I even think that a GPS has become an important part of celestial navigation. I call it my AP indicator. :-)
Since GPS is a single source, I don't take it's data as true until I confirm it through something trustworthy like a celestial shot. I'm not sure if this GPS technology is always working, but the moon and stars are pretty reliable.
