Abstract:
A device for stabilizing of a remotely controlled sensor, comprising:a sensor provided with a two-axes yaw and pitch stabilizing self-acting rategyro, which sensor is provided as a first gimbal, turnable around a first yaw axis, journalled in an inner, second gimbal;said second gimbal being in turn turnable around a first pitch axis, and being journalled in an outer third gimbal, turnable around a second pitch axis;said third gimbal being journalled in a fourth gimbal, turnable around a second yaw axis;a first set motor being provided, fastened to the fourth gimbal, acting upon the second pitch axis;a second set motor being provided fastened to a stand fastened to a vehicle, acting upon the second yaw axis;a first rategyro being fastened to the stand for sensing of the yaw angle rate;a second rategyro being fastened to the fourth gimbal for sensing of the pitch angle rate;an electronic unit being provided acting, under the influence of signals from the first and second rategyro via the first and second set motor, to stabilize the third gimbal and the fourth gimbal;the set motors being acted upon via the electronic unit for controlling of the sensor in pitch and yaw; anda mechanical coupling, comprising a resilient coupling means, connecting the first gimbal to the third gimbal.
