Radio navigation aids are systems that help pilots and mariners determine their position and navigate safely. These aids use radio signals transmitted from ground stations to provide information about location, direction, and distance. Common types include VOR (VHF Omnidirectional Range) for aircraft and LORAN (Long Range Navigation) for ships. These systems enhance safety and efficiency in travel by allowing users to receive real-time data. They are essential for both commercial and private navigation, ensuring that vessels and aircraft can follow accurate routes and avoid obstacles. Radio navigation aids are crucial for modern transportation.
