Operation system of unmanned aircraft

An operation system of an unmanned aircraft, comprising:

• a connecting cable comprising a connected part connected to the unmanned aircraft;
• a winder configured to wind a redundant part of the connecting cable to cause a tensile force to act on the connecting cable;
• a delivered amount detecting section configured to detect a delivered amount of the connecting cable delivered by the winder;
• a direction detecting sensor configured to detect a direction of a force acting on a to-be-detected part of the connecting cable between the connected part and the winder;
• a position determination section configured to determine a position of the unmanned aircraft;
• a takeoff and landing port where the unmanned aircraft takes off and lands, wherein:
• the unmanned aircraft is configured to fly in a passage space surrounded by a tubular wall extending in an up-down direction to transport an article;
• and
• the takeoff and landing port is disposed at a position connected to the passage space, wherein:
• the position determination section determines a distance from a predetermined reference position to the unmanned aircraft based on a detection result from the delivered amount detecting section;
• the position determination section determines an orientation of the unmanned aircraft on the basis of the to-be-detected part based on a detection result from the direction detecting sensor,
• the position determination section determines the position of the unmanned aircraft based on the distance from the predetermined reference position to the unmanned aircraft and the orientation of the unmanned aircraft on the basis of the to-be-detected part, and
• at least a part of the passage space where the unmanned aircraft is allowed to fly is below at least either of the winder and the direction detecting sensor.
