通信装置。 It consists of a transmitting/receiving antenna that has a region where the transmitting/receiving gain pattern decreases in some parts, a received signal level detector, and a transmitter that has two modes, low output and high output. The artificial intelligence is characterized in that the received signal level decreases when a ground station links to an area with low Satellite communication equipment.
