The UBSEDS16 balloon was built from 50 micron thick PA-EVOH-PE multilayer film and was 1.5 meters in diameter. The payload weight, including insulation, was 58 grams. We aimed for 25 grams of free lift to give a slightly higher ascent rate than usual, and the helium fill resulted in 26.5 grams of free lift. This initial float altitude was 10.6km (35,000 ft).
The flight was intended to test the superpressure balloon with a heavier payload. After floating for nearly 4 hours the balloon failed, and it landed in France.
The tracker was built mostly from spares, and used a leftover PCB from UBSEDS10 and 11.
The balloon transmits approximately once every 30 seconds.
It uses the error-correcting Contestia 16/1000 mode on 434.612.5MHz USB.
