Don't they need more than 1 star to get an orientation? I mean other than brightness 1 star doesn't give you a lot of information?

  I guess if they can confirm that it is a specific star they know where on a I finite line they are. If that line happens to be through earth and the space craft they know where to point their antenna.

  Yes, I think the tracker also uses the sun as I remember reading.
