Actually, GPS can still be used on floating island such as an oil tanker and cruise ships. All you need is a differential GPS to calibrate where is the floating island and its orientation. If an artificial island is built on grid, there is no need for GPS as the computer already know where you are from sensors in each street corner. A possible place where GPS is not usful is in an under- ground city. Heck, I got no GPS signal in concrete jungles like Seattle, Chicago or New York :)
