To view the original source information, use the "Learn more" links.The ADF/NDB navigation system is one of the oldest air navigation systems still in use today. It works from the most simple radio navigation concept: a ground-based radio transmitter (the NDB) sends an omnidirectional signal to an aircraft loop antenna.www.liveabout.com/the-adf-ndb-navigation-system …Automatic direction finder (ADF) equipment points to the direction of an NDB. NDB navigation consists of two parts — the automatic direction finder (ADF) equipment on the aircraft that detects an NDB's signal, and the NDB transmitter.en.wikipedia.org/wiki/Non-directional_beaconBased on simple AM-radio ground stations called NDBs (non-directional beacons), an ADF is an aircraft instrument with a directional arrow-shaped pointer. The arrow simply points straight at the programmed NDB’s position in relation to the aircraft.aerocorner.com/blog/automatic-direction-finder/The non-directional beacon and its associated automatic direction finding equipment is primarily a short distance navigational aid. The ground station (NDB) radiates a signal in all directions around the transmitter, and the aircraft receiver (ADF), when tuned to this signal determines the direction from which the signal is being radiated.www.casa.gov.au/sites/default/files/2021-09/operat…The ADF (Automatic Direction Finder) is the receiver of the NDB’s transmissions. The NDB (Nondirectional Radio Beacon) is the transmitting antenna on the ground. Operates in the L/F, M/F range between 190 & 1750 KHZ.www.studyflight.com/adf/
