Hi:
Something I've been thinking about is attaching a large thermal mass of
aluminum to the crystal and it's oscillator then surrounding that with
insulation. Then surround that with a thin copper layer. Temperature sensors
on the copper and aluminum. If the thermal time constant could be made very
close to 24 hours, or integer multiples of that, it might be possible to
predict the inner temperature allowing compensation.
Has this already been done?
