Re: Computer?

Indeed, automated star trackers have been used on spacecraft for years.

You suggestion of using radio frequencies to pinpoint stars is an interesting one. Off the top of my head the problem would probably be that the antenna required for radio astronomy would be fairly large, but then boats can be very big. And it wouldn't just work through cloud, you can do radio astronomy all day as well.
