<p><P>PROBLEM TO BE SOLVED: To achieve a high capacity and high speed communication while suppressing frequency bandwidth. <P>SOLUTION: A data transmission system for a satellite communication is installed in a data relay satellite 2 and relays data transmission between a satellite 1 and terrestrial stations 20 to 22. The system receives data from the satellite 1 in an inter-satellite link antenna part 3. After dividing the data into a plurality of parallel data by a data division processing part 5, the system inputs the divided data one by one to a plurality of transmitter parts 70, 71, and 72 provided by associating with each of the terrestrial stations 20 to 22. Then, beam is formed by a beam forming circuit part 8 and is emitted to each of the terrestrial stations 20 to 22 from a multi-beam antenna part 9. The pieces of parallel data received at each of the terrestrial stations 20 to 22 are synthesized into single serial data at a terrestrial control station 12, and then restored to original data. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
