[FOSS-GPS] RTKLIB/RTKPOS RTK Static question

[Felipe G. Nievinski]

Both .pos output files show ns=8,
which is the number of G sat in both .15o input files,
so it seems the remaining four R sat are not being used.
make sure the .15g input GLO nav is being loaded.
also try enabling more logging info to debug
why rtkplot is not using the GLO sat obs.
