[FOSS-GPS] RTKLIB Vehicle Accuracy

It does work in moving.  But signal problems do still make the position 
jump around, trees and buildings and an antenna's orientation changing 
can make an error happen.  Antenna quality has a lot to do with that, too.

RTKLib requires a GPS with RAW pseudorange outputs.  The NV08C is a 
good, cheap one to do it:


Contact your local sales rep there- it was actually easy in my 
experience to order a couple from them, and oddly cheaper than Newark 
element 14, as well as quicker to ship.
