Electronic navigation

Electronic navigation is a way to find your location and go where you want using devices that run on electricity. It’s used by ships, airplanes, cars, and people, and it relies on sensors, computers, and screens to show where you are and where to go. Common methods include:

- Global Positioning System (GPS): satellites pinpoint your exact position.
- Inertial navigation: sensors track movement to determine location when signals are weak or unavailable.
- Electronic charts and digital maps: put your position and route on a map.
- Radar: detects nearby objects to help avoid collisions.
- Sonar or depth sounding: uses sound to map the water and find obstacles below.
- Radio navigation aids: signals from fixed stations help determine position.
- Automatic Identification System (AIS): shares your location and movements with others, mainly used by ships.

Organizations may combine these methods for more accurate navigation.
