Abstract

An artificial satellite includes a recording device, a calculator, and a communication device. The communication device includes a beam control device and a beamforming device. The recording device has recorded therein information indicating communication traffic between the communication device and at least any of a plurality of gateways disposed on ground. When imbalances in communication traffic among the plurality of gateways are present, the calculator derives variable parameters for controlling the beamforming device so that the imbalances in the communication traffic among the plurality of gateways decrease, and transmits the derived variable parameters to the beam control device. The beam control device receives the variable parameters derived by the calculator and controls the beamforming device based on the received variable parameters.
