Abstract
Abstract A disturbance compensation system for a camera on board a spacecraft and having an imaging device and condensing means for condensing light onto the imaging device. Linear actuators adjust the position of the imaging device by moving it with multifreedom. A control circuit computes, in response to position information associated with the imaging device, an amount in which the position of the imaging device should be corrected, and controls the linear actuators on the basis of the computed amount.
