Sounds like the study of movement outside of the gravitational attraction of planets and such... when we launch vessels into orbit, there are orbital maneuvers we use within Earth's gravitational field; for instance, when the manned Gemini capsules were en route to rendezvous with their Agena targets, the Geminis would approach from below, at a faster speed, then boost their orbit as needed for the rendezvous.
Outside the gravitational field of Earth, this maneuver would've been exercised in a complete different matter. Sounds like this may be the point of the subject...? Again - guessing.
Edit: Hmmmm.... then, maybe it's a very local focus on maneuvering in space (instead of figuring out how to get from North America to Europe, it's instead how to move your ship 14 feet to the left, and up 2 feet...)
Heck, that sounds like a class I'd like to take just to figure out what the title means....
