Abstract: The flight control part 201 makes the unmanned aerial vehicle fly along a flight path in a predetermined area. The radio wave acquisition part 202 acquires radio wave information including a radio wave intensity when the radio unit of the unmanned aerial vehicle detects a short-distance radio wave of the user terminal during the flight of the unmanned aerial vehicle. The flight position acquisition part 203 acquires GPS position information of the unmanned aerial vehicle when the radio unit detected the short-distance radio wave, as a flight position of the unmanned aerial vehicle based on a GPS unit of the unmanned aerial vehicle. The terminal position calculation part 204 calculates a presence position of the user terminal in the area based on a radio wave intensity of the acquired radio wave information, and the acquired flight position of the unmanned aerial vehicle.

Abstract: The transmission part transmits communication information including the terminal ID of the user terminal, the unit ID of the wireless unit and radio wave intensity to a server, when the user terminal performs short-distance wireless communication to the wireless unit through the radio wave. The collection part collects a chronological change of the radio wave intensity in the terminal ID concerned with the unit ID. The calculation part calculates the flow line that the user moved in the area of the wireless unit and the flow time when the user stays on a part of the flow line. The estimation part estimates action information indicating that the user did actually on the area of the wireless unit. The analysis part analyzes the user's attribute information including the user's preference based on the user's action information and the installation attribute information.
