Launch Parameters

Balloon and Payload

  • 36" Qualatex, unstretched
  • 36.7 gram payload
  • 3.3 grams free lift
  • Half-wave antenna.

Heat sealed neck.


Experiments

  • Not using TCXO for AVR. Uses power and I want to see if I actually observe an issue.
  • ATGM332D GPS.

Predictions

Actuals

Actually a pretty reasonable flight.

Flight software worked great. No need for TCXO for AVR seemingly, as signals were plentiful.

Lots of long-distance signals.

Cause of death uncertain.
