What is an azimuth used for in navigation?

An azimuth is specifically utilized in navigation to determine direction. It is defined as the angle between a reference direction (usually true north) and the line of sight to a target or waypoint, measured clockwise from the north. This angle is typically expressed in degrees, ranging from 0° to 360°.

In practical applications, using an azimuth helps navigators pinpoint their position relative to specific landmarks or destinations. This capability is essential for accurate navigation in various settings, whether it be during outdoor activities, military operations, or while using navigational instruments in aircraft and ships.

The other aspects mentioned—measuring distance, estimating speed, and calculating altitude—are practices that involve different techniques or tools and are not related to the function of an azimuth. Hence, determining direction is the sole purpose of using an azimuth in navigation.
