The word "azimuth" comes from the Arabic "as-sumut", which means "path", "direction". The most used phrases with the word azimuth are the azimuth of a heavenly body and the azimuth of an earthly object. Azimuth is the angle between the meridian passing through the point where the observer is located and the direction to a specific object. In practice, it is the angle between a local object, measured clockwise north in degrees, and north.

Step 1

Azimuths have the following classification: true or astronomical azimuth, geodetic azimuth, magnetic azimuth. Astronomical azimuth is the angle between the vertical plane passing through the star and the plane of the meridian. Geodetic azimuth is a dihedral angle that is counted clockwise to a normal plane that contains a given direction from the plane, its northern part, the geodesic meridian of a point. Magnetic azimuth is the angle between the plane of the magnetic meridian of place and any direction.

Step 2

In military topography, the order of movement in azimuths and the organization of the order of movement are practiced. The military bearing is the angle made by the heading north and the established heading. To walk in azimuth means to walk, guided by the compass and the calculated angle, that is, the azimuth, in a given direction. The essence of azimuth movement is the invariability of the direction on the ground, determined by the magnetic azimuths, and the distances marked on the map. Directions of movement are determined using a gyrocompass (a device for determining the angles of rotation of an object around the vertical axis and angles of course change) or a magnetic compass. Distances are measured using the speedometer or in steps.

Step 3

Auxiliary landmarks (except for intermediate landmarks) are often used to make it easier to maintain the direction of movement.

Direct azimuth is the azimuth from a certain point to another point. The return azimuth is the azimuth of a direction from another point to a specific point. These azimuths are called mutual azimuths.

Azimuths are calculated from zero degrees to a full circle on the compass degree scale, that is, from the north point - 0 degrees east to 360 degrees. In astronomy, the azimuth is calculated in the same direction from a point south to west. Azimuths are measured with goniometric instruments.
