Actually, WWV and WWVB are not worldwide in range. Military uses a system that is space based so they can see 12 satellites for a "fix" from anywhere on the globe they may need position.
But, there are effects to GPS signals if you are not using a 12 satellite solution, and thus, GPS quality at your receiver may depend on a number of factors. Higher quality GPS solutions come from the differential methods pioneered by our university laboratory. I am proud of my friends that developed the method to measure a bridge moving in the wind, for example.
