昆明CORS观测数据的质量评价与分析

Quality Evaluation and Analysis of Kunming CORS Observation Data

连续运行参考站(Continuously Operating Reference Stations, CORS)系统观测数据的质量直接影响其网络差分定位(Network RTK,NRTK)服务的性能,因此,有必要对其进行评价与分析。本文利用TEQC(Translation Editing and Quality Checking)软件对昆明市卫星定位综合服务系统(简称KMCORS)22个基准站,2015—2020年共计6年的观测数据进行了质量评价,结果表明:KMCORS全部基准站历史观测数据所有评测指标合格,各基准站观测条件良好、数据质量优异,可继续服务于昆明市现代测绘基准体系建设。

The quality of observation data of Continuously Operating Reference Stations(CORS)system directly affects the performance of Network RTK(NRTK)service,so it is necessary to evaluate and analyze it.In this paper,the TEQC(Translation,Editing,and Quality Checking)software is used to evaluate the quality of the observation data of 22 reference stations of Kunming Continuously Operating Reference Stations(KMCORS)from 2015 to 2020 for a total of 6 years.The results show that all historical observation data of KMCORS reference stations are qualified in all evaluation indicators,and the observation conditions of each reference station are good and the data quality is excellent.It can continue to serve the construction of modern surveying and mapping reference system in Kunming.
