Vertical accuracy is worse. Mind you, that's the minimum. Some devices/locations reliably (95% of the time or better) can get 3 meter accuracy. For a technical document on that specification you can go here.

WebThe GPS satellites are the control points orbiting about 20,000 kilometers above the Earth. There's another difference; instead of there being three lines intersecting at the unknown point, there are four. Four are needed because there are four unknowns - X, Y, Z, and time - that need to be resolved.

WebGPS time is a precise time standard that is related to UTC. The major difference is that GPS time is a continuous time usually measured in weeks and seconds form the GPS time zero point of midnight, January 5, 1980. Controlled by UTC, GPS time is not corrected with leap seconds, and so is currently ahead of UTC by six seconds (1990).
