Abstract
An automatic direction finding system for an airplane which utilizes ground equipment for automatically determining the line of position of aircraft transmitting radiant energy and which calculates the aircraft's line of position and transmits such line of position to the aircraft over an available audio channel. The ground station may be unmanned and provides for storage means for converting the aircraft's bearing from the station into an audible message which can be automatically transmitted to the aircraft.
