Sextant
A sextant is a device used to determine a ship's latitude by measuring the angle between the horizon and the celestial body, typically the sun or a star. This information is then used in conjunction with nautical charts to calculate the ship's position on the Earth's surface.

Astrolabe
In the Southern Hemisphere, latitude can be determined using the angle of the sun at solar noon. Alternatively, you can use a GPS device or consult nautical charts that provide latitude information for navigational purposes. Additionally, celestial navigation using stars and other celestial bodies can also be used to determine latitude accurately.

The device used to determine the altitude of the North Star (Polaris) is called an astrolabe. An astrolabe is an ancient astronomical instrument that allows users to measure the angle of celestial objects above the horizon. By aligning the astrolabe with Polaris, one can determine their latitude based on the altitude of the star. This technique has been used for navigation and understanding one's position on Earth.
Ships are steered by a device called a rudder, which is operated from the helm.
The unit of measure used to determine absolute location is degrees and minutes of latitude and longitude. The Earth has 360 degrees at the equator.
