To provide an unmanned flight body, an unmanned flight method, and an unmanned flight program with which positions flown by a drone are kept unknown to a third party.SOLUTION: An unmanned flight body 1 capable of an autonomous flight comprises: positioning means for measuring a current position and calculating a measured position, by using positioning radio waves from a navigation satellite; estimation means for estimating a current position and calculating an estimated position, on the basis of movement of the unmanned flight body 1 and a predetermined reference position; reliability calculating means for calculating a degree of reliability of the positioning according to the positioning means; position determining means for determining the measured position or the estimated position as the current position, on the basis of the degree of reliability; encryption means for encrypting the current position determined by the position determining means; and position transmitting means for transmitting the current position encrypted by the encryption means to a receiving device capable of decrypting the current position encrypted by the encryption means.SELECTED DRAWING: Figure 5

    【課題】ドローンが飛行した位置を第三者に知られることがない無人飛行体、無人飛行方法及び無人飛行プログラムを提供すること。【解決手段】自律飛行可能な無人飛行体1は、航法衛星からの測位用電波を使用して、現在位置を測位して測位位置を算出する測位手段と、無人飛行体1の動きと所定の基準位置に基づいて、現在位置を推定して推定位置を算出する推定手段と、測位手段による測位の信頼度を算出する信頼度算出手段と、信頼度に基づいて、測位位置または推定位置を前記現在位置として決定する位置決定手段と、位置決定手段によって決定した現在位置を暗号化する暗号化手段と、暗号化手段によって暗号化された現在位置を復号することができる受信装置に対して、暗号化手段によって暗号化した現在位置を送信する位置送信手段と、を有する。【選択図】図5
