摘要：Ionospheric nowcasting and forecasting tools are necessary for high precision applications in equatorial regions such as India and Brazil, etc. An algorithm capable of predicting the ionospheric behavior in advance can be used to setup early warnings for GPS applications. In this paper, Neural Network (NN) model using back propagation algorithm is implemented over a low latitude GPS station (Hyderabad). The preliminary results indicate that, NN model values are closely following with actual data. It is found that, the prediction error is varied maximum up to 1TECU. Advanced NN models would be useful for forecasting ionospheric characteristics in a robust manner.
