Hi Mike, Rick's CNSC02-O1 implementation has been discussed here a number of times over the years (google the archives). It uses a programmable digital delay line to compensate for the receiver reported quantization error on each pending 1 pps.
Here's a quick plot of an M12+ receiver without (pink) and with (yellow) sawtooth correction: http://www.leapsecond.com/pages/gps4/cns-1pps.gif No, the correction doesn't handle for the case of prolonged "zero beat" errors.
