大区域求解网络RTK转换参数探讨

主要阐述了利用多基站网络实时动态测量（RTK）技术建立的南宁市连续运行卫星定位服务综合系统，介绍了一种大区域求解网络RTK转换七参数的方法，并应用于网络RTK测量，对测量成果与我院“CGQC2000与参心坐标系七参数转换研究”转换成果进行比较；应用网络RTK测量市区56个不同等级控制点，并应用基于七参数的大区域网络RTK坐标转换参数进行坐标转换，进行了数据处理和精度分析，同时应用于2009年南宁市地形图修补测项目，取得了较好的效果。

Large Area of Transformation Parameters for Solving the Network RTK

Mainly on using multiple base stations network RTK technology of Nanning city of continuous operation of the integrated system of satellite positioning services, introduced a regional solution for network RTK converted seven parameters of the method, compared network RTK surveying and measurement results to ＂CGQC2000＂,and made network RTK surveying urban 56 different grades of handle. The application is based on the seven parameters of large regional network RTK coordinates transformation parameters for coordi- nate conversion, data processing and analysis of precision, while at the same time applied to the 2009 Nanning map patch test project, and achieved good results.
