Change of the VLF-range signal phase on the transparency track during a total solar eclipse

A change in the phase of the received signal during a total solar eclipse on 31 July 1981 is considered. The experimental 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 the phase deviation of the received signal during a solar eclipse. Other parameters that affect the propagation of signals in the auroral zone must be taken into account.
