That file, from gpsrinex is in RINEX 3.05 format.

That file is in the older RINEX 2.11 format, does not include the
Doppler measurements, and uses the older names fo r C1C, L1C, C2C and
L2C.  RTKLIB has not been updated in a long time.

I can't really compare them as they are observations from two different
times.

The gpsrinex:

> 2023 04 11 11 18 00.0010000  0 13

And the RTKLIB:

 23  4 25  8 13  8.0040000  0 31G12E12G11G06E03S36R10R02R22R12R01G22

The RTKLIB is from 14 days later, so I can't comparte the outputs, even
if I could untanlge the 2.11 versus 3.05 differences.

Also the gpsrinex has L2 data, but the RTKLIB does not.  Most PPP services
will not work without the L2 data.
