To provide a descending system that can land an unmanned flight body at an accurate target position.SOLUTION: Target markers are comprised of layer markers at several stages that have different outer shape sizes in a horizontal direction. A layer marker with a relatively small outer shape is arranged on an inner side of a layer marker with a relatively large outer shape. When the layer marker with the relatively large outer shape is recognizable within a photographic range of image acquiring means, an unmanned flight body descends while performing control so that the layer marker with the relatively large outer shape is positioned within the photographic range. If the layer marker with the relatively large outer shape becomes unrecognizable within the photographic range as a result of lowering the unmanned flight body, the unmanned flight body descends while performing control so that the layer marker with the relatively small outer shape is positioned within the photographic range.SELECTED DRAWING: Figure 13

    【課題】正確な目標位置に着陸することができる降下システムを提供すること。【解決手段】目標標識は、水平方向における外形の大きさが異なる複数段階の階層標識から構成され、相対的に外形が小さな階層標識は、相対的に外形が大きな階層標識の内側に配置され、無人飛行体は、画像取得手段の撮影範囲内において相対的に外形が大きな階層標識を認識可能な場合には、相対的に外形が大きな階層標識が撮影範囲内に位置するように制御しつつ降下し、無人飛行体が降下した結果、撮影範囲内において相対的に外形が大きな前記階層標識が認識不可能になった場合には、相対的に外形が小さな階層標識が撮影範囲内に位置するように制御しつつ降下する。【選択図】図13
