The term 'Azimuth' in navigation specifically refers to the true bearing to a celestial body, such as a star, from the observer's position. It is defined as the angle measured in degrees from a reference direction, typically true north, around the observer's horizon. This measurement is crucial for navigators as it allows them to determine the direction in which they need to travel or align their vessel based on the position of celestial bodies.

The use of azimuth is fundamental in celestial navigation, where navigators rely on the positions of stars and other celestial objects to ascertain their location on Earth. The ability to calculate an accurate azimuth helps ensure that navigators can effectively chart their course, especially in open waters where land-based references are unavailable. Thus, understanding azimuth is essential for any mariner seeking to navigate using celestial bodies.
