[teqc] QC for IRNSS data

Yes, the 3.03 rinex contains c9 observations.
I will try down converting the rinex file but I understand that it cannot
include S-signal data. But I will just check how the QC output will be for
single frequency for experimental purpose.

Thanks.

Technically, teqc can read any RINEX version prior to and including 2.11,
including
very old RINEX version 1.

And in down-converting any RINEX 3.xx to 2.11 (using the tools suggested by
John,
or any others), you'll need to consult the tables in
https://postal.unavco.org/pipermail/teqc/2018/002475.html

For IRNSS, note that only observables for the L5 signal has been added to
the extended
RINEX 2.11 in teqc -- so any IRNSS S-signal observables (C9* in RINEX 3.03;
see p. 24
of ftp://igs.org/pub/data/format/rinex303.pdf) cannot be represented in the
extended
RINEX 2.11.  (Then again, does your RINEX 3.03 file even have IRNSS C9
observables?)

With only IRNSS L5 observables in the extended RINEX 2.11, I doubt you are
going
to get the type of qc analysis you are expecting because the analysis will
be
single-frequency only.
