【摘要】 介绍了基于PANDA软件的高采样率GPS数据非差精密定位方法,为了验证高采样GPS技术与地震仪观测结果的一致性,进行了震动平台模拟数据试验。试验结果表明,高采样GPS和地震仪均能有效地恢复平台震动位移和震动主频率。对2010年Baja地震实际观测的GPS和强震仪进行分析,结果表明,利用高采样GPS技术不仅能成功获取地震波信号;而且能同时获得地表永久形变信息;而地震仪只能获取地震波信息,而不能直接获得地表永久形变信息。更多还原

【Abstract】 In this paper,high-rate GPS data are processed using the non-difference precise positioning technique in PANDA package.It has shown that the high-rate GPS processed results are consistent with seismometer observations.Furthermore,the simulated vibration data and real observing seismic data during the Baja earthquake on 4 April,2010 are employed to test its validation.The high-rate GPS data could successfully capture the consistent seismic wave signal and permanent offset of ground deformation,while seismometer could only obtain the seismic wave.更多还原
