Abstract

The problem of studying ionospheric disturbances is not only of scientific interest, but also has many important applied aspects. It is known that during solar flares there is a powerful burst of radiation intensity in different wavelength ranges, which has a significant impact on the Earth’s ionosphere. That is why during periods of high solar activity there are significant quantitative changes in the structure of the ionosphere.1 The development of GNSS systems has made it possible to obtain new data both on the state and dynamics of the ionosphere with respect to heights, and on the integral characteristics of the medium (total electron content - TEC) under various heliogeophysical disturbances. The technique presented in this paper made it possible to automatically evaluate the change in TEC caused by solar flares of various classes according to the data of a spatially distributed network of GNSS receivers.
