It's ... complicated.

MAX GPS RF front end -> STM32 running ChibiOS, to ethernet -> custom
8-port ethernet switch & power management board -> Intel Atom primary
flight computer running a pretty vanilla linux kernel -> CF card on
the motherboard.


I'm sure we'll figure it out eventually. We've been working on a
overview paper of the flight and it's data, I'll probably post it here
when we're done tying up loose ends.

Nathan,
Can you charactorize the data loss in your GPS data?


On average we have runs of about 20 seconds of good data with ~1 to 50
millisecond gaps. No regular pattern is obvious.


Can you describe the storage process?
What OS do you use?
