- Definição1
- Equipment to determine the direction from which an electromagnetic signal is being generated. It can either be airborne or ground-based equipment. It operates in medium or low frequencies, consists of basically a loop aerial, and gives the null position of the transmitter. To remove 180º ambiguity, a sense aerial is used. The commonest air-interpreted ADF is one that utilizes a ground-based transmitting station called an NDB (nondirectional beacon).

- Definição2
- Electronic navigation equipment that operates in the low- and medium-frequency bands. Used in conjunction with the ground-based nondirectional beacon (NDB), the instrument displays the number of degrees clockwise from the nose of the aircraft to the station being received.
