Well, I am actually at the moment in the process of prototyping bits for
a star tracker that will work under relatively heavy vibration, accelleration,
and rotation, with an all-up weight of ~100g or so, maybe. (with great
difficulty and many hundreds of tests.)
Admittedly, things get a little more expensive if you can't use a standard
motherboard, but there are lots of fast single-board-computers out there,
and a custom design is not impossible.
Then again, there is fast, and there is fast.
I suspect a 1300Mhz or so PC type processor is dramatic overkill for what
