Radionavigation
Radionavigation is a method of determining one's position and navigating by using radio signals. It involves sending and receiving signals from navigational aids such as satellites or ground stations. When a device receives these radio signals, it calculates the time it took for the signals to travel, allowing it to determine distances and pinpoint locations accurately. Common examples include GPS (Global Positioning System), which helps users find directions on smartphones or in vehicles, and maritime navigation systems that guide ships. Radionavigation is essential for air travel, marine navigation, and various outdoor activities.
