To provide a technique for enabling an autonomous flight of an unmanned aircraft.SOLUTION: An unmanned aircraft 1 performs the steps of: allowing the own aircraft to take off at a position where a position marker arranged in the vicinity of a flight route can be photographed; and obtaining a reference position of the own aircraft based on position information of the photographed position marker, calculating the present flight position of the own aircraft by estimation by estimating a position deviation from the reference position during the flight on the flight route, and transmitting the position information of the present flight position calculated by estimation in place of the position information of a signal from a position measurement system when accuracy of the position information included in the signal is lower than a threshold.SELECTED DRAWING: Figure 11

    【課題】無人航空機の自律飛行を可能とする技術を提供する。【解決手段】無人航空機1は、飛行ルートの傍らに配置された位置マーカを撮影可能な位置で自機を離陸させるステップと、撮影した位置マーカの位置情報を基に自機の基準位置を求め、上記飛行ルートの飛行中に上記基準位置からの位置ズレを推定することにより自機の現在の飛行位置を推定計算し、位置測定システムからの信号に含まれる位置情報の精度が閾値よりも低い場合、その信号の位置情報の代わりに上記推定計算した現在の飛行位置の位置情報をフライトコントローラへ送信するステップと、を行う。【選択図】図11
