VHF Ground Stations

VHF Ground Stations, also known as Very High Frequency Ground Stations, are a critical component of the aviation communication system. These stations operate in the frequency range of 118.0 to 136.975 MHz and are primarily used for air-to-ground communication. They facilitate the transmission and reception of voice communication between aircraft and air traffic control (ATC) centers. The VHF ground stations are strategically located at airports, ATC centers, and other key locations to ensure seamless communication coverage over a specific geographical area. They are equipped with transmitters, receivers, and antennas that are designed to handle the high-frequency signals used in aviation communication. The signals from these stations are line-of-sight, meaning they travel in a straight line and the range is limited by the curvature of the Earth and the altitude of the aircraft. Therefore, the higher the aircraft, the greater the communication range. VHF ground stations play a vital role in maintaining the safety and efficiency of air travel by enabling continuous communication between pilots and air traffic controllers.
