PROBLEM TO BE SOLVED: To avoid deterioration of communication quality even if shielding occurs or a communication range is long, by a data collector 1 moving on the ground or in the air.SOLUTION: A method comprises the steps of: acquiring positional information of a data collector 1, positional information of a repeater 3, information related to a communication state between the data collector 1 and the repeater 3, and information related to a communication state between the repeater 3 and a ground device 2; and, on the basis of these pieces of information, determining a vista state between the data collector 1 and the repeater 3 and controlling a position of the repeater 3 to secure a vista between the data collector 1 and the repeater 3.SELECTED DRAWING: Figure 7
【課題】データ収集機1が地上または空中を移動することで、遮蔽が発生したり通信距離が長くなったりした場合でも、通信品質の劣化を回避できるようにする。【解決手段】データ収集機1の位置情報、中継機3の位置情報、データ収集機1と中継機3との間の通信状況に関する情報、および中継機3と地上機2との間の通信状況に関する情報を取得して、これらの情報に基づいて、データ収集機1と中継機3との間の見通し状態を判定して、データ収集機1と中継機3との間の見通しが確保されるように、中継機3の位置を制御する。【選択図】図7
