Title: CONTROL STATION, SATELLITE STATION, EARTH STATION, DATA TRANSMISSION SYSTEM, AND DATA TRANSMISSION METHOD
Abstract:
A control station comprises: a position management unit (402) for calculating, on the basis of the position of a satellite station that transmits data to an earth station and the positions of earth stations that are candidates to which data is to be transmitted from the satellite station, a possible communication time for a combination of the satellite station and the earth station that can communicate with each other; a data management unit (403) for holding information on the state of retention of data in the satellite that has generated the data; and a transmission prediction unit (404) for calculating a data transmission completion time for one or more transmission paths from the satellite station that has generated the data to the earth station, on the basis of the possible communication time and the information on the state of retention of the data, and generating, for the satellite station and the earth station using a transmission path determined on the basis of the data transmission completion time, control information for transmitting the data through the determined transmission path.
