A component of an electronic navigation system that follows and remains in the center of a doppler frequency or frequency chain spectrum. Its output signal is used in applications, such as antenna steering through an associated servo loop, and for the display of drift angle and ground speed. See also computer (1)-frequency tracker, air navigation.
