Well my surveyor BIL who pays $40k+ for GPS units is firmly of the
opinion that you can achieve this with 3 nokia phones and a bit of
averaging.  His fidding about with his phone (E72) has shown it to be
surprisingly accurate compared to his Mega-$$ surveying gear
especially if you are moving a bit. (ie: walking around the boundary
of a property)
