THE ANALYSIS OF GPS-TEC VARIATION RELATED TO LARGE EARTHQUAKES IN SUMATRA

The double-frequency radio signal which is broadcasted by Global Positioning System (GPS) Satellite enables to measure the number of Total Electron Content (TEC). It exists along ionosphere between the signal beam and GPS receiver. The calculation of TEC differential ( dTEC ) and slant TEC use the S...
