What navigational device used at sea?

One commonly used navigational device at sea is the Global Positioning System (GPS). It utilizes a network of satellites to provide accurate location data, allowing sailors to determine their precise position on the Earth's surface. Other traditional navigational tools include the compass, which helps establish direction, and the sextant, used for measuring angles between celestial objects and the horizon to determine latitude and longitude. Together, these devices enhance safety and efficiency in maritime navigation.
