The primary use of a sextant is to measure the angle between an astronomical object and the horizon for the purposes of celestial navigation The estimation of this angle, the altitude, is known as sighting or shooting the object, or taking a sight The sextant on the other hand was made specifically for navigation and is a more accurate instrument that allows the users to find both latitude and longitude It works on a reflection principle and is easier to use compared to the astrolabe. Practice makes perfect when it comes to using a sextant for navigation says ivar dedekam, author of illustrated navigation A sextant is an optical instrument used in navigation to measure the angular distance between two visible objects, most commonly a celestial body and the horizon
This measurement, known as a “sight,” allows navigators to determine their position Historically, sextants played a significant role in precise oceanic exploration and trade for centuries Even with modern satellite navigation. Celestial navigation is an ancient art that still holds immense value for sailors today Discover the importance of using a sextant for accurate navigation in open waters.
