An Automatic Direction Finder (ADF) is a navigation instrument that automatically and continuously displays the magnetic bearing from an aircraft or vessel to a selected radio beacon, typically a Non-Directional Beacon (NDB). It works by detecting radio signals using a combination of loop and sense antennas, processing the phase difference between these signals to determine the direction of the transmitting station relative to the vehicle's heading. The bearing is then displayed on an indicator, providing crucial directional guidance to the operator.
Despite the prevalence of GPS and other satellite navigation systems, ADFs remain highly relevant due to their independence from satellite signals. They provide a reliable, terrestrial-based backup navigation source that is immune to GPS jamming, spoofing, or outages. This resilience is critical for safety-of-flight and maritime operations, especially in remote areas or challenging environments. Many instrument approach procedures still utilize NDBs, and ADFs are essential for navigating to these facilities or locating distress beacons.
The primary differences between analog and digital ADF systems lie in their signal processing capabilities, accuracy, and integration.
