azimuth

The true bearing (between 0° and 360°) of a celestial body from the assumed position at the time of the sight. In a sight reduction (Workform, Boxes 5 and 6), it is obtained from applying the azimuth rules to the azimuth angle (Z). These rules are given on the Workforms and on each page of the sight reduction tables. See azimuth angle.

Azimuth is also used outside of celestial navigation as a general term for any true bearing.

"Azimuth ring" is a dumb compass used to measure relative bearings.
