High ALtitude Object (HALO)

Based in Kitchener-Waterloo, Ontario, Canada by Alexei Karpenko (natrium42). The launches aim to validate communication and retrieval techniques before more complex missions are attempted.

Launches

  • HALO Flight 1 - 29/09/07 - successful launch and retrieval
    • Down-linked picture thumbnails in-flight using 900MHz XTend radio module
    • Pictures were taken via remote USB feature of Canon camera and scaled down by a Verdex SBC for down-linking
    • Camera failed at about 10km
    • GPS of GM862-GPS module failed at 24km and did not resume when the payload landed, but the module still replied to SMS messages
    • Landing took place onto a minor street in Kitchener and was spotted by a person who called the number on the payload
    • 900MHz XTend radio went out of range (need to use Yagi antenna on the ground instead of high-gain omni-directional)
  • HALO Flight 2 - 08/10/07 - successful launch and retrieval
    • Captured 269 pictures and 58 videos (30 seconds each) with varying camera tilt (up, sideways, down)
    • Reached over 30 km (GPS failed at 24km, altitude estimated based on pressure sensor)
    • Parachute tangled, impact speed was over 60km/h, but everything survived
    • 900MHz XTend radio went out of range (need to use Yagi antenna on the ground instead of high-gain omni-directional)
    • GM862-GPS module failed at 24km, but was automatically restarted successfully and reported landing position via SMS
  • HALO Flight 3 - 21/03/09 - successful launch and retrieval
    • Tested flight computer for Atlantic Halo
    • Tested Venus634LPx GPS chip – fails above 18km
    • Tested SPOT satellite messenger
    • Tested live video and picture broadcasting of the launch preparations
