Navigation instruments are tools used to determine the position and direction of a vehicle, whether on land, sea, or in the air. Common examples include compasses, which show magnetic north, and GPS devices, which use satellites to provide precise location information. These instruments help travelers and navigators find their way and ensure safe journeys. In addition to compasses and GPS, other navigation instruments include sextants, used for celestial navigation, and altimeters, which measure altitude. Charts and maps are also essential for visual navigation, providing detailed information about terrain and routes. Together, these tools enhance navigation accuracy and efficiency.
