Hello,
but you may need a firmware update for your GPS receiver to use a new
and very different coordinate system.

Less dramatically than a Uranus type axis shift event, the GPS needs
compensation for the earth axis shifting under the constellation. The
axis wobbles over a 24000 (or so) period. These effects can be lumped
into the precision ephemeris transmitted by each satellite.

Hello,
GPS may work in the far future only if there are still functional GPS
satellites and the GPS ground stations necessary for the orbit control
of the satellites. If the Earth would flip its poles, the satellites may
be destroyed in the time during the flip, when the earth magnetic field
is to weak for the Van Allen belts.

In real life (as opposed to crackpot fantasies)
a magnetic inversion willl typically take thousands of years.
So yes, the GPS sats will certainly be dead
long before it is complete,
