The need to monitor the state of the ionosphere is beyond doubt. Various hardware and software methods are used to study and monitor the ionosphere parameters. Conventionally, they can be divided into ground-based and space-based instrumentation deployment. The result of these methods is various data on the ionosphere. Most studies of this problem verify various models of the ionosphere and/or radio wave propagation using real data.

Investigations of the most common methods of ionosphere research are carried out: vertical, inclined and return-inclined sounding, external sounding of ionosphere from spacecraft, direct and reverse transionospheric sounding, research of ionosphere by GNSS signals (including radio occultation sounding).

The obtained results allow us to conclude that for verification of ionospheric data obtained by different methods, the results of measuring the total electron content and the altitude profile of electron concentration should be used, as well as the need to continue research in this direction.
