Company Profile
GRAW is a well-established German company developing and manufacturing Upper Air Sounding Systems since 1938.
GRAW's digital GPS Upper Air Sounding system meets all requirements of aerological measuring technology, be it as a routine Radiosonde for use by meteorological services, for military applications or as a research Radiosonde for scientific purposes.

Some "highlights" of the GRAW digital GPS Radiosonde are:
  • "Online"-ground check, no separate unit necessary
  • Very compact (8.5 cm x 8.5 cm x 4.5 cm, ready for start)
  • Very light weight (< 90 grams, ready for start!)
  • Very simple handling (e.g. power activation by ON/OFF switch)
  • Highly sophisticated transmitter (deviation < 4 KHz, bandwidth < 10 KHz)
  • Code correlated differential GPS with protected antenna for wind finding
  • High-power environmental friendly lithium battery
Different versions of ground stations are available, starting from extremely mobile and low-cost solutions in the size of a mobile phone and ending at a highly robust field PC for mobile military applications.

Special EMI-filters protect the system against high-power radar signals, lightning or other external influences. The product-range of GRAW is completed by Radiosonde dereelers and automatic balloon filling units.
