GPS Radiosonde
RS-11G● Improved temperature and humidity sensor withhighest accuracy for the upper-air soundings
GPS Radiosonde Sounding System RD-08, Fullcode correlating GPS radiosonde ground station
ensures capturing reliable and accurate upper-airweather.
This lightweight and compact sounding system isintended for increased portability andconveniences in sounding. Your sounding
experiences will be extended more than ever.
The corresponding GPS radiosonde, RS-11G
carries a temperature sensor and humidity sensor.
Pressure is calculated from the GPS altitude
measured by single point positioning. Sounding
duration lasts 180 minutes, allowing vast stretchesof sounding possibilities. Abundant choices ofinterfaces expand the use of supplementalsensors.

● One lithium battery enabling 3 hour sounding

approximately and easy operation● GPM by SBAS method GPS positioning● Precise time synchronization between tempera-ture/ humidity data and GPS data
● High stability of the ETSI certified transmitter (EN302 054 V1.1.1)● Compact and low-density design, total weight of 85g

including batteries, reducing the shocks at the time offalling to the ground● An input to a 16bit A/D 6ch and Serial input

con-verter facilitating to connect special sensors; for
ECC, CO2, OPC, FLASH, Cloud particle, etc.
