To improve the accuracy, I would integrate several measurements. There
is no reason a sampled measurement at only one time needs to be made.

Hi:
Maybe this could be done with GPS or higher frequencies so the angular
resolution would be better?

Hi Anders:
That's something I've thought about for decades using an optical system. A few years ago I looked at it again and
found that astronomical "seeing" limits the accuracy. So the accuracy achieved by a spaceborne "Stellar compass" will
be much better than a ground based observation.
I don't think we could call it "amateur/semi-pro" but the millisecond
pulsar J0437-4715 would be perfect for this. Bright and precise.
Only for southern hemisphere people though.

out of curiosity, are there any amateur/semi-pro experiments that can
measure the length of the solar or sidereal day to sub-millisecond
resolution?
