az·i·muth

 (ăz′ə-məth)
n.
1. The horizontal angular distance from a reference direction, usually the northern point of the horizon, to the point where a vertical circle through a celestial body intersects the horizon, usually measured clockwise. Sometimes the southern point is used as the reference direction, and the measurement is made clockwise through 360°.
2. The horizontal angle of an observer's bearing, measured clockwise from a reference direction such as true north.
3. The horizontal angle of a projectile's motion, measured relative to a reference direction such as true north.

[Middle English azimut, from Old French, from Arabic as-sumūt, pl. of as-samt, the way, compass bearing : al-, the + samt, way (from Latin sēmita, path; see mei- in Indo-European roots).]

az•i•muth

(ˈæz ə məθ)

n.
1. the arc of the horizon measured clockwise from the south point, in astronomy, or from the north point, in navigation, to the point where a vertical circle through a given heavenly body intersects the horizon.
2. (in surveying) the angle of horizontal deviation, measured clockwise, of a bearing from a standard direction, as from north or south.

az·i·muth

(ăz′ə-məth)
The horizontal angle measured clockwise between a celestial object and the northern point of the horizon as seen by the observer. Azimuth and altitude are the coordinates used to navigate with respect to the stars.

azimuth

Quantities may be expressed in positive quantities increasing in a clockwise direction, or in X, Y coordinates where south and west are negative. They may be referenced to true north or magnetic north depending on the particular weapon system used.
