What Is A Sextant?

A sextant is a navigational instrument used in marine navigation and astronomy to measure the angle between two objects, typically the horizon and a celestial body such as the sun, moon, or stars. It is an essential tool for sailors and navigators to determine their position at sea by measuring the angle of celestial bodies above the horizon.

How To Use A Sextant?

1. Aligning with the Horizon: The sextant has a small telescope and a sighting mechanism. To use the sextant, a navigator aligns the instrument with the horizon and the celestial body they want to measure.

2. Adjusting the Index Arm: The index arm of the sextant is then adjusted until the image of the celestial body is reflected in a movable mirror or half-silvered glass. The navigator continues adjusting until the body's image coincides with the horizon.

3. Reading the Angle: The angle is then read from the scale on the sextant. This angle, combined with the time of observation, can be used to calculate the observer's position.

What Is A Sextant Used For?

A sextant is primarily used for celestial navigation, a technique that relies on the observation of celestial bodies to determine a vessel's position. This is particularly useful when other navigation methods, such as dead reckoning or GPS, are not available or reliable.

Who Invented The Sextant?

The sextant as a navigational instrument has a long history. It evolved from earlier navigational tools, and its modern design can be attributed to several inventors. However, the practical and widely adopted sextant is often associated with the work of John Hadley and Thomas Godfrey. In the early 18th century, both independently developed similar octant-like instruments that laid the foundation for the modern sextant. Hadley is credited with introducing the design improvements that eventually led to the widespread use of the sextant in navigation.
