Azimuth

Azimuth is the direction, in degrees, referenced to true north.

In celestial navigation, the position of a celestial body is described by its azimuth and elevation above the horizon. In radio astronomy azimuth refers to the position that an antenna must be pointed to receive a satellite signal (compass direction). In aviation azimuth is used to determine headings or the direction in which to fly. The angular distance is measured in a clockwise direction.
