Method Monitoring and Predicting to Solar Flare Using GPS

In order to studying the means of monitoring and predicting to solar flare,the observation data of more than 60 global GPS trackingstation from IGS is downloaded,TEC that coming from two solar flare of X level is calculated and analyzed.The results show that the sudden increasing phenomenon of TEC is monitored in solar flare,which all GPS tracking-stations locate the high latitude area and the low latitude area,and it is consistent with the figure of X ray flux;difference TEC can gain more exact change of total electron content,so it adapts to the detailed study of solar flare;the phenomenon of TEC great range jumping is discovered in studying absolute TEC range between closer-day,so the experimental viewpoint and conclusion are obtained.
