Well, if you want to go the DIY way and build everything yourself,
then have a look at [1], where I collected most of the available
GPSDO designs (There are a few missing, but nothing substantial).
I would personally go the way that Nick Sayer took. It is closest
to how I would build a GPSDO. Maybe use a TIC7200 as interpolator
like Tobias Pluess did a couple of months/years ago.

There are a lot of discussion on the time-nut mailinglist on how
to do this or that. I would especially look for the discussions
with Tobias Pluess around 2019/2020. There were some good ideas
passed around in those. But there are plent of others as well.
Just look at the archives and search for GPSDO and you will find plenty.
