By matching the star field around the Earth you can tell where you are over the Earth. While in earth orbit I had imagined that Declination and Sidereal Hour Angle and Distance from Earth could form the 3 axis for a 3 dimensional fix. But what are the references once you leave the earth behind? I guess the star field remains a (relative) constant, reference to the earth or the sun would be confusing because of their movement?
