It’s curious that this doesn’t exist really. All the components are there, location via GPS, the tracking mechanics are not particularly difficult once you know the orientation, and there are good open plate solvers.

Maybe good sensors suddenly became cheaper? Willingness to put a real computer in the control system? For a long time even potato quality CCDs were expensive and handset electronics have been awful.

How hard would it be to do the opposite? point a camera at the stars in multiple directions, recognise the angle of various constellations, and use that to work out your location?
