High Altitude Ballooning
Calgary and Area
"Poor Mans Space program"
This flight was a test with a transmitter running around 10 mW. The balloon was launched from inside Calgary. The balloon was predicted to fly to around vulcan. Average speed was estimated around 70 KM/h. This was a test of using cheap (foil 3 foot) party balloons inflated with H2 gas. Rate of ascent around 300 feet/min. Payload mass is 15 grams with a 6Volt battery pack.
The transmitter was on 433.945mhz and we tracked it from inside my house. We could pick up clearly upto 20 minutes, after that the signal was very week, it was probably decending. possible 30km range of the balloon.
This launch used around 3.5cubic feet of H2 (total) and the payload total weight was 15 grams. We used field-hell, rtty for this flight. field-hell as always was very easy to decode, rtty dropped accuracy quickly.
