Abstract. The main space-time characteristics of inhomogeneities arising in ionospheric plasma are given. The models of the ionospheric radio channel are shown taking into account the inhomogeneities of large, medium and small scales for navigation satellite systems. The results of measurements and data processing of these systems are presented. It is shown that ionospheric inhomogeneities arising on the propagation path can lead to strong signal fading. According to the depth of fading, scintillation indices are determined, the values of which allow them to be attributed to the class of weak-medium fading. The use of the second derivative phase of navigation signals made it possible to attribute these inhomogeneities to the class of small-scale ones.
Key words: ionosphere, navigation satellites, inhomogeneities, scintillations.
Financing: The work was carried out within the framework of the state task of the Kotelnikov IRE RAS.
