I assume then that you are abt. 2 or 3 hours by car from me in the
south/western direction.

Yes, if the FPGA gets warm from the radiation, that won't work. :-)
But good enough for space probes or devices on the ISS. After all,
there live some people. SEUs happen there, and it's bad if you lose
the counter that has yourtime/position in orbit.
	
But it surprised me that even robust things like voltage
regulators are affected.
