A radial basis function (RBF) neural network is developed to be used for short term prediction of the ionospheric total electron content (RBFNNTEC). The RBFNNTEC has been developed from single station of IGS data at low latitude region in Indonesia to predict 24 hour ahead of TEC and ionospheric disturbance index for GNSS user. The estimated TEC overhead of GPS station at BAKO (6.68°S, 106.85E) and Dst index for 12 months in 2016 are used for training data set, validating data and test data set of RBF network model. The performance of the trained model is evaluated at a set of criteria. Our results show that the predicted TEC is in good agreement with observations with mean relative error of about 11

% and root-mean-square error of less than 7 total electron content unit. Our comparison

further with global ionospheric maps (GIM) prediction indicates that RBF network offers a

powerful and reliable tool for the design of ionospheric TEC prediction.
