DRONE SYSTEM, FLIGHT MANAGEMENT DEVICE, AND DRONE

摘要

The purpose of the present invention is to prevent a sprayed chemical from escaping from an agricultural field when spraying the chemical in the agricultural field. A drone system 1000 comprises: a flight control unit 1001 that flies a drone 100 along a flight route in the air over an agricultural field 403; a spray control unit 1002 that sprays a chemical M on the agricultural field; and a flight management unit 600 that determines the flight altitude of the drone at locations along the flight route, wherein the flight route includes an edge section route 413a along which the drone flies while spraying the chemical on an edge section 403a of the agricultural field, and a center section route 413b along which the drone flies while spraying the chemical on a center section 403b that to the inside of the edge section, and the flight management unit performs control such that the flight altitude of the edge section route is lower than the flight altitude of the center section route.
