摘　　要：提出了一套完整的CORS系统基准网稳定性分析的方法和流程,并通过武汉市CORS系统基准网数据进行了验证。结果表明,该方法可行,CORS系统连续高精度观测数据为地理空间框架的形变分析提供了先进、高效的手段和方法。This paper proposes an appropriate strategies for GPS data processing and deformation analysis of CORS network data,which is proved practical and can reflect the stability of CORS network correctly through the dataset from Wuhan CORS network..Results show that the methodology of deformation analysis and data processing based on the regional CORS network data is feasible and effective.It concludes that high-precision continuous tracking data from CORS is a very valuable asset and can provide a technically advanced and cost-effective geoscientific infrastructure for deformation monitoring analysis.
