基于PPP技术的GPS浮标海啸预警模拟研究

Simulation of Tsunami Forecasting with GPS Buoy Using PPP Technology

    摘要
  • 摘要: 提出了利用精密单点定位(precise point positioning,PPP)技术进行海啸预警的方法,并利用TriP软件对实测浮标数据进行了处理,将得出的海面高数据和海啸波模型叠加进行了模拟分析。仿真结果表明,利用精密单点定位技术进行海啸预警,能够监测判断海啸的发生,并获得海啸波到达海岸的波高和时间,提供一定的预警信息。

     

    Abstract: A new tsunami forecasting method employing PPP(precise point positioning) technology is proposed.With the field data of GPS buoy being processed using self-developed software Trip,the simulation results which combine the height datum of sea level and the simulated tsunami model are analyzed.Ultimately the simulation results show that PPP technology can determine tsunami,and forecast the message on the amplitude and arrival time of probabilistic tsunami to a certain extent.
