If you want to contact me off list I will share with you our low cost M12+
saw tooth correction circuit.

OK, so before I commit to my Sawtooth correction design, I had a thought about
adding
additional filtering to the sawtooth corrections using a Kalman filter.
The Kalman filter would be driven using the @@Hn data coming from the M12+T
reciever.
Is this something worth doing or am I expecting
To use the Kalman filtering technique you need a model of the sawtooth
error... the model of the error is simply the quantization of the UTC PPS
done by the M12 clock, so I think that in the sawtooth correction output by
the M12 you have already all you need.

As long as you're playing with @@Hn messages, Kalman filters,
and software sawtooth correction, you might want to consider
looking at the per-SV fractional GPS local time estimates in the
Hn message. It's the mean of these
