Equatorial region is an area of particular interest not only for space scientist but also for the Earth space radio communication engineers. The upper atmospheric behavior of equatorial region is quite different from the rest of the Earth because of the presence of densely charged particles. There are still many things which need to be discovered in the upper atmosphere and there is still lack of research in this specific area. Statistical study of seasonal and geomagnetic effects on Equatorial Ionospheric Anomaly (EIA) during solar cycle is done for solar cycle 23. TEC mapping using GPS data is relatively a new technique for space weather observations.
