INVESTIGATION OF THE INFLUENCE OF METEOROLOGICAL CONDITIONS AND COSMIC WEATHER ON THE INTERFERENCE IMMUNITY OF RADIO NAVIGATIONAL GLONASS/GPS SIGNALS
The estimation methods of the influence of climatic conditions in the surface layer and cosmic weather effects in the Earth's upper atmosphere on signal-to-noise ratio of satellite navigation radio systems are considered. The results of full-scale experiments for winter and autumn periods depending on the air temperature, atmosphere pressure and precipitation, solar and geomagnetic activity are presented.
