USA HISTORY

Detailed explanation-1: -Sailors used new technologies to navigate across the world, including a device called the quadrant, a fan-shaped magnetic object that measured the altitude of stars, the moon, and the sun in order to determine the latitude of a ship.

Detailed explanation-2: -One instrument that can help to determine latitude is a sextant. A sextant is a navigational tool used to measure the angle that a celestial body, such as the sun, moon, or a star, makes with the horizon (Fig.

Detailed explanation-3: -Sailors such as Columbus and Magellan relied on this tool during their journeys across the oceans. The mariner’s astrolabe was an important navigational tool for finding latitude. It is a simplified version of the traditional astrolabe – an instrument that could help tell time, find altitude, and find latitude.

Detailed explanation-4: -Between 1100 CE and 1400 CE new technologies emerged which helped early sailors. The astrolabe helped sailors measure objects in the sky such as stars, planets, the moon and sun. After measurements were taken, the use of star charts then helped sailors to determine their location.

Detailed explanation-5: -During the Age of Discovery methods of navigation developed quickly because of the need of European explorers venturing to the New World discovered by Columbus in 1492. The instruments navigators used varied and included the quadrant, astrolabe, cross staff, hourglass, compass, map or nautical chart, and other devices.
