Bearing measurement by phase comparison method.
A radio navigational aid operating in the UHF (ultrahigh frequency) band that provides information about the slant range and the bearing from the station. It is used generally by the military. The aircraft equipment interrogates the ground transponder and obtains the slant range by measuring the time difference and the magnetic bearing to the aircraft. It does this by modulating the pulses being transmitted by the beacon. Since the ground beacon is continuously on, the bearing and range information is continuously available. TACAN equipment also permits an aircraft to find its range from another aircraft also equipped with TACAN and operating at a fixed differential frequency. The frequency selection is by a preset channel number (1 to 126). On aeronautical charts, TACAN is shown by the symbol image
