Not completely ignorant. He described the plot of coverage as a
"mouse bite" taken out of the North. That implies to me that he is
not way up there in high latitudes as is even southern Sweden. As
you move south there is no "hole" or more precisely you can't even see
to the center of the hole

Hi
If everything in the plant gives the same answer - do you actually care if
you are 0.5 ppm off? In a lot of cases the answer turns out to be no,
provided the drift rate is very low.
I wish that were the case, but things are far enough off that it's a problem.

The 24 GPS satellites are in orbits that never pass over the poles.
I think they are about 60 degree inclinations. By your description
you must be in the northern hemisphere. If you can, set up your
antenna so it can see to the south and
or the purpose will do
a better job than something you lash up.

I have a thunderbolt up and running since last week Friday.
I'm doing this for a calibration source at work, eventually we will have two

below 30 degrees or so.
