I have a hard time visualizing that, a geometric representation for the reference frame and its transformation of the spin would help. But if I understand it correctly - wouldn't a gyroscope be able to determine that, in the case of Earth?
If you're in the reference system itself, I don't see how you would be able to tell without some outside comparison, which is kinda the point, right? I'm likely not imaginative and creative enough, and a gyroscope seems too easy an answer, TBH.
