Naval navigation is the process of planning and directing the movement of ships at sea. It involves using various tools and techniques to determine a vessel's position, course, and speed. Key methods include celestial navigation, which relies on the stars and celestial bodies, and electronic navigation systems like GPS, which provide real-time positioning data. Navigators use charts and maps to plot routes and avoid hazards such as reefs and shallow waters. They also monitor weather conditions and tides to ensure safe passage. Effective naval navigation is crucial for maritime safety and efficient shipping operations.
