AGARTALA, March 14 (TIWN): A three member team from South Korea namely Jeong-Won, Jae Won and Dae-Bo had arrived in the state for the test run of GPS Radiosonde by Jinyang, South Korea at Agartala Meteorological Department.

GPS radiosonde is an upper-air sounding instrument for measuring various types of meteorological data; wind speed, wind direction, pressure, temperature and humidity.

Wind speed, wind direction and pressure are calculated from the speed of travel and altitude obtained by GPS positioning techniques; and temperature and humidity data measured from respectively tuned thermistor and electrostatic capacitance humidity sensor.

1 sec sampled GPS data and 1 or 0.5 sampled temperature / humidity data are transmitted over PCM via a TDM network. The transmitted data is automatically processed through a data processor at the surface station.
