Cách sử dụng
A sextant is a tool used for navigation by sailors and pilots. It helps them determine their position by measuring the angle between the horizon and a celestial object, such as the sun or stars. This is done by looking through the scope of the sextant and aligning it with the object being observed. The angle is then used to calculate the position of the vessel or aircraft. Sextants are not commonly used today, as technology has provided more accurate and efficient navigation tools. However, they still have value in situations where technology fails or is unavailable.
