The ICT Tracker

The ICT Tracker has been developed in-house and it is a low-cost solution, making it the perfect payload for flights around the world.

  • Fully powered by solar energy
  • Highly sensitive UBlox GPS receiver
  • Solar voltage and temperature monitoring
  • Eletronics weight : ~1 gram
  • Total payload weight : ~4 grams
  • The device beacons within the 14MHz band and it is sending various data using state-of-the-art coding techniques : WSPR and JT9.

    Primary tracking uses WSPR :
  • 6-digit maidenhead locator
  • altitude
  • speed
  • solar voltage
  • temperature
  • health of the on-board GPS reception
  • Secondary tracking uses JT9, encoding the full position (based on 5 decimal plates GPS coordinates) within a single JT9 transmission. This aids recovery if the balloon fails during launch.
