【摘要】 使用武汉大学提供的PANDA软件,对高频GPS数据利用非差精密定位方法进行处理。对观测点记录到的代表不同震级及震中距的几个地震的高频GPS数据分析结果和地震仪进行同震效应的对比分析。结果表明:GPS可以很好的测量地震时期的地震波信号,同时对地表的永久性位移也有一定的反映,可以发展成为新型的GPS地震仪。GPS高频数据对于震级大、震源深的地震其捕获能力更强。GPS高频数据可以对测点强震仪起到很好的补充作用,但其处理软件的精度和模型还有待于进一步的提高。更多还原

【Abstract】 Using the PANDA software provided by Wuhan University and non-difference precision positioning method,this article processed high frequency GPS data,and done a comparative analysis of the coseismic effects of several earthquakes with different magnitude and epicentral distance,which recorded by high-frequency GPS data and seismograph data.The results show that GPS can be good for measuring seismic signals,have a certain reflection on permanent displacement of the surface.So it can be developed to become a new GPS seismometer.High-frequency GPS data have stronger ability in capturing earthquakes with large magnitude and focal depth,and it can play a complementary role for strong motion seismograph.But its accuracy and precessing model of software should be further improved.更多还原
