Can anyone shed some light on why the GPS Cs beams have a worse stability
than the Rb vapor clocks?
I don't know, but it makes me wonder about things like
1) How sensitive is each to C-field tuning - i.e. for the same change in
C-field, by how much does each type change in relative frequency? (or
maybe it's exactly the same, I know nothing about the Zeeman effect) I'd
think there would be orbital changes in frequency, after all, it's
orbiting a big magnet.
2) How tight a lock can be obtained on each? i.e. might the physical
realizations of Rb clocks have a higher Q-factor?
