  • Patent number: 12154438
    Abstract: The present invention suppresses the case where communication performed by a radio communication apparatus of one flight vehicle is negatively influenced in the case where the radio communication apparatus of the one flight vehicle is connected to a radio base station that is experiencing interference due to a radio communication apparatus of another flight vehicle. A distance specification unit specifies, for each airspace, a distance between a first flight vehicle and a second flight vehicle that has a radio communication apparatus and is located in a cell formed by a radio base station that is experiencing interference due to a radio communication apparatus of the first flight vehicle. An instruction unit instructs, in each airspace, the first flight vehicle and the second flight vehicle to maintain the distance specified for the airspace by the distance specification unit when flying.
