The paper aims at providing the technical information about Doppler vertical sounding of the ionosphere that started at the Ukrainian Antarctic Akademik Vernadsky station since 2017; developing the technique for processing and visualization of data of vertical sounding of the ionosphere in the form of height-time diagrams of median values of ionospheric parameters; demonstrating the capabilities of this technique using the results obtained during the first year of observations, namely the background variations of ionospheric parameters as well as examples of observations of travelling ionospheric disturbances (TID). The methods used in the paper are the following: the vertical sounding of the ionosphere using the IPS-42 ionosonde operating at Akademik Vernadsky station since 1982; Doppler vertical sounding of the ionosphere by the portable ionosonde developed and manufactured in collaboration between the Abdus Salam International Centre for Theoretical Physics (ICTP) and Institute of Radio Astronomy of the National Academy of Sciences of Ukraine (IRA NASU); calculating the height-time diagrams of ionospheric parameters obtained using the data of both ionosondes; and original technique for estimating the median height-time diagrams as background monthly averaged characteristics of the ionosphere.
