GPS is way too inaccurate--using commercial GPS (ie: a 3 satellite fix, the max allowed by the government), you would have a margin of error larger than the field itself.
Even with military GPS (5+ satellites), you'd still only be able to tell your position to about a meter or so.
Not to mention GPS is extremely cost prohibitive.
