Abstract: A technique for more reliably capturing a lost unmanned aerial vehicle in tracking the unmanned aerial vehicle by a surveying device is provided. A UAV search area setting part is configured to perform arithmetic operation for searching for an unmanned aerial vehicle having mounted therein a location identifying device using a GNSS. The UAV search area setting part includes a measured location obtaining part that obtains information of a location of the unmanned aerial vehicle, which is measured by a surveying device, a scheduled flight location obtaining part that obtains information of a scheduled flight location of the unmanned aerial vehicle from a flight plan of the unmanned aerial vehicle, and a search area setting part that sets an area for searching for the unmanned aerial vehicle by referring to a difference between the measured location and the scheduled flight location at a specific time.
