In-flight measurement system for radio sounding of atmospher

The high-precision in-flight measurement system is designed to measure the temperature and relative humidity of the surrounding air, determine the coordinates and speed of the radiosonde using the signals from GLONASS and GPS satellite radio navigation system (SRNS), convert the received information into information packages and transmit them via a digital radio channel to the radiosonde signal reception equipment (RSRE). The system provides accurate measurement of meteorological parameters and reliable on-line reception of coordinate and telemetry information to the ground station. The in-flight measurement system consists of a plasticized radiosonde cover envelope, a radiosonde, a holder and a patch cord intended for launching into the high atmospheric layers.
