They're working on it however: http://www.extremetech.com/extreme/126843-think-gps-is-cool-...

Is GPS really that accurate, though, that it'll locate you with enough accuracy to allow a camera to center on your position?

If it is indeed using GPS, I'm guessing it's using a GPS in the camera base too, to figure out the correction.

Short-baseline differential GPS with a base station can have cm-level accuracy, if I remember correctly.

That's what I was thinking. Both are viewing the same satellites, since they're close to each other. The base, since it knows it's stationary, can derive the corrections itself, and figure out where the object is.
