Investigation of Methods for Ensuring Electromagnetic Compatibility of Atmospheric Radiosonde Systems

Upper-air radiosondes, which transmit coordinate-telemetric information on the main meteorological parameters to the ground station, contain a transmitter and, in some cases, a receiver of GLONASS / GPS satellite navigation systems. The known methods providing electromagnetic compatibility of transmitting and receiving systems cannot be fully applied in this case, taking into account the specifics of the radio sounding system. This paper is devoted to the development and study of methods for reducing the influence of out-of-band emissions from a radiosonde transmitter on navigation signal receivers and other communication systems operating in close frequency bands.
