Electronic navigation aids

Electronic navigation aids are electronic systems used by ships, aircraft, and vehicles to determine their position, direction, and proximity to obstacles. They include devices like GPS (Global Positioning System), radar, and radio beacons, which send and receive signals to help travelers navigate safely and accurately. These systems enhance safety, improve route planning, and reduce the risks associated with human error or poor visibility. By providing real-time location data and guidance, electronic navigation aids ensure efficient and reliable travel across land, sea, and air.
