Unless you plan to use the timing receiver for some other function, it really is overkill for the purpose of setting up an NTP server and otherwise also requires you to set up a proper antenna in order to benefit from the extra precision. > Am I overlooking something or missing interesting options? I think that setting up at least three "good enough" NTP stratum-1 servers in your network gets you much better synchronization than trying to get a single one more precise. To that end, you can set one up for around $60 if you use a raspberryPi and a NavSpark mini w/ patch antenna (if you have reasonable reception with that). You'll find that the NTP clients will not see any measurable improvement once you have the NTP servers down below 10µs deviation and it's possible to get each individual server consistently below 1µs with a bit of care. Having at least three stratum-1 in your network will keep the clients synchronized correctly when inevitably one of the servers will have the occasional problem that makes its time wander off for a while.
