GPS radiosonde is an Upper-air sounding instrument flying with weather balloon. As the balloon ascends, radiosonde measures variety of meteorological data; wind speed, wind direction, pressure, height, temperature and humidity. Wind speed, wind direction and pressure are calculated from the travel speed and altitude obtained by GPS information. Temperature and humidity data are obtained from dedicated thermistor and electrostatic capacitance humidity sensor, respectively. Measured data are transmitted to ground receiving system every second using 400-406 MHz band.
Redesigned sensor boom achieves higher accuracy in temperature measurement. Also, newly developed high response humidity sensor enables more accurate humidity measurement even in low temperature environment. RS-11G enables various kinds of soundings through expansive interfaces, such as MTR (16 Hz temperature sampling), CFH (Cryogenic Frostpoint Hygrometer), Radioactivity sonde, ECC Ozone sonde, Cloud Particles Sensor (CPS), etc.
