A compass and a map of the world.
Navigational instrument or tool such as a sextant or astrolabe is used to measure the angle between a celestial body (sun or stars) and the horizon. This information helps determine the ship's position on a map by calculating latitude and longitude coordinates.
Aircraft and ships use GPS locators for precise positioning.
Thomas Edwards, was a pilot who invented the rotating airport light. It was in his funeral notice. He also was a NASA engineer. Ok, we have dispute my husband says he invented the rotating light for the planes.

During the Scientific Revolution, many ships wrecked due to a combination of navigational challenges and the limitations of contemporary maritime technology. Sailors often relied on inaccurate maps and rudimentary navigational tools, making it difficult to accurately determine position and course. Additionally, the era's increased exploration led to more ambitious voyages into uncharted waters, where hazards like reefs and storms posed significant risks. The lack of comprehensive weather forecasting further compounded these dangers, resulting in numerous shipwrecks.
An astrolobe which is an instrument that measured the position of the stars , and the magnetic compass helped determine the ships approximate location.
Navigational instruments aid in determining the speed, position and direction of a sea craft. Examples of these devices are chip logs, parallel rules, sounding lines, dividers and nautical almanacs.
There was no "captain" for the astrolabe. It was navigational tool used on the ships to guide them. The captain of the ship or the pilot used it.

Nautical and navigational terms, such as speed, velocity, and position, are fundamental in describing the motion of ships and boats at sea. These terms are interconnected with the principles of kinematics in physics, which study the motion of objects without considering the forces that cause the motion. Understanding nautical and navigational terms in the context of kinematics can help maritime professionals predict and analyze the motion of vessels for safe and efficient navigation.
