[GRLUG] OT, but GPS, anyone?

[L. V. Lammert]

Got a project where we need to establish a true N indiation on a
stationary piece of equipment using a Linux host, .. if we had two GPS
units, say, 25' apart it would be trivial (take the differential between
the two readings and any positional errors cancel, producing a reference
vector that can then be corrected to true N).

Need to determine the *minimum* spacing between two units - don't
suppose anyone knows anything about this sort of technology, or could
point us in the right direction?

	TIA,

	Lee
