TBC与GAMIT进行CORS站基线解算的精度分析——以广州CORS基准站数据处理为例

TBC and GAMIT CORS Baseline Solution Precision is Analyzed——GZCORS Reference Station Data Processing

CORS系统作为地理空间框架的重要基础设施之一,其稳定性是确保系统正常运行的关键。根据《卫星定位城市测量技术规范》的要求,需定期对CORS网进行解算。本文以广州CORS网为例,采用天宝TBC软件和美国GAMIT软件对CORS站GPS静态数据进行处理,采用不同的解算模式,讨论两款GPS处理软件在基线解算结果方面的差异,得到一些有益的结论。

COPS system is one of the important infrastructure of geo-spatial framework,its stability is the key to ensure the normal operation of the system. According to＂Technical code for urban surveying using satellite positioning system＂requirements ,the need for regular CORS network solution. Based on the Guangzhou COPS network as an example,for processing GPS static data on CORS station using TBC software and GAMIT software USA Trimble,the numerical solutions are different, the two GPS processing software solution results in the base line differences, some useful conclusions are obtained.
