Abstract: The present invention aims to control position of flying object with respect to a structural object in a situation where it is difficult to perform positioning based on radio signals transmitted from a satellite. A position identification unit identifies position of flying object in troublesome GPS signal reception space, using different methods for coordinate axes. Specifically, position identification unit identifies position, on Z axis (first coordinate axis), of flying object in troublesome GPS signal reception space, based on distance from flying object to structural object (distance measured at time of position identification), and identifies positions, on X and Y axes (second coordinate axes), of flying object based on change in shape of structural object in respective axis directions of X and Y axes (second coordinate axes) (history of distance from flying object to bridge B measured multiple times until position identification).

Abstract: Time slot specifying unit reads out facility information of a facility to be inspected (specifically, a base station ID of a base station whose previous inspection day is included in a past predetermined period) from facility information storage unit. Daytime information acquiring unit acquires daytime information at positions at which base stations to be inspected are installed. Time slot specifying unit specifies non-backlight time slots based on the read-out facility information and the acquired daytime information. Operation plan generating unit generates an operation plan of drone in which facilities are shot in the specified non-backlight time slots. Operation plan outputting unit outputs the generated operation plan.

Abstract: A management system includes a storage unit that stores schedule information that indicates schedules of a plurality of tasks to be performed by the same flight vehicle. The schedule information includes types of the plurality of tasks, date/times of the plurality of tasks, and locations at which the plurality of tasks are to be performed. When the types, the date/times, and the locations that are included in the schedule information stored in the storage unit satisfy an integration condition, an integration unit integrates the schedules of the plurality of tasks. An output unit outputs integrated schedule information indicating the schedules of the integrated tasks.

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.

Abstract: Server apparatus, by controlling aerial vehicle, causes aerial vehicle to fly within a close range of an animal group, and causes aerial vehicle to capture images of the animal group. Aerial vehicle transmits captured image data to server apparatus via communication network, and server apparatus checks a health state of animals of the animal group using the captured image data with a method such as image analysis. Server apparatus performs machine learning using position information history of wireless terminals attached to animals (that is, a movement history of the animal group), specifies an area for checking the state of the animal group, and causes aerial vehicle to fly to the specified area and to capture images of the animal group.

Abstract: A flight information acquisition unit repeatedly acquires the respective flight status of a plurality of drones in flight. A flight irregularity determination unit determines whether or not the drones are flying in a manner deviated from a flight plan. When a flight status of a drone indicating flight deviated from the flight plan has been acquired, a first collision specification unit specifies the drone at risk of collision with a drone having that flight status. When a flight status indicating that there is a possibility of crash for a drone has been acquired, a flight status processing unit (such as a flight irregularity determination unit) sets a higher priority for processing based on the flight status acquired from that drone than for processing based on the flight status acquired from another drone.

Abstract: If a propagation delay equal to or greater than a threshold value is detected in the uplink of a time-division duplex between a first wireless communication terminal and a first wireless base station, a suppression unit 52 performs control pertaining to resources in the time-division duplex of a first wireless communication terminal. Thereby, communication errors that occur in a second wireless communication terminal wirelessly connected to the second wireless base station that is different from the first wireless base station, to which the first wireless communication terminal is wirelessly connected, is suppressed by uplink communication performed by the first wireless communication terminal in accordance with the propagation delay. For example, this suppression process is a process pertaining to the assignment of resources a time-division duplex with respect to the first wireless communication terminal.

Abstract: A flight control apparatus includes a detection unit that detects within a predetermined range of an air vehicle another air vehicle. A specifying unit specifies a type of the detected other air vehicle. A determining unit determines a possibility that the air vehicle and the other air vehicle will collide, based on an attribute relating to movement of the other air vehicle. When it is determined that a possibility of collision exists, a flight control unit controls the flight of the air vehicle according to the specified type of the other air vehicle to avoid collision with the other air vehicle.
