Benjamin Spratling Dissertation: Star-ND

The inspiration for our star tracker. Does not take into account star brightness, and uses a more complicated method for lookup table indexes which does not require knowledge of field of view size. This comes at the cost of a false positive rate that is an order of magnitude higher
