基于TEQC的多尺度连续参考站数据质量研究分析

Study on data quality of multi-scale continuous reference station based on TEQC

为清楚了解CORS站点的运行情况以及观测数据质量,结合TEQC软件对香港离岛区五个连续运行参考站观测数据进行质量检核,并结合QCVIEW32对数据质量进行绘图,从多路径误差、观测值周跳比、数据完整性等多方面对数据质量进行分析。通过对五个参考站观测数据在时间上横向和纵向的系统分析,得出如下结论,五个观测站中HKMW站各项数据值比其他站点均要大,CSR值尤为明显,HKMW站多路径误差较大,均不满足中国地壳运动观测技术规程要求。O/slip值低于经验值200,周跳较为严重。

In order to clearly understand the operation of the CORS site and the quality of the observed data,the TEQC software was used to check the quality of the observation data of five consecutive running reference stations in the outlying islands of Hong Kong,and the data quality was plotted in combination with QCVIEW32,and the data quality was analyzed from the multipath error,the observation week and the data quality. Horizontally and vertically in time were analyzed by observing data from five reference stations,the results showed that the data values of HKMW stations was much larger than other stations,and the CSR value was particularly obvious. The multipath error of HKMW station was larger,which did not meet the requirements of the crust motion observation technical regulations in China. The O/slip value was lower than the empirical value. 200,the weekly jump was more serious.
