Control device, program, system, and control method

A non-transient computer-readable medium storing instructions that, when executed by a computer, causes the computer to function as:

• a flight vehicle position information acquisition unit which acquires service flight vehicle position information indicating positions of a plurality of service flight vehicles, each of which functions as a stratosphere platform and is mounted with a communication device which forms a wireless communication area by emitting a beam and provides a wireless communication service to a user terminal in the wireless communication area;
• an arrangement determination unit which determines arrangement of a relay flight vehicle which relays communication of one service flight vehicle among the plurality of service flight vehicles on a basis of a predetermined condition and the service flight vehicle position information;
• a flight vehicle control unit which controls the relay flight vehicle to move according to the arrangement determined by the arrangement determination unit and establish wireless communication connection with the one service flight vehicle;
• and
• a weather-related information reception unit which receives weather-related information on weather in the wireless communication area formed by each of the plurality of service flight vehicles, the weather-related information including rainfall information indicating a rainfall in the wireless communication area formed by each of the plurality of service flight vehicles.

A control method which is executed by a computer, the control method comprising:

• acquiring flight vehicle position information by acquiring service flight vehicle position information indicating positions of a plurality of service flight vehicles, each of which functions as a stratosphere platform and is mounted with a communication device which forms a wireless communication area by emitting a beam and provides a wireless communication service to a user terminal in the wireless communication area;
• determining arrangement of a relay flight vehicle which relays communication of one service flight vehicle among the plurality of service flight vehicles on a basis of a predetermined condition and the service flight vehicle position information;
• controlling a flight vehicle by controlling the relay flight vehicle to move according to the arrangement determined by the determining arrangement and establish wireless communication connection with the one service flight vehicle;
• and
• receiving weather-related information on weather in the wireless communication area formed by each of the plurality of service flight vehicles, the weather-related information including rainfall information indicating a rainfall in the wireless communication area formed by each of the plurality of service flight vehicles.
