Astro Compass

Astro Compass is a type of navigational instrument that falls under the supply class of Navigational Instruments in the supply group of Instruments And Laboratory Equipment.

An Astro Compass is used for celestial navigation, which involves determining the position and direction of a vessel or aircraft using celestial bodies such as the sun, moon, stars, and planets. It is particularly useful when other navigational aids, such as GPS or radar, are not available or unreliable.

The Astro Compass consists of a compass card that is marked with celestial bodies and their corresponding azimuths (angular measurements). By aligning the compass card with the observed celestial body, the navigator can determine the vessel or aircraft's heading or bearing.

Astro Compasses are typically designed to be portable and easy to use. They may have additional features such as a bubble level for ensuring accuracy, a magnifying lens for reading small markings, and a sighting device for aligning with celestial bodies.

Overall, Astro Compasses are valuable tools for navigators who need to determine their position and direction using celestial navigation techniques.
