A sextant helps navigators determine their position by measuring the angle between a celestial object, such as the sun or a star, and the horizon. By comparing this angle with known values, sailors can calculate their latitude and longitude accurately. This tool is essential for celestial navigation when GPS or other electronic systems are not available.

How did a sextant help navigators in the Exploration Ages?
A sextant was a crucial tool for navigators during the Age of Exploration, allowing them to measure the angle between celestial bodies and the horizon. By determining these angles, sailors could calculate their latitude and, with additional tools, their longitude. This capability significantly improved their ability to navigate open waters, leading to more accurate mapping of the world's oceans and coastlines. Ultimately, the sextant contributed to safer and more efficient sea voyages, facilitating exploration and trade.
How would having GPS technology have helped early navigators?
They wouldn't have had to depend on the stars for navigation. If the sky were cloudy, they wouldn't have been able to use a sextant. GPS and accurate maps would help them avoid obstacles.
What does a sextant help pilots and sailors do?
A sextant is an navigational instrument that helps pilots and sailors determine their position at sea by measuring the angle between a celestial body, such as the sun or stars, and the horizon. By using this angle, along with accurate timekeeping, navigators can calculate their latitude and longitude. This allows them to chart their course and navigate effectively, especially when GPS is unavailable.
What instruments are used to determine the altitude of the north star?
Instruments such as a sextant or a quadrant can be used to determine the altitude of the North Star. By measuring the angle between the North Star and the horizon, navigators can determine their latitude.
What is the purpose of the horizon shades on a sextant?
The horizon shades on a sextant are used to block out excess light from the sun or other bright sources on the horizon, making it easier to take accurate measurements of celestial objects such as stars or planets. They help to reduce glare and improve visibility when using the sextant for navigation or celestial observations.

What are two technological devices that helped navigators cross oceans?
The stars or a sextant or GPS or radar or sonar ( underwater)
How did the sextent help explorers?
The sextant helped explorers by allowing them to determine their latitude at sea by measuring the angle between the horizon and the sun or a star. This helped navigators plot their position on a map and accurately navigate the vast oceans.
How would having GPS technology have helped early navigators?
They wouldn't have had to depend on the stars for navigation. If the sky were cloudy, they wouldn't have been able to use a sextant. GPS and accurate maps would help them avoid obstacles.
What instrument aided explorers by allowing ship navigators to check their location by charting the position of stars and planets?
The sextant was the instrument that aided explorers by allowing ship navigators to determine their location by measuring the angles between celestial bodies, such as stars and planets, and the horizon. This device enabled navigators to calculate their latitude and longitude, which was essential for accurate navigation on the open sea. By using the sextant in conjunction with precise timekeeping, explorers could chart their positions more effectively and embark on longer voyages with greater confidence.
What tools did Ferdinand Magellan use on his voyage?
He was a sailor so he would use tools that the spanish or Portugal Navigators would use to repair the ships so he would use any tools to help get the sail boats out to sea.

What is the tool navigators used to find directions a long time ago?
Ancient mariners used tools called an astrolabe, a sextant, and a quadrant. These instruments were used in conjunction with celestial bodies, sunrises and sunsets.
What instrument is used to measure the altitude of the North Star?
To measure the altitude of the North Star (Polaris), an instrument called a sextant is commonly used. The sextant allows navigators to determine the angle between the horizon and the star, which corresponds to their latitude in the Northern Hemisphere. By measuring this angle, one can accurately ascertain their position relative to the North Star.
What map was created to help navigators?
the Mercator map
