1. A control device comprising:
a feeder link determination unit which determines a state of a feeder link established between one flight vehicle, which functions as a stratospheric platform, that forms a wireless communication area by emitting a beam, and wherein the one flight vehicle provides a wireless communication service to a user terminal in the wireless communication area and one gateway; and
a flight vehicle control unit which controls the one flight vehicle such that, when the feeder link determination unit determines that the state of the feeder link satisfies a predetermined switching condition, the one flight vehicle switches a data communication via the one gateway to a data communication via a communication device in the wireless communication area in which the one flight vehicle has established a service link,
wherein a beam having lower directivity in a low frequency band compared with a beam used for the feeder link is used for the service link.
