【摘要】 在研究GPS单历元定位方法基础上,利用GAMIT GPS数据处理软件中的动态定位模块Track,分别得到了动船的运动轨迹和2011年3月日本地震发生后4个IGS站的位移量。实验结果表明:Track模块解算动态GPS数据能得到清晰的动船运动轨迹;采用TRACK模块解算地震发生时的GPS观测数据能够得到地震后的位移特征,且能有效探测主震发生时间。更多还原

【Abstract】 Based on the study of single epoch GPS positioning method,the true trajectory of a moving boat and the post-earthquake displacement of four IGS stations in Japan were respectively obtained with the kinematic positioning module of GAMIT software Track.The results showed that using Track module to process kinematic GPS data could get clear trajectories,and using it to process seismic GPS data could get the post-earthquake displacement characteristics,the time when earthquake happen could be efficiently detected also.更多还原
