I’ve been vibe coding a GPS stabilized PTP grandmaster / NTP server solution on a BeagleBone Black. Some optimizations I made to it today brought down the standard deviation of the pulse per second signal to around 10 ns. I think that’s about as good as I’m going to be able to do with this hardware.

It was a fun project that turns into being a rabbit hole about what defines time and the accuracy of it. Anyway, for my AES67 audio over IP work, this is more than fine to sync everything.
