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.

Hello,
I am interested in getting an RTK GPS setup working for a moving
vehicle, not fast, perhaps 10 mph. I would postprocess the data
collected later, using data downloaded from a nearby station.
My desire is to log elevation data every few seconds as the vehicle
drives. I hope to achieve 10-20 cm accuracy for the position and the
elevation.
As I research RTKLIB, it seems like most information I come across is
regarding a static location. Is my goal feasible to achieve this kind
of accuracy as the vehicle moves?
If so, can anyone recommend a good board to get me started? I'm hoping
to be able to do this for under $200 (just one receiver since the base
station is public) -- please give me a reality check if this is
unlikely. Thanks,
Nick
