As you know, a weak point of Wolfpacks was the constant radio communication, which was captured and triangulated by the enemies. Also, the U-boats has to transmit their communication every day at 6 a.m. (IIRC) When a mission is being executed, sometimes we need to send communication, as a ship sank, or convoy found. A …
WebThe basis of GPS is "triangulation" from satellites. To "triangulate," a GPS receiver measures distance using the travel time of radio signals. To measure travel time, GPS needs very … Direction finding (DF), or radio direction finding (RDF), is – in accordance with International Telecommunication Union (ITU) – defined as radio location that uses the reception of radio waves to determine the direction in which a radio station or an object is located. This can refer to radio or other forms of … See more Early mechanical systems The earliest experiments in RDF were carried out in 1888 when Heinrich Hertz discovered the directionality of an open loop of wire used as an antenna. When the antenna was aligned … See more Radio navigation Radio direction finding, radio direction finder, or RDF, was once the primary aviation navigational aid.
