Accelerometer Data

Balloon flight

Data does not necessarily represent the normal downward pull of gravity but rather stresses on the craft as winds pull the craft in various directions.

 

The battery voltage appears to rise as the flight progresses but I think it is the calibration changing due to temperature change on the ‘pic’ microcontroller. (in the range of -50 degrees outside!)
The transmission stopped shortly after Balloon Burst because the antenna was ripped away and lost. During descent, the craft goes through some violent gyrations until it gets into denser air so the parachute can stabilize it.
