Yes, very complex. No, you won't see it in something like a GPSDO. The effect you're talking about here is thousands to millions of times less than what you can measure. 12 hour or diurnal effects in a GPSDO are very common, but they are due to local temperature, GPS orbits, multipath, etc. /tvb _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
