Title:GPS-TEC measurements at low latitude using UNB Ionospheric Modeling Techniques

Abstract:UNB Ionospheric Modeling Techniques computes TEC from GPS observables at both L1 and L2 frequencies in order to provide ionospheric corrections to communication, surveillance and navigation systems operating at one frequency. The software estimates the coefficients of a linear spatial approximation of TEC over each station in addition to the satellite and receiver differential biases, modeling the ionospheric measurements from a dual frequency GPS receiver with the single-layer ionospheric model. The GPS data of IGS Hyderabad station (17.410N, 78.550E), Bangalore (13.020N, 77.570E) and Kolhapur station (16.8˚N, 74.2˚E) have been used to measure Total Electron Content (TEC) of the ionosphere during the period of different geomagnetic storm events. The effect of the geomagnetic storm on ionosphere shows an increase in the VTEC values, followed by sudden decrease in Dst values in some storm cases. In the next few years there will be ample opportunities to study in detail solar- terrestrial events using UNB Ionospheric Modeling Techniques for better understanding of the effect of solar activity on Total Electron Content (TEC) at low latitudes.
