I'll have a look into it. For a start, it will possibly be sufficient to
use the position data from the IMU as GPS replacement and query
accelerations and angular rates seperately for PID only.

So UART is the only way to connect, no chance for the Tiny?

It helps me in selecting the hardware to buy :-). I'll let you know, but
most probably not before next year.

The probe itself must have been built at the institute here, but no
documentation is left, so nobody knows for sure. The attached sensors
are standard SMD pressure sensors.
