Abstract:  Forty years of progress of the radio beacon research of the ionosphere carried out in India using the signals from both orbiting as well as geostationary satellites by various researchers has been briefly reviewed. Several features in the typical equatorial and low latitude characteristics on the occurrence and morphological behaviour of the total electron content (TEC) and the ionospheric scintillations are presented. The need for the measurement of absolute TEC, its real time prediction as well as the prediction in the onset of scintillations, their amplitudes and durations, in the context of the possible application of these space weather phenomena in the satellite based communication and navigation systems, with particular reference to the effective implementation of the programmes such as GPS Aided Geo Augmented Navigation (GAGAN) are discussed.
