A device for target tracking, with a frame (1) intended to be supported against an operator's shoulders shows a two-axis platform, that is a platform which is pivoted in azimuth and elevation, controlled by a first and a second motor (6). The platform carries an aiming means such as field-glasses (7), and is primarily characterized in that the platform is provided with two angular rate sensing gyros (8), each of which in a closed servo circuit of its own acts on said motors to aiming-stabilize the platform in space, whereby the aiming of the platform is insulated from external disturbances via the frame. |
