Navigators are individuals or tools that help determine the position and course of a vehicle, such as a ship or an aircraft. They use various methods, including maps, compasses, and modern technology like GPS, to guide their journey and ensure safe travel from one location to another. In maritime contexts, navigators often rely on celestial navigation, which involves observing the stars and planets. In aviation, they may use flight plans and radar systems. Both types of navigators play a crucial role in ensuring that transportation is efficient and safe, whether on water or in the air.
