Abstract
A station-side telescope included in a station-side optical antenna unit is configured to transmit and receive an optical signal, a guide light source is configured to emit guide light in a direction of orientation of the station-side telescope, a node-side telescope is configured to transmit and receive an optical signal, a node-side control unit included in a node-side optical antenna unit is configured to generate and output a control signal for moving a node-side base based on a position of the guide light included in an image obtained by a camera capturing the guide light emitted by the guide light source so that a direction of orientation of the node-side telescope faces the direction of orientation of the station-side telescope, an antenna drive unit is configured to receive the control signal and generate and output a drive signal based on the control signal, and the node-side base included in the node-side optical antenna unit is configured to support the node-side telescope and receive the drive signal to change a direction of orientation of the node-side telescope.
