The paper deals with the influence of control system of a mobile free-space optical (FSO) link on the power budget of the link. Permissible fluctuations of the received power are taken into consideration. It is assumed that these fluctuations are caused by oscillations of the optical beam across the receiver aperture. The design, operation and transfer functions of the control system of the optical axes position are described.
