Currently, the developers of global navigation satellite systems (GNSS) are making significant efforts to solve a number of fundamental problems. However, ignorimg by researchers the entire set of nonequilibrium physical and chemical processes occurring in the ionosphere, which affect the propagation of satellite signals, often does not allow to have a progress in their solution. In this paper, we discuss the main chemical reactions that occur in the lower ionosphere of the Earth with the participation of the Rydberg states of O2, N2, and NO molecules. An explanation of the physical reason for the time delay of the satellite signal, leading to errors in GNSS positioning, is given. A quantum approach is proposed, through which the transition from the traditional idea of the propagation of radio waves to the movement of the corresponding photons is carried out. In this case, the effective delay time in resonant photon scattering is determined by the characteristic lifetime of the intermediate autoionization states of vibrationally excited Rydberg complexes. The value of the lifetime is defined by the presence of a strong nonadiabatic coupling of the electronic and nuclear motions in the intermediate states of the complex, which does not depend on the strength of the external field created by the GNSS transmitter.
