| Popis: | The influence of the ionosphere on propagation of short radio waves is considered. Data on the monthly average diurnal values of critical frequencies at midlatitudes are presented. The applicability of the radio-sounding method to investigation of the state of the Earth’s ionosphere is demonstrated. Comparison of the data obtained from the path sounding of the ionosphere and from the radio-sounding method is performed. It is shown that satellite navigation systems can be used for prediction of the propagation conditions of short radio waves. |
