Abstract
A conversion system for a controller for an antenna rotator which includes circuitry for generating an analog signal which varies as a function of the angular position of the antenna. The conversion system includes circuitry for converting the analog signal to a corresponding first digital signal representative of the angular position of the antenna relative to a first reference heading of the antenna. The conversion system also includes storage circuitry having a prestored table of digital values of angular positions of the antenna relative to a second reference heading of the antenna and which in response to the first digital signal produces a second digital signal corresponding to one of the prestored digital values, the second digital signal thereby being representative of the angular position of the antenna relative to the second reference heading. A digital display system and controller for an antenna rotator are also disclosed.
