Zusammenfassung:FIELD: radio engineering.SUBSTANCE: invention relates to radio engineering and can be used in atmosphere radio sounding systems based on use of signals of global navigation satellite systems (GNSS). Atmospheric sounding navigation system comprises N transmitters of GNSS signals, ARS, GNSS signal receiving antenna system, antenna system for receiving an ARS signal with a circular beam pattern, antenna system for receiving an ARS signal with a narrow beam pattern, provided with an elevation-azimuthal drive, antenna switch, base station with an information display and input/output unit, microwave switch, wherein GNSS signal receiving antenna system is connected to base station, antenna system for receiving ARS signals with a circular beam has a near-channel antenna and a far-channel antenna, outputs of which through switch and microwave switch are connected to base station, respectively output of base station is connected to elevation-azimuthal drive of antenna system with narrow beam pattern, output of which is connected through microwave switch to base station. Antenna system for receiving GNSS signals provides accurate determination of coordinates of base station, antenna system for receiving ARS signals with circular beam pattern provides reception of ARS signals at its vertical lifting and distances of up to 250 km, antenna system with narrow beam pattern provides reception of ARS signal at distances over 250 km and high-interference environment.EFFECT: high accuracy and reliability of determining spatial coordinates of an aerological radiosonde (ARS), wind direction and speed, high noise-immunity and electromagnetic compatibility.1 cl, 1 dwg Изобретение относится к радиотехнике и может быть использовано в системах радиозондирования атмосферы на основе использования сигналов глобальных навигационных спутниковых систем (ГНСС). Достигаемый технический результат - повышение точности и надежности определения пространственных координат аэрологического радиозонда (АРЗ), направления и скорости ветра, повышении помехоустойчивости и электромагнитной совместимости. Указанный результат достигается за счет того, что навигационная система зондирования атмосферы содержит N передатчиков сигналов ГНСС, АРЗ, антенную систему приема сигналов ГНСС, антенную систему приема сигнала АРЗ с круговой диаграммой направленности, антенную систему приема сигнала АРЗ с узкой диаграммой направленности, снабженную угломестно-азимутальным приводом, антенный переключатель, базовую станци
