Azimuth
Azimuth is the angle of an object around the horizon (measured from the North point, toward the East). It is usually measured in degrees.
| North | 0° or 360° |
| East | 90° |
| South | 180° |
| West | 270° |
In the horizontal coordinate system azimuth is one of the two coordinates. The other is altitude.
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.
