Sounds like an interesting challenge. At least rtklib 2.4.0 was unable
to resolve the integer ambiguity problem (?) when I extended the
baseline to about 30 km.
Would be nice to know if this is due to my cheap antenna, finnish
weather, a problem in rtklib or something completely different. (Yes,
I did turn off all radio transmitters during the tests and ran from
battery power only).
