A control system and method for tensioning an active tether for a multirotor unmanned aerial system is provided. The control system includes a tensioning pulley and a tensioning spring. The tensioning spring is arranged to generate a variable tension force on the active tether. A transducer is connected adjacent to the tensioning spring to sense a linear displacement position of the tensioning pulley and to transmit a position signal to a controller. The position signal is proportional to the linear displacement position. A servomotor in communication with the controller receives a control signal from the controller in response to the position signal. The servomotor drives a cable reel. The cable reel is rotatably mounted in the frame for spooling the tether in response to rotation of the servomotor. The cable reel is rotated by the servomotor to maintain a predetermined tension on the tensioning spring.

The method for producing bindings includes: positioning at least one binding bobbin on a machine having: a winding bobbin including a device for supporting and a notch, an electric motor which is coupled to the winding bobbin; and at least one shaft capable of receiving a binding bobbin, supporting a free end of the binding of the binding bobbin on the winding bobbin, by the device for supporting; supplying electricity to the electric motor of the machine to drive the winding bobbin in rotation, so as to wind the binding of the binding bobbin over a plurality of turns around the winding bobbin; stopping the supply of electricity to the electric motor of the machine; and in the region of the notch of the winding bobbin, cutting the plurality of turns of bindings wound onto the winding bobbin.
