[teqc] Trimble RTX and teqc

Ok, what we've learned here is that the Trimble conversion is
including GPS L2C data and excluding GPS L2P(Y) pseudorange data compared
to the default teqc translation.  (However, the Trimble translation
must be including GPS L2P(Y) phase data because the RINEX L2 count
is non-zero for the GPS SVs where the RINEX C2 count is zero.
That's sort of odd ...)

However, you say that the teqc-produced RINEX in the RTX processing
is handling GPS ok, but not GLONASS.  For GLONASS, the big difference
is the lack of G1SA phase data in the teqc-produced RINEX.  This is
definitely not normal, but then again most of our GLONASS experience
from Trimble receivers is from the NetR9, not an R10 like you are
using.

I guess this will take looking at the raw data file from R10, which
you can email to me.  (Any short file will suffice.)
