> However, did you ever tried to achieve 1-microsecond accuracy in your used refid (in your case with driver 28 which NTP uses)? My primary goal is to attain 1-microsecond accuracy bond where I can see 3 milliseconds offset with .GPS refid.
With driver 22 I am in the +- 10 usec range. With driver 28 in millisecond range.
See my blog.
I assume driver 20 is very similar to 28. Both are reading serial data.
I don't know if 1-microsecond is a easy goal. I am using a very cheap hardware. It's running on a BananaPI. All together about 150 EUR. With a good hardware it's maybe possible.
But why do you need this ? Is it just your ambition. This I could understand.
