高频GPS数据地震应急处理方法研究

Abstract

Abstract: In GPS Kinematic Positioning mode, High frequency (≥1 Hz) GPS data processing needs satellite clock error of sampling intervals of 30 s or higher rate. However, IGS ephemeris products that meet the needs will delay 12~18 d. Obviously, conventional GPS data processing can not meet earthquake emergency needs. A new processing method of high-frequency GPS data for earthquake emergency is put forward in this paper. The displacements of surface deformation can be obtained within several hours after earthquake occurrence. And this method was demonstrated in GPS data processing following the 2013 M_S7.0 Lushan Earthquake.

Key words: GPS data processing, Kinematic Positioning, Earthquake Emergency, The 2013 M_S7.0 Lushan Earthquake
