Title: COMMUNICATION DEVICE, COMMUNICATION METHOD, AND PROGRAM
Abstract:
The objective of the present invention is to continue communication even if a tracking error occurs and to reduce interference with respect to other transceivers when transmitting a video image/audio between an endstation facility and another endstation facility via a communication satellite transceiver. This transmission system (10) is provided with a tracking antenna (18) for tracking a transceiver (14), a tracking error calculation circuit (229) which obtains a tracking error in a tracking operation of the tracking antenna (18), a transmission level control circuit (232) which obtains a transmission level of a signal in accordance with the tracking error, and a transmitter (226) which transmits the signal at the obtained signal level through the tracking antenna (18) to the transceiver (14) of the communication destination.
