A system that automatically aligns and stabilizes off-gimbal electro-optical passive and active sensors of an electro-optical system. The alignment and stabilization system dynamically boresights and aligns one or more sensor input beams and an output beam of a laser using automatic closed loop feedback, a reference detector and stabilization mirror disposed on a gimbal, off-gimbal optical-reference sources and two alignment mirrors. Aligning the one or more sensors and laser to the on-gimbal reference detector is equivalent to having the sensors and laser mounted on the stabilized gimbal with the stabilization mirror providing a common optical path for enhanced stabilization of both the sensor and laser lines of sight.
