Propulsion and navigation prototype systems are being delivered and before we got too far with the associated documentations I thought this would be a good time for a debate on the terminology we’re going to use for navigation.
There are two possible sources of tradition on this: navy and airforce. Space efforts were traditionally run by the airforces of the world and so that was the source of a lot of the terminology used in space. The vessels were small and maneuvers were tight, making them more like aircraft to fly (quite literally in the case of the Shuttle).
