A change in the phase of the depileve easy clean received signal during a total solar eclipse on 31 July 1981 is considered.Theexperimental data were obtained from the phase of the signals received by the Omega radio navigation system.The distribution path captures both the auroral oval and the mid-latitude zone.It is shown that it is very difficult to distinguish 5326058hx the phase deviation of thereceived signal during a solar eclipse.Other parameters that affect the propagation of signals in the auroral zone must be taken into account.
