摘　　要：CORS系统已成为测绘行业重要的基础设施,向用户提供实时、精准的点位坐标信息,广泛应用于各行业测绘工作,但观测环境对定位精度影响方面的分析工作却很少,本文在不同的观测环境下利用全站仪和网络CORS技术分别进行地物点测量,将其测量结果进行对比,分析外界环境对网络CORS测量精度的影响,得出了一些有益的结论,提出了CORS技术野外作业需注意的一些问题。The CORS system has become an important infrastructure in the surveying and mapping industry,providing users with real-time and accurate point coordinate information,which is widely used in various industries,but the analysis of the impact of the observation environment on positioning accuracy is rare.In this paper,we use the total station and CORS technology to measure the object points in different observation environments,and compare the measurement results.The influence of the external environment on the measurement accuracy by CORS is analyzed,and some benefits are obtained.Some problems that need to be paid attention to in the field work using CORS technology are put forward.
