Bearing

Bearing is a description of the direction of a space vessel in relation to another object, such as a planet, star, starbase or other object in relation to the forward direction of travel and is usually accompanied by a distance measurement. An object on a bearing of 090 mark 270 is to the starboard and below the vessel; an object bearing 300 mark 10 is located to the port side of the vessel and above the current plane of travel.
