I will not be able to get a GPS signal where the test-equipment is
The best I am likely to be able to achieve is to keep the rubidium
locked to the GPS, then move the rubidium, whilst it remains powered
from internal batteries.
You do not always need the utmost in accuracy, and sometimes the
convenience of having a reasonably accurate internal reference is quite
If it's possible to 'see' sufficient satellites from an internal antenna
by a South facing window (latitude 51.5 deg N, longitude 0 deg), then it
might be practical to keep the equipment locked all the time.But I don't
know how practical that will be.
