I think I found the bug... The cameraTransform is set to camExtX, when it should be ExtCamX. Changing that fixed the problem for me. I'm guessing this came about from an errant grep Also, is it possible for the protractor functionality to be available always, even when the orbit does not make sense? Specifically for phase angle, it would be awesome to have a ground station to track transfer windows. I tried removing the check, it seemed to function alright.
