Math and computer science would be the underpinning as everything is based on math and you would use the computers to project celestial movements.  Physics, astrophysics and astronomy would be the more specialized courses.  Starship navigation since the most common use is to guide ships through the galaxy.  Then finally Stellar Cartography would be the specialization in how to take your knowledge to make the maps used in the ship's computer and navigation.
