Hi
As explained to me, the corrections result in an improvement in location and
that’s is their
objective. They don’t care about any time error they might generate part of the
correction
process. You could call this sloppy math. Without a time reference in their
system, they
don’t have

I have never seen any manufacturer recommend SBAS for improved timing. The
simple answer seems to be that the reference system does not have time sources
in it and that the software that generates the corrections does not consider
time to
be important.

And they may well be correct about it.
The optimal position-hold position is the one which gives the smallest

SBAS (or WAAS or whatever) will
When the PPS is generated by the internal free running oscillator,
there is nothing to do: the sawtooth correction must be considered.
The augmentation service will provide a better sawtooth estimate and a
better position estimate as well.

I’m sure it’s probably receiver specific. I know the M8 series of UBlox
specifically say to disable SBAS for timing purposes. Not sure about the
Novatel.

I'm wondering if GPS augmentation services improve a receiver's 1pps
output? My specific interest is with the Novatel OEM6 series of
receivers (but this issue is applicable to other receiver types as
well). With this receiver an external 10MHz oscillator can be steered
by the GPS receiver, so
