For sailors, celestial navigation is a step up from dead reckoning. This technique uses the stars, moon, sun, and horizon to calculate position. Navigators using this method need a tool such as a sextant to measure the angle between objects in the sky and the horizon.Click to see full answer. Beside this, what did sailors use to navigate?Celestial navigation requires the sailor to use an instrument, like a sextant, to find the angle between a star/planet and the horizon. The angle will tell the sailor is latitude. The first compass was used in China about a thousand year ago and in Europe about 300 years later.One may also ask, who Discovered navigation by stars? Thomas Hubbard Sumner Similarly one may ask, how stars are used for navigation? Use pointer stars to help you find the North Star. The most commonly used pointer stars are Merak and Dubhe, the two stars on the edge of the Big Dipper opposite its handle. By following these stars in the direction of the Big Dipper’s mouth, you can find Polaris.How did sailors navigate in the Southern Hemisphere?The planet is spinning, and because the planet spins, the stars in the sky appear to rotate in a circle. In the Northern Hemisphere, there is a star, Polaris, that falls almost exactly at that point. In the Southern Hemisphere, there is nothing to mark the southern celestial pole.
