Summary: | Abstract — The dual frequency Global Positioning System (GPS) receiver provides an opportunity to determine Total electron content widely used to study the dynamics of the ionosphere. For this purpose a dual frequency GSV 4004A GPS receiver is installed at sub auroral region over Indian base polar station Maitri (71.45 S Lat,11.45 E Long), Antarctica. In this paper to discuss the behavior of TEC has been studied using GPS data. The diurnal and seasonal variation of VTEC is studied for different seasons. GPS derived TEC is than compared with International Reference Ionosphere (IRI) 2007 model. From the analysis we observed that TEC achieves its highest value during the summer as minimum in winter. Also observed maximum TEC value of Polar Day month (December) because during these months the polar cap receives the solar radiation round the clock as compared to Polar Night month (June). We use only those GPS satellite data whose elevation angle is greater than 300 for TEC during at low solar activity period December 2009 to December 2010. |
