[time-nuts] Nav Receiver Sawtooth Correction?

I've gotten my PLL mostly working, but, since I'm using a nav receiver, it looks like I may want to see if I can do a poor-man's sawtooth correction based on GPS position changes. Has anyone done this or have a reference for a project that has? It would seem to me that only the East-West movements would be a factor, but I dunno. As a beginning, I was just going to plot lat and lon deltas from "gpsd" data to see what correlates to the phase error jumps I'm seeing, unless this path has already been tread. I don't expect the accuracy that would be afforded by a real timing receiver.
