This is a pretty old/widely used technique. Here's a paper about it from 1999, implementing on a DOS PC.

The really interesting stuff more recently is using RTK software to get accuracy on the order of 10s of cm with cheap GPS receivers.

RTK stands for Real Time Kinematics, for those who (like me) wondered.

Yes, that's is. This is not unique solution. We collected all information in one article and described what we did.

With some hackery you can get an RTKLIB compatible GPS for as low as $30, but one should expect to pay no less than $200-$400 for a ready made solution with an useable antenna. Costs go up fast from there.
