how about ANS (aka R2-D2) the 1960s version of GPS that used stars
instead of stars, preload all the known positions of LEO constellations
can they put this on a single chip 60 years later?

1. Use self contained "unit tests" or "dry runs" if you will for day to day scheduled or training purposes
2. Do precise (far fewer) "end to end" tests only where justified like for new hardware certification, never for shits and giggles
As the report pointed out, you can even have the tests stop if you can't fly without GPS (i.e you're unqualified to fly or your backup instruments have failed) by talking to ATC regardless.

There's a saying among medevac pilots when it comes to making go/no-go decisions: don't turn one tragedy into five.
Issue was on pilot training and the company that put 2 inexperienced pilot together.
