Azimuth Circle

Azimuth Circle is a navigational instrument that falls under the supply class of Navigational Instruments in the supply group of Instruments and Laboratory Equipment.

An azimuth circle is used in navigation to measure the azimuth or bearing of a celestial body, such as the sun or a star, relative to the observer's position. It consists of a circular scale graduated in degrees, with a sighting device or telescope mounted at the center. The observer aligns the telescope with the celestial body and reads the azimuth angle from the scale.

Azimuth circles are commonly used in marine navigation, especially for celestial navigation. They are also used in land surveying and other applications where accurate measurement of azimuth angles is required.

In the supply group of Instruments and Laboratory Equipment, azimuth circles are categorized as navigational instruments because of their specific use in navigation and positioning. They are essential tools for determining the direction and bearing of celestial bodies, which helps in determining the ship's position and course.

Overall, azimuth circles are important instruments in the field of navigation and play a crucial role in ensuring accurate positioning and course determination for ships and other vessels.
