We'll be launching as part of a collaboration with the University of Sydney Rocketry Team today, under the moniker Horus 5/SARP.
Weather predictions are not favourable, but time constraints are forcing launch. Expected landing site is approx 180km from launch:
Adrian VK5ZSN will head off to the predicted landing site ahead of time with half the team, as it's unlikely we'll be able to match the balloon's speed - once the balloon is launched we'll try to keep pace as best as possible in the second chase car.
Telemetry will be 100b RTTY with 500hz shift on 434.650 MHz sideband. The flight can be tracked online here.
