均达到甚至优于国家B级GPS网的结论。The high-precision three-dimensional GPS network in Nanning is firstly introduced and then the baseline processing method and network adjustment program using the GAMIT/GLOBK software are discussed in the paper.The three-dimensional Cartesian coordinates under ITRF2005 are obtained by the software.And the conclusion is that three-dimensional GPS control network in Nanning,whether from the distribution of the network,or accuracy are achieved even better than the national B-level GPS Network conclusions.
