[FOSS-GPS] Short moving baseline implementation

[Felipe G. Nievinski]

I'd have a third GPS as base station.
Then pick one of the two rover GPS
and process this first as kinematic
w.r.t. the fixed base station. Next,
process the second rover w.r.t. to
the first rover, with RTKLIB's "moving
base station" mode (it's _not_ w.r.t.
to the third, fixed GPS station).
Measure the constant baseline
length between the two rovers
and use that as a constraint
(there's a field for that in RTKLIB).
Make sure the uncertainty of it
is realistic -- tape measurements
won't be better than 1 cm, or 1 in
if the antenna phase centers are
not calibrated.  Keep the two rovers
as far apart as possible -- that will
improve the heading solution.
