The difference here is that a drone will not be doing 2200mph over 3k miles so differences in the position of stars won't be particularly noticeable. You may be able to do some trickery with a few outward facing cameras and some software to map the horizon though.

Yeah, I'd trust it more as a source of direction than a magnetometer though.

Horizon tracking would be super cool. You'd have to open your cameras to blinding attacks again to make that work, but still. Even as a project unrelated to getting around jamming, that would be a neat piece of tech.
