Communications and navigation on spacecraft rotating to create 'artificial gravity'

[KASASpace]

Well yes, that is how inertial navigation works! Pretty much every spacecraft and aircraft has done it that way for decades.

I think the OP was more curious about things like sighting stars, but I don't think that would a problem.

Well,

You could do what the Russian spy stations were going to do. You move the camera at the proper rate relative to the rotation.

The Russians would have a large camera that would rotate automatically to keep objects in site.

It was an Almaz, if I remember right.
