*Azimuth- Azimuth is a mathematical concept defined as the angle, usually measured in degrees (°), between a reference plane and a point. This concept is used in many practical applications including navigation, astronomy, mapping, mining and artillery. The word azimuth is derived from the Arabic السمت ('as-sumūt'), derved from the Persian سمت ('samt') which means direction, referring to the ways or directions a person faces.

The more technical definition of Azimuth is:

'''''An arc of the horizon intercepted between the meridian of the place and a vertical circle passing through the center of any object; as, the azimuth of a star; the azimuth or bearing of a line surveying.'''''

OR 

'''''The quadrant of an azimuth circle.'''''

*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. 

*Course - In navigation, a course is the intended path of a vehicle. For space travel, it is the intended flight path of starship or the direction of a line drawn on a chart representing the intended path, expressed as the angle measured from a specific reference datum clockwise from 0° through 360° to the line.

*Heading - Heading is an expression of the direction a space vessel is traveling in relation to the center of the Galaxy. It is composed of two numbers: an azimuth (horizontal) value and an elevation (vertical) value, separated by the designator "mark". For example, a heading of 180 mark 0 would be a course heading to the outer rim of the galaxy, but on the same elevation as the center of the galaxy.

*Coordinates -Coordinates, also called galactic coordinates or spatial coordinates, are a set of numbers used to indicate a specific location on a planet's surface or point in space.

:'''''The galactic coordinates for the heart of the Milky Way Galaxy is 036 point 231. After the magnetic organism overtook the USS Enterprise, it demanded that the crew set the ship on course to those specific coordinates. (TAS: "Beyond the Farthest Star")'''''
