| Abstract(in English) | The Engineering Test Satellite 9 aims to verify the large capacity technology by Ka-band/optical communications and the technology to enhance the flexibility by digital payload to establish communications technologies for next generation High Throughput Satellite (HTS). This paper introduces the R&D activity of the flexible payload technology toward the Engineering Test Satellite 9 such as the multi-beam, digital channelizer, and digital beam former (DBF). Typical HTS employs Ka-band or higher frequency band to maintain wide bandwidth and employs hundreds of multiple beams to realize large capacity in order to reduce cost per bit. Technological challenge for the conventional HTS is that it does not properly accommodate changing traffic demand during operation since communications capacity for each beam is fixed. Flexible payload technology is expected to solve the technological challenge and efficiently utilize the communications resource. In the Engineering Test Satellite 9 project, technologies for multi-beam, digital channelizer for frequency flexibility and DBF for location flexibility are defined as the target technologies. Toward application to Ka-band HTS, the establishment of the miniaturization and integration of the multi-beam feeder unit, wide-band performance of digital channelizer and DBF are defined as the main development goals. To this end, the R&Ds and the development of payloads toward in-orbit verification by the Engineering Test Satellite 9 are in progress. |
