Comparative analysis on sudden ionospheric disturbance

Abstract

The effect of sudden ionospheric disturbances on the phase of the received signal on four paths is considered. The experimental data were obtained from the phase of the signals by the radio navigation system Omega. Paths are almost the same length. The transmitters are located at two points. It is shown that the phase deviation of the received signal obeys the Poisson distribution. It is necessary to take into account the seasonal variations of the electron density.
