A navigator is a person or device that helps determine the position and course of a vehicle, such as a ship or an aircraft. Navigators use various tools and techniques, including maps, compasses, and GPS technology, to guide their journey and ensure they reach their destination safely. In modern times, navigation has become more advanced with the use of digital systems. Devices like smartphones and in-car navigation systems provide real-time directions and traffic updates. These technologies have made it easier for people to travel, whether they are using cars, boats, or airplanes.
