The physics package in a CSAC is a vacuum, so it probably won't make
But, as a practical matter, I have a system with a CSAC going through
thermal vacuum testing as I write this. We'll get some test data and we
can compare the frequency against GPS and a OCXO at room temp/pressure,
and at various temps in vacuum.
Remind me in 2 weeks, and I should have the data plotted.
