As far as I am aware of, that is the current state.
The GPS/Galileo was signed slightly before that thesis, IIRC.
The L2C and L5C signals are "old-school" LFSR generated PSRN BPSK
signals. The only "special" signals are L1C, E1 OS and E5.

QZSS uses GPS L1 C/A signals, IIRC
Beidu and IRNS I don't know.

If I am not mistaken, navipedia is up to date with everything,
but I have not read everything, nor checked against the standards
what I have read there.

It is upon moral qualities that a society is ultimately founded. All 
the prosperity and technological sophistication in the world is of no 
use without that foundation.
