[teqc] QC for IRNSS data

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.
