Our cost-effective pilotsonde


Pilotsonde PS-15

  • Very small and lightweight
  • Wind-detection by 48 channel GPS
  • Data transmission in 400 MHz band
  • Optional XDATA interface for external sensor


Our latest innovation – the pilotsonde PS-15

The pilotsonde PS-15 is based on the well-established high quality GRAW radiosonde system DFM. In fact, it is a GPS radiosonde without sensors for humidity and temperature. It can replace conventional Pilot soundings with optical radiotheodolites by a fully automatic sounding system at very low costs. The PS-15 is fully compatible with all GRAW Upper Air Sounding Systems and can be used in combination with normal PTU radiosondes. The optional XDATA interface allows using the telemetry of the PS-15 for transmitting any external sensor data down to the receiving system.
