A target seeking device having a gyro rotor rotating about its axis with two degrees of freedom about a central point of rotation. The device includes a detector fixed with respect to the housing of the device, an optical system by which the field of view of the device is imaged in the plane of the detector, means for producing relative motion between the field of view image and the detector, a signal evaluating circuit, means for producing precession motion of the gyro rotor, and position sensors which respond to the angular position of the gyro rotor relative to the housing. A torquer is provided for receipt of scanning signals. The signals of the position sensors are applied to the torquer through a feedback loop. An evaluation circuit is provided for producing follow-up signals from the detector signals and the position sensor signals.
