More accurate definition of the characteristics of the ionospheric radio wave propagation according to the OS “Mir” data

One of the best ways to determine the parameters of the ionosphere and use them to refine the model is to measure them with the orbit station. Results from one of these experiments were obtained in 1999 on the OS “Mir”. This allowed to refine characteristics of the ionospheric radio wave propagation such as foF2, M3000F2, MUF3000F2 and others in areas inaccessible to ground-based sounding, in particular, in the equatorial regions, and estimate the deviation of the model from the experimental values.
