| 摘 要： | 在介绍利用Track处理长距离动态GPS数据的原理与方法基础之上,本文针对地震监测GPS数据处理,提出了一种新的探测地震主震和余震的历元间求差法.新方法先通过Track解算出较精确的坐标,在相邻历元问求坐标差与计算出的限差进行比较来判断是否发生地震.利用美国圣西蒙GPS地震数据,分析了长距离动态GPS数据处理精度,对历...

| Abstract: | Based on the introduction about the principles and methods of processing long range kinematic GPS data using Track,aiming at Seism Monitoring data processing,a new method was proposed called adjacent epoch difference method to detect the earthquake and aftershock in the paper.The method suggested after getting the precise coordinates using Track,by comparing the value of adjacent epoch difference and the tolerance computed to determine whether the earthquake occurred.The American San Simeon earthquake GPS d... |
