Outline

画像

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.
The installed PLL oscillator employs narrow FM and conforms to ETSI.

Features

  • Improved temperature and humidity sensor with highest accuracy for the upper-air soundings
  • Two lithium batteries enabling 4 hour sounding and easy operation
  • Proved differential GPS fix based on years of the field experience of the existing model RS-01G
  • Precise time synchronization between temperature / humidity data and GPS data
  • High stability of the ETSI certified transmitter (EN 302 054 V1.1.1)
  • Compact and low-density design, total weight of 150g including batteries, reducing the shocks at the time of falling to the ground
  • An input to a 16bit A/D converter facilitating to connect special sensors; maximum 8 channels for ECC, KC, pressure sensor, etc.
  • Upper compatibility with the existing model RS-01G and capable of using the same receiving unit as RS-01G
