quadcopter navigation accuracy

Hi,
I'm very new so please bare with me :)
The questions below are for indoor (windows closed) & empty room (5X5 m' room) environment.
  1. Can a good (build or buy) quad-copter stay at the same height without moving at Z axis for more than 0.01 mm over time? (if not what best accuracy can be achieved?)
  2. Is it possible to move quad-copter in a given vector with minor deviations from the moving vector (lets assume we move very slow) - if so what deviations can be expected is it cm /mm/0.1mm /0.01mm scale?
What the hell do I want? well I'm thinking on building a small robot for very specific task & I would like to move in the direction of the markers & need high accuracy.
A robot with wheels will be less fan & I hoped to be able to play with quad-copter (but the high accuracy is a mast).
If an existing solution can be bought please direct me to it.

An accuracy of 0.01 mm is not realistic at all in a multi rotor aircraft. You should probably look into other concepts.
 
Thank you for your replay.
Could you kindly give a rough estimation that can be expected while keeping at same coordinates (it will have vibrations for sure but what are current standards for very stable) ?
 
Well, I'm still a newb at this, but I would think that if you could keep it within a 1ft (about 30 cm) radius for more than a few seconds you'd be doing really good. And that would take a lot of practice.

Unless I'm mistaken, the theoretical maximum accuracy of GPS is 2 meters.

Maybe someone with more experience will chime in.
