The present invention provides a search and tracking device. The device has a tracking receiver and a working mode and direction control device. The optical system is used to monitor the direction in which radiant energy is incident upon the system. The infrared energy is input to the receiver by the optical system, which responds to this and generates a position error signal indicative of the deviation of the infrared energy from the optical axis of the optical system, mode of operation and direction control The optical system is aligned according to the search signal in the search state (before the tracking receiver receives the infrared energy)
