Investigation of the Influence of the Radiosonde Transmitter of the 1680 MHz Range on the Reception of GLONASS Signals by a Navigation Receiver

A systematic study of meteorological parameters of the atmosphere using radio sounding systems is important for various branches of human activity, since weather and climate forecasts are formed on their basis. Various methods of such studies are known, among which the most effective is radio sounding with the help of aerological radiosondes launched into the free atmosphere. Radar, radio direction-finding and radio navigation methods of sounding have received practical application. Improving the operational characteristics of the SR is possible by combining the capabilities of radar and radar navigation methods. However, due to the close relative position of the operating frequency ranges, the ARZ transmitter may affect the navigation signal receiver of the GLONASS GNSS radiosonde. The present work is devoted to the study of the issues of electromagnetic compatibility of these devices.
