Ground-based navigation

Ground-based navigation involves using terrestrial infrastructure, such as radio beacons, landmarks, or satellite signals from ground stations, to determine a vehicle’s or aircraft’s position and guide its movement. Unlike GPS, which relies on satellites, ground-based systems often use signals from fixed points on Earth to provide accurate location data. These systems are essential for air traffic control, maritime navigation, and certain military applications, ensuring safety and precision when satellite signals are unavailable or unreliable. They complement satellite navigation by offering alternative or backup means of positioning in environments like urban areas or remote locations.
