I'm a rank amateur on the time-nuts scale ... we did some replacements of
MTI OCXOs a few years ago, and folded all that info into a manual as we
built our own drop-in replacement OCXO modules for some XL Microwave and
SRS instruments.
It has some data on trim values for IsoTemp brand OCXOs, etc.
Hi
The most basic question is: how crazy do you want to go? This *is* TimeNuts so
crazy has very few limitations here …. :)
As mentioned in other posts, get to the point you have a clear view to the sky.
Ideally you want it clear to within 10 degrees of the horizon. You are concerned

Hi,
put the GNSS Ant. on the ground. If you use a magnetic antenna then use a smale
metal reflector on the bottom.
Than use only Sat’s with 30deg elevation (clear sky) After 24h your location 3D
Fix should be good for a proper 1PPS/ToD depends of your GNSS RX. Check DOP

I think there might be a down side to using more sensitive GNSS receivers,
which is
that such a receiver will be willing to include more impaired signals in
its time and/or
position solutions, leading to poorer overall accuracy.
Does anybody know?
I certainly concur that good antenna siting is

It's more complicated than just figuring out the error in the satellite's
clock. You also have to consider the error in the satellite orbit, the
difference between where you think it is and where it actually is.

Jeremy, thank you, especially for covering the 0-satellite case.
I wish stuff like this could be on a web page or FAQ or something, where it
was easily discoverable.
