The Propagation of Radio Signals Gps at Various Solar Activity

In the present paper the influence of solar activity on navigation system GPS radio signals propagation is considered from the point of view of non-uniform structures occurrence in the ionosphere and their display on registered navigating signals. The analysis was carried out on based of joint application of methods GPS- radio interferometry and specially developed techniques of automatic statistical processing of wavelet-spectra of ionospheric signals registered with the help of global navigating systems GPS/GLONASS. The technique of automatic wavelet-spectra processing is based on the analysis of 2D-sections of wavelet-transformation for the ionospheric signals on the parameter-analogue of frequency. The results of the radio interferometry, wavelet, and spectral estimations for ionospheric inhomogenues structures allocated at stations of a network IGS in various regions - Europe and Northern America - are descussed.
