Not really; amsat often uses COTS chips that aren't stable under
radiation, but which exhibit known (and reversable) failure modes.
SA1100 chips with cache disabled an
Space rated parts are necessary for standard duration space missions.
Short duration missions are different, as evidenced by many a CubeSat
that use pretty standard COTS parts. Rather than building a standard
duration satellite, I wonder what we can do to our current avionics
system to make it mor
