Forget GPS.

You can't get the accuracy you need over the area you want for the money 
you've got. You would need to use differential GPS which will give you 
5-10 metre acuracy (convert to feet for the US). TO get more accurate 
positioning you need some fancy GPS recievers that look at the phase of 
the received GPS signal. They are used in surveying but are very expensive.

You could try some form of RF or IR doppler system, depeding on the 
environment.

Good luck......
