Automatic Direction Finder


Automatic Direction Finder (ADF) is a radio navigation system that provides aircraft with the direction of a ground-based radio transmitter. It operates by receiving signals from the transmitter and then using a directional antenna to determine the direction of the signal. The ADF can be used to navigate to a specific location or to track the course of an aircraft. It is particularly useful in areas where other navigation aids are not available or where the terrain makes it difficult to use other systems. ADFs can also be used in conjunction with other navigation systems, such as GPS, to provide redundancy and improve accuracy.
