| 摘 要： | 针对地震、地质构造活动或测站更换接收机或天线等原因导致时间序列中存在粗差的问题,该文通过对站点位置的时间序列的研究分析,可以获取板块运动规律、地球震荡周期变化等信息,这对维护和更新地球参考框架,探究和揭示大地构造变形运动过程、动力学机制及地震活动等相关科学问题具有十分重要的意义。对全球分布的34个IGS站周解坐标时间序列,分别采用3RMS准则和IQR准则进行粗差的剔除,得出低高纬度更适合3RMS准则,中纬度比较适合同时应用两准则结论,为后续研究提供了良好的数据基础。

| Abstract: | The position time series about high precision GPS site,which is high-precision location information sequence after calculating the observation data.Owing to earthquake,tectonic activities,or replace receiver antenna,it is inevitable existence of gross error in time sequence.Therefore,accurate positioning and eliminate the gross error in time sequence is the basis of sequence analysis.Based on the research of the site location of the time series analysis,there can obtain the information such as plate motion,earth shock cycles.It has vital significance to maintain and update the earth frame of reference,to explore and reveal the tectonic deformation motion process,dynamic mechanism and relevant scientific problems.Based on the weekly coordinate time series of 34 IGS stations,using 3RMS and IQR to eliminate gross error,there reach the conclusion that low and high latitudes is more suitable for 3RMS standards,mid-latitude suits both standards,which provides a good data foundation for follow-up study. |
