Bertrand Zauhar, VE2ZAZ updated his design (technology marches on),
since the 2006 QEX article.

“A Modernized GPS-Derived 10 MHz Frequency Standard” (2024)
https://ve2zaz.net/GPS_Std_Modernized/GPS_Std.htm

Construction of the new board uses Surface Mount components with
32-bit STM32 (Black or Blue Pill); uBlox based GPS receiver;
10 MHz OCXO; and 20-character, 4-line LCD display.

I acquired the board and built the implementation from the attached QEX article.
It seems to work.
I know it has been discussed on this board quite a bit and has its faults.
