FIELD: physics.
SUBSTANCE: outer frame of a device for stabilising the line of vision is fitted with an inner frame whose axis of rotation which is perpendicular to the axis of rotation of the outer frame. The inner frame is fitted with a movable mirror whose axis of rotation coincides with the axis of rotation of the outer frame in the initial state. A system of three mirrors is mounted on the outer frame. First, second and third motors are mounted on axes of rotation of the outer frame, the inner frame and the movable mirror. First and second angle sensors are mounted on the axes of rotation of the inner frame and the movable mirror. Three angular velocity sensors are mounted on the back side of the movable mirror. Inputs of the motors are connected to outputs of amplification-compensating devices.
EFFECT: stabilisation of the line of vision at elevation guidance angles ranging from 0 to 180 degrees.
