During the first stage of work, an algorithm for calculating the vertical ionograms for the central point of the radio path using data of oblique ionospheric sounding with an active ionosonde at the Ukrainian Antarctic Station “Akademik Vernadsky” and a passive one on board the research vessel “Noosphere” was implemented and tested. Synchronous measurements of high-frequency (HF) signals on long distance radio paths were processed and analyzed to monitor and identify the ionospheric disturbances of a global scale. An approach to calculating median spectrograms for specified time intervals was tested to more correctly assess the average conditions for ionospheric propagation of HF radio signals on long distance radio paths. An analysis of the propagation channels of radiation from power supply networks in North America at a frequency of 60 Hz recorded at the UAS was carried out in order to study the anthropogenic impact on the electromagnetic environment and climate of Antarctica. The variations of the time derivative of the integrated illumination of the RWM-UAS radio path were calculated. The same approach was applied to the simulation of the variations of the Doppler frequency shift (DFS) of ionospheric signals propagating through the solar eclipse area on April 8, 2024.
