Does the Crustal motion affects the GPS position?

real time or over time?  I think the GPS position would remain constant, but you might need to get a map update from Garmin in a few thousand years to compensate for the 20m drift.

It is an interesting fact that approximately 200 million years, we will almost all be neighbors, or at least live on the same continent

Lars,
I found the same pic this morning looking for a rate of movement.

"Two hundred and fifty million years ago the landmasses of Earth were clustered into one supercontinent dubbed Pangea. As Yogi Berra might say, it looks like "deja vu all over again" as the present-day continents slowly converge during the next 250 million years to form another mega-continent: Pangea Ultima"
