PROBLEM TO BE SOLVED: To provide an unmanned aircraft direction and position detection system that strongly prevents a crash, or recovery by a third person thanks to more correct grasping of an own position by an unmanned aircraft itself.SOLUTION: An unmanned aircraft direction detection system detects a direction at a current time of an unmanned aircraft 3 flying from a departure point to an arrival point, and has: a ground transmission source that encrypts an optical signal inclusive of at least position information on an own, and transmits the encrypted optical signal; an encryption decryption unit 58 that receives the optical signals transmitted from two or more ground transmission sources to decrypt the received optical signal, and thereby acquires the position information on the ground transmission source; a signal incident direction detection unit 59 that identifies an incident direction of the optical signal; and a control unit 57 that calculates a current direction with respect to the ground transmission source on the basis of the position information acquired by the encryption decryption unit 58, and the incident direction identified by the signal incident direction detection unit 59.SELECTED DRAWING: Figure 2

    【課題】無人航空機自体が自らの位置をより正確に把握することで、墜落や第三者による回収を強固に防止する無人航空機の方向、位置検知システムを提供する。【解決手段】出発地点から到着地点まで飛行する無人航空機3の現時点の方向を検知するための無人航空機の方向検知システムにおいて、少なくとも自らの位置情報を含めた光信号を暗号化した上で発信する地上発信源と、2つ以上の地上発信源から発信された光信号を受信してこれを復号することにより地上発信源の位置情報を取得する暗号復号部58と、光信号の入射方向を識別する信号入射方向検知部59と、暗号複合化部58により取得した位置情報及び信号入射方向検知部59により識別された入射方向に基づき地上発信源に対する現在の方向を算出する制御部57とを有する。【選択図】図2
