Ionosphere
The ionosphere is a layer of the Earth's atmosphere that is ionized by solar and cosmic radiation. It is located between 60 and 1000 km above the Earth's surface and is responsible for reflecting radio waves back to the ground. The ionosphere is divided into several layers, each with different ionization levels and properties that affect radio communication and navigation. The ionosphere plays a crucial role in aviation as it affects the accuracy of radio navigation systems and communication between aircraft and ground stations. Pilots must take into account the ionosphere's effects on radio signals when planning their routes and communicating with air traffic control.
