实时高频GPS在地震学中的应用研究
|
摘要
以TrackRT软件为例介绍了实时高频GPS技术的数据处理方法,通过与测震(强震)的比较,认为该技术可获取可靠的长周期位移,对测震(强震)资料进行有效弥补。并系统地阐述实时高频GPS技术在地震学中的应用方法,表明在我国开展实时高频GPS方面的研究具有十分重要的实际意义。
Taking the TrackRT software as an example,we introduced the data processing method of the real-time high-rate GPS technology.Comparing with seismometry(strong motion),this technology could obtain the reliable displacement in long period,effectively remedy the data of seismometry(strong motion).Then we systematically describe the application methods of real-time high-rate GPS in seismology.It has very important practical meaning for developing real-time high-rate GPS technology in China.
