Descriptions of statistical models of narrow-band transionospheric radio lines with amplitude fading of signals due to the influence of the earth’s ionosphere are given. The models are based on the analytical description of signal propagation in randomly inhomogeneous media that generate temporal variations in signal amplitudes due to their reflection and scattering on ionospheric inhomogeneities. These analytical descriptions represent Rytov’s approximate solutions for the wave equation without taking into account the anisotropy due to the influence of the Earth’s magnetic field. The stationarity of the radio line associated with the temporal and spatial statistical characteristics of random temporal and spatial fluctuations of the electron density of ionospheric irregularities is considered as a parameter of the models that is important for applications. By calculating the considered models of radio lines with the parameters of the standard mid-latitude ionosphere, estimates of the temporal stationarity of radio lines for a number of velocities of movement of ionospheric irregularities are obtained. The calculated estimated values of the temporal stationarity of the considered radio lines due to the influence of the ionosphere are useful in the development of satellite information systems, in the selection of optimal signal structures and in the development of procedures for their processing during reception and synchronization.
