The Value of Our Research
- We aim to contribute to the construction of the society5.0 platform promoted by the Japanese government, and achieve an internationally competitive, high-speed communication satellite system required for the 2020s. (We aim to technologically verify the Engineering Test Satellite-9 project currently under development, and, following on the next-generation geostationary communications satellite which is an internationally competitive satellite system, to research the technology required for future generations of geostationary indications satellites.)
- In addition to the requirements on the ground, we aim to construct a high-speed communication satellite system that can contribute to missions in fields such as earth observation, space science/planetary exploration, and space environment use.
Research Goals
In terms of the keywords in satellite communication system international competitiveness, we have broadly categorized our research into the following three sub-themes.
Optical communications technology research
- Research into high-speed, lightweight optical communications devices
- Research into high-power optical amplifiers
- Research in optical ground stations (optical communications, debris observation) and operation of optical ground stations
RF satellite communications technology research
- Research into high-speed transmission systems
- Research related to communications payload
Low-cost, lightweight, high-performance bus device research
- Research on active thermal control technology (two-phase mechanically pumped loop)
- Research into solar batteries for space use
- Research into more compact and lightweight power control devices
- Research into lightweight/low-cost batteries
