This method can be applied in regions of the world lacking dense networks of global navigation satellite system receivers and other tools for studying wave processes in the atmosphere and ionosphere. Using this method, variations in the vertical total electron content over Ukraine during the geomagnetic storm of September 23–24, 2020, were analyzed. Large-scale TIDs were observed following the passage of the morning solar terminator and increased auroral activity. A comparison with incoherent scatter data showed good agreement in the periods and time intervals of TID observations detected by both methods. A search was conducted for traveling ionospheric disturbances propagating near key geophysical periods (winter and summer solstices, spring and autumn equinoxes) over Ukraine, along with an assessment of their parameters. The characteristics of TIDs were analyzed depending on the time of day and season. Continuous data collection was carried out using the radiophysical research instruments operating at the Ionosphere Institute observatory. The research results are of interest to space physics researchers, specialists in the rocket and space industry, and experts in satellite communication and global positioning systems.
