Optimum performance from a GPSDO requires two things: feed it with quality
inputs and keep disturbances to a minimum.
Use a very high quality antenna. My testing shows that the higher the quality
the antenna, the better the performance. A geodetic quality antenna is best,
a survey grade

And whether or not the gnat's ass is a part of his anatomy, by definition

OK.. just what is a gnat's ass in actual SI units?
It's small..

Know where the heck you are down to a gnats ass and get that location
into the unit with full accuracy. Errors in the saved antenna
position from its true position have a definite effect on the quality
of the output. Ideally have the antenna location surveyed in WGS84

Hello,
I am trying to achieve accuracy with two frequency standards disciplined to
GPS.
I am trying to get their 1 pps outputs close to each other as possible.
The idea being you put each unit in a different part of the world and the 1
pps outputs are sycronised.
So far I have two units
Hi
Depending on your antenna location(s) and GPS receivers, that's in the
good to very good range.
