Application of High-frequency GPS Data in Seismology by Using Precise Point Positioning Method
Song Guohua · South China Journal of Seismology · 2013
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.
