摘　　要：CORS站观测数据质量直接影响其服务性能。利用TEQC及QCVIEW32对临沂大学CORS站观测数据进行处理,根据观测值有效率、多路径效应、信噪比和电离层延迟误差及电离层延迟变化率等指标评定数据精度,为临沂大学的CORS站建设提供科学依据,对单基站CORS建设提供指导。The quality of the data observed by CORS station directly affects its performance of services. TEQC and QCVIEW32 are used to process the observation data of CORS station of Linyi University, and this paper conducted the quality analysis of the data by the indexes such as data efficiency, multipath effect, signal to noise ratio, ionospheric delay and ionospheric delay change rate, etc., to provide scientific evidence for the construction of CORS station in Linyi University and guidance for the construction of Single base station CORS.
