Question. As I understand it, you are trying to keep your oscillator OXCO stable as a function of what the GPS sig is reporting, then dividing that down for more resolution. If so, you are still at the mercy of what the GPS DO is reporting,. is this correct? The advantage is iF you don't see a sat, not likely, you still have a reference.
The OCXO is inherently stable. I need to tune it to the correct frequency. The PPS from the GPS has jitter. By integrating over many seconds, that jitter is reduced by the number of seconds of integration.

Fascinating project and series of videos. looking forward to more! Still need to watch 10 and 11.

@@davidskirmont8294 This is not a jitter. Every PPS pulse GPS module make a software correction of rising edge to move it precise to SAT atomic clock.
