GPS satellites systems are not your average DirectTV sats. They have more hardening and more backup. It would take at at least an EMP to take them out or direct targeting by anti-satellite weapons. Both not likely in a economic collapse.

The above said, I never travel without backup maps or my trusty compass.

Within the next few months (haven’t been keeping close track though) a bunch of comets are going to pass by, earth will likely or for sure be swept by some tails; many of which have asteroids and other stuff in them.

And funny thing is NASA not too long ago sent some kind of “be prepared” memo to employees. Junk passing by could potentially damage satellites. I would not count on GPS but would always have all kinds of reliable backout that I knew how to use.
