Abstract
A control system for radiation tracking apparatus comprises: PA0 (a) photo sensors to receive incident radiation, PA0 (b) edge means to intercept radiation directed toward each sensor so that primary and secondary locations on each sensor respectively receive and do not receive incident radiation, the sensors controlling tracking movement of the apparatus, PA0 (c) the sensors being electrically energized and having electrical outputs which vary a function of radiation interception by the sensors, and there being means responsive to said outputs to control said tracking movement, PA0 (d) and there being control means connected with the sensors and responsive to increases and decreases in the intensity of said radiation to respectively decrease and increase electrical energization of the sensors.
