摘　　要：为了进一步促进智慧城市建设,提供精准可靠的CORS定位数据,本文对已有定位精度检测方法进行深入学习和总结,在此基础上提出基于非参数统计下CORS系统定位精度检测模型,以LNCORS系统数据为基础进行实验分析,验证CORS基准站点周围综合环境与定位外符合精度属于显著弱相关。以此为基础,采用动态已知点法和车载测试方法对省内CORS系统内、外符合精度进行测试分析,结果表明该方法在提高CORS定位精度检测方法的科学性和完整性上具有一定的参考意义。In order to further promote the construction of a smart city and provide accurate and reliable CORS positioning data,this article conducts in-depth study and summary of existing positioning accuracy detection methods.On this basis,a positioning accuracy detection model for the CORS system based on non-parametric statistics is proposed.Based on the LNCORS system data,experimental analysis is conducted to verify that the comprehensive environment around the CORS benchmark site has a significant weak correlation with the positioning external coincidence accuracy.Based on this,the dynamic known point method and vehicle testing methods are used to test and analyze the internal and external coincidence accuracy of the provincial CORS system.The results show that this method has certain reference significance in improving the scientificity and integrity of the CORS positioning accuracy detection method.
