[gpsd-users] Using a known location instead of WAAS/GLONASS/RTK/... for corrections

[Jobs, Steve]

Is it possible to pass a know location to gpsd and have it use that for 
error correction?  I may be asking this question wrong so allow me setup 
the scenario.  I have two matching receivers, in this case LS20031, one 
of which will be a base station and the other will be on a rover.  Both 
will be running their own instances of gpsd.  The rover will never 
travel more that 400 feet from the base station so they should almost 
always be sharing the same satellites.  If I place the base station at a 
known location can I just find the difference between the signal and the 
known location and pass that to the rover as the correction? Or even 
better would be to have the base gpsd take the known position and then 
the rover could query the base gpsd for the correction and apply it to 
the signal it has received from its own gps receiver.
