I'm using an uputronics GPS/RTC hat that has a u-blox M8 engine. I set it to stationary mode for extra accuracy. I'll have to look into other configuration options.

I'm currently trying to source PPS from software with this repo: https://github.com/twteamware/raspberrypi-ptp/blob/master/pp...

You might find this repo interesting.

I have a 500 MHz oscilloscope on hand so I can decently measure the offset between the raspberry pi PPS and GPS PPS.
