Hi
So it's a pretty good AT cut crystal without any compensation of heating. Not
quite a cheap wrist watch, but not a BVA in a dewar flask either.
The environmental perturbations should go quite slow most of the time,
as it glides in the void slowly away and often have a fairly stable
direction with regards to the sun. If they have spin-rotation it
complicates things a bit.
Decent dewar-flask with better background radiation and one major heat
source that you track for the solar panels.
Yeah, there's jokes about why are they obsessing about hermetic seals on
components when we're going to be operating in a harder vacuum than you
can easily achieve on earth. The outside of the package probably has a
lower pressure than inside the package.
