深圳市连续运行参考站稳定性分析
|
摘要
针对深圳市连续运行参考站的稳定性分析相对较少的现状,基于深圳市2015年CORS数据,该文利用GAMIT软件计算并分析了参考站间基线以及与IGS站间基线的稳定性。结果表明,除因南山站点位异常引起了部分基线出现偏差外,大部分基线表现稳定且水平方向稳定性高于垂直方向。该文通过基线的稳定性分析方法,能够较为直观地检查出点位出现异常的参考站,这对于CORS站服务性能评估具有一定的参考意义。利用GLOBK软件平差得出了参考站坐标时间序列,并与PANDA的精密单点定位结果进行了对比分析;使用了SPSS软件的相关性分析法计算IGS站与参考站坐标变化的相关系数,得出SZCORS各参考站向东南方向偏移的趋势与板块漂移具有明显的相关关系这一结论。
Aiming at the current situation that there is few stability analysis of Shenzhen CORS,the software GAMIT was employed based on Shenzhen CORS data in 2015 to compute and analyze the inner baselines among these reference stations and outer baselines between an IGS station and reference station.The result showed that most baselines behave stable and horizontal components were more stable than the vertical,in spite of some baselines' deviations caused by positional abnormity of Nanshan station.By means of stability analysis method in this paper,the abnormal stations could be inspected intuitively,which would be meaningful to the performance valuation of CORS station to some degree.Then the time series plots of daily position were drawn,which made a compare and analysis with the baseline and coordinate results computed by PANDA software.Finally,the method of correlation analysis was employed to work out the correlation index between the IGS station and reference stations,which drew a conclusion that the motion trend to south and east of the SZCORS stations had an apparent positive relationship with continental draft.
