To provide "a pilotless aircraft and a pilotless aerial system" capable of achieving stable radio communication with a ground station.SOLUTION: A multi-copter 1 comprises four rotors 13 at each tip of four arms 12 extending in four directions at an interval of 90 degrees from a body 11. Each of antennas 101 is provided under each arm 12, for selective use for radio communication with a base station 2. The multi-copter 1 determines an antenna 101 closest to the base station 2 on the basis of a current position of the multi-copter 1 determined by a GNSS receiver 113, a current orientation of the multi-copter 1, and coordinates of the base station 2 preset in a memory 108, to be an antenna 101 that exists at a position which is not blocked by the multi-copter 1 itself with respect to the base station 2 at a current time point, and if the determined antenna 101 is not the antenna 101 that is currently being used for radio communication with the base station 2, sets the determined antenna 101 to an antenna 101 to be used for radio communication with the base station 2.SELECTED DRAWING: Figure 2

    【課題】地上局との間の安定した無線通信を実現する「無人航空機及び無人航空システム」を提供する。【解決手段】ボディ11から90度間隔で四方に伸びる4本のアーム12の先端に4つの回転翼13を備えたマルチコプタ1の各アーム12のそれぞれの下部に、基地局2との無線通信に選択的に用いるアンテナ101を設ける。マルチコプタ1は、GNSS受信機113で算出されるマルチコプタ1の現在位置と、マルチコプタ1の現在の向きと、メモリ108に予め設定されている基地局2の座標とから、基地局2に最も近いアンテナ101を、現時点において基地局2に対してマルチコプタ1自身によって遮られない位置にあるアンテナ101として算定し、算定したアンテナ101が、基地局2と無線通信に現在用いているアンテナ101と同じアンテナ101でなければ、算定したアンテナ101に基地局2と無線通信に用いるアンテナ101を切り替える。【選択図】図2
