The Automatic Direction Finder (ADF) is a radio navigation aid which provides :
-an indication of the relative bearing of the aircraft to a selected ground station (150 to 1799 KHz)
-aural identification of the ground station.
The frequency range includes :
-
the standard commercial broadcast AM stations (550 to 1610 KHz) located at known co-ordinates around the world
-
the Non-Directional Beacons (NDB) (190 to 550 KHz).

3. System Description
__________________
A. Principle The principle of the ADF navigation is to determine the relative bearing of a selected ground station. This is obtained by the combination of :
-
the signals from two loop and sense antennas positioned 90 deg. apart with
-
the signal from an omni-directional sense antenna. This signal is not
affected by the relative bearing. An external 96Hz signal modulates the composite signal which is processed in order to deliver the relative bearing. An additional Morse signal is provided to identify the selected ground station.
