I used this board from Uputronics[0] with optionally included active GPS antenna. Mostly because they were readily available, and there were few guides online for setting ntpd up on Pi using Uputronics board. As a word of caution - it looks like most guides that I came across are outdated, or indeed have never produced a reliably (or at all) working NTPd setup. Instructions that lead me to the 'right' path is linked here[1]. I am still in the process of tuning GPS offset in my setup. But all in all, it's been a great learning experience into complexities of the protocol I've mostly taken for granted for a very long time.
