Sažetak
The proposed study represents a continuation of the research regarding standard GPS ionospheric delay mitigation. Globally distributed locations were elaborated in terms of positioning solutions, with analyses of the horizontal component of positioning error. The ionospheric delay was calculated on the basis of raw pseudoranges and compared with modelled values. The horizontal GPS positioning error was observed in three main ionospheric regions during the geomagnetic storm which took place in March 2015. Residuals between real and modelled values suggest different behaviour of positioning patterns depending on location. Increase in residual values appears notably after the commencement of the disturbance. The conducted study and noted observations open further possibilities for research in this domain of satellite positioning error mitigation.
