If you want to contact me off list I will share with you our low cost M12+

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 too much from the GPS 
system timing or
the M12+T  receiver?

Advice and comments  welcomed.

Thanks
Jerry
