Given the way jump works, there's nothing to track. One moment the ship isn't there,
the next it is. That said, IMTU you can make educated guesses as to where a ship came
from, based on such things as where on a 100 diameter jump limit it emerged, what
kind of ship it is, and sometimes on its vector.
