N, Longitude 11.45?E) Antarctica, during the low solar activity period (Jan.-Dec. 2008). Monthwise TEC values are highest during the months of January and December, as compared to June month. As regarding seasonal variations, in winter months i.e. June, July and August 2008, TEC values were lowest because ionization process are very low, due to the absence of sunlight; whereas during southern summer season TEC values reaches its maximum, due to the presence of 24-hour sunlight and hence the ionization radiation from the sun. We have processed and analyzed GPS data of the year 2008 from Indian base station Maitri, Antarctica. This shows the presence of strong relationship between GPS -TEC and its dependence on solar activities. In the first month of January, TEC value goes to a high as compared to June month. TEC value again goes to a high in December month. It is because in January and December months, solar activity is high as compared to June month. The seasonal study of TEC shows that total solar activity is absent in winter season and due to no ionization processes, TEC value goes to the minimum.
