“…We note that the general scheme of resonance scattering of photons on highly excited Rydberg molecules significantly differs from the traditional scheme of the processes described in [12], which in principle cannot lead to a time delay. We also note that in the problem of resonance scattering of a Rydberg electron, the presence of predissociation channels should be taken into account when considering the dissociation of complexes for various fragments of a neutral medium independently [24]. Thus, the theory of propagation and distortion of satellite signals should include simultaneously the contributions of all three mentioned types of the radiation processes.…”

GPS signals play a very important role in the modern industry, science, tourism, military and domestic operations. However, GPS signals are not free from some mistakes caused by disturbances appearing in D and E layers of the atmosphere. A quantum approach is proposed to the theory of propagation of a satellite GPS signal through the D and E layers of the atmosphere, which reduces to the problem of scattering of photons moving in the electromagnetic field of a signal in Rydberg complexes formed in a two-temperature non-equilibrium plasma. The processes of creation of additional photons as a result of stimulated emission and resonance scattering of photons are considered. It is shown that the first process leads to a direct increase in the power of the received signal, and the second to a shift in the signal carrier frequency and the time delay of its propagation. This occurs because of the scattering of the Rydberg electron by the ion core and the neutral medium molecule in the intermediate autoionization states of the composite system populated by the strong non-adiabatic coupling of electron and nuclear motions.

“…However, analysis of literature indicates that the main efforts of engineers and researchers are concentrated only for the improvement of the transmitting and receiving equipment of navigation systems without attempts to study the natural phenomena occurring in the Earth's atmosphere. We believe that the most problem is to find out which physical and chemical processes affect the propagation of radio waves in atmosphere at this frequency range [26]. Rydberg complexes A**M whose states are split due to the interaction with a neutral medium and between which the radiative transitions occur [19].…”

“…The selectivity of the effect at the frequencies L 1 and L 2 is due to the nonmonotonic character of the UHF spectrum which depends on the level of solar activity [24] [25] [26]. In the mentioned publications, the basement of the theory was developed and the "Rydberg" program was created.…”

“…the received signal differs from the original one that cannot occur from the incoherent radiation of the Sun. Such a behavior of the signal can be explained by the fact that it is a subject of the resonance effects of the propagation medium, the nature of which is currently under intensive study [21]- [26].…”

When the satellite signal passes through these layers, multiple resonance scattering of photons occurs on the orbitally degenerate Rydberg complexes A**M, whose states are split by interaction with the neutral medium; between two last subjects occur the radiation transitions [26]. …”

A detailed analysis of the influence of Rydberg states to the behavior of GPS satellite signals in the D and E atmospheric layers has been carried out. It is demonstrated that these states are the main reason for the GPS signal distortion. It is shown that the behavior of satellite signals is associated with the spectral characteristics of the UHF radiation of the Rydberg states depending on the geomagnetic conditions of ionosphere. The foundations of the quantum theory of distortion and delay of GPS satellite signal propagation through D and E atmospheric layers are analyzed and expounded. The problem reduces to the resonant scattering of photons, moving in the electromagnetic field of the signal, to the Rydberg complexes populated in a two-temperature non-equilibrium plasma. The processes of creation of additional photons because of stimulated emission and resonance scattering of photons are considered. In the present work, the quantum theory of the propagation of a satellite signal in the Earth's upper atmosphere, firstly earlier proposed by the same authors, is described in detail. The general problems of the theory and possible theoretical and applied consequences are discussed. It is explained that two main processes occurring here, are directly related to the resonant quantum properties of the propagation medium. The first process leads to a direct increase in the power of the received signal, and second-to a shift in the signal carrier frequency ν ∆ and the time delay τ ∆ of its propagation. The main reasons of the processes are scattering of the Rydberg electron by the ion core and presence of the neutral medium molecule in the intermediate autoionization states of the composite system populated by the strong non-adiabatic coupling of electron and nuclear motions. The main purposes of our investigation are the physical justification of the formation of parameters ν ∆ and τ ∆ using the quantum dynamics of the electron behavior in the intermediate state of the Rydberg complex A**M and the esti-
