The Study of Electromagnetic Compatibility of Meteorological Radiosondes

Weather radiosondes have been used to study the atmosphere for over 80 years. Data on temperature, humidity, atmospheric pressure, and some other parameters from the corresponding sensors is transmitted by the radiosonde to the ground station via radio channel. Since the advent of the first radiosondes, the situation with electromagnetic compatibility has deteriorated significantly due to the emergence of a large number of electronic equipment, both individual and military-industrial. Cellular communications, broadband access systems operating in close frequency ranges have appeared and are rapidly developing. The number of small spacecraft is constantly growing, some of whose radio channels can affect the signals of meteorological radiosondes. Powerful signals from GSM-1800 base stations can affect the receiving channel of ground-based meteorological systems. The article is devoted to the analysis of the mutual influence of modern sources and receivers of radio signals for various purposes and meteorological radiosondes, as well. In addition, solutions have been proposed and calculated to minimize such influences and improve electromagnetic compatibility for meteorological systems.
