广州CORS基准站的稳定性分析与研究

CORS系统作为地理空间框架的重要基础设施，需向用户提供精确的三维定位服务。CORS系统基准网自身的稳定性是确保系统正常运行的关键。本文以广州CORS网为例，简要介绍了基准站网稳定性分析的流程，主要包括：数据整理准备、基线解算、平差计算、稳定性分析等，并最终得到可靠的分析成果。结果表明了该方法的可行性，对后续稳定性分析工作具有一定的指导意义。

Stability analysis of Guangzhou CORS stations

CORS system as an important infrastructure of geo spatial framework, provides accurate three- dimensional positioning service to users. Stability standard of CORS stations is the key to ensure the normal operation of the system. Based on the Guangzhou CORS network as an example, the reference station network stability analysis process is briefly introduced, mainly including： data preparation, baseline solution, the adjustment calculation, stability analysis, and get the final reliable solutions. The results show that the method is feasible and has a certain guidance for further stability analysis.
