Sažetak
The paper analyses variability of the ionospheric Total Electron Content (TEC) over European middle latitudes, obtained from Global Navigation Satellite Systems (GNSS) observations. Although characteristics of the ionospheric activity at middle latitudes are usually well modelled compared to low and high latitudes, models usually do not take into account the local irregularities and response very slowly to fast developing ionospheric disturbances. To detect ionospheric irregularities and obtain information of ionospheric gradients, we used the TEC rate of change (ROT) and calibrated vertical TEC (VTEC) data. For observation of spatial behaviour of ionospheric fluctuations we used TEC data from several GNSS stations situated in the same geographical area. A tool for geographical representation of VTEC values and the TEC rate of change (ROT) was developed. Produced graphical and numerical representation was used for preliminary analyses of ionospheric fluctuations over middle latitudes during the periods of low and high geomagnetic activity.
