Research for Secure Development and Success of Missions
Research on core technologies for spacecraft (electrical power subsystems)

Among the technologies critical to spacecraft (satellites and other vehicles operated in space), our research focuses on core technologies required to operate spacecraft power subsystem more reliably. We have been striving to overcome challenging new obstacles to meet the requirements for future space missions while ensuring the secure, reliable implementation of our ongoing projects.

To improve the performance of spacecraft subsystems, we have researched ways to improve the technologies for spacecraft guidance navigation control, data transmission, and solar cells. We have also conducted the Space Environment Data Acquisition Mission to obtain the basic space environment data required for spacecraft development. We continue to use this basic data to research environmental effects on spacecraft in space, such as material degradation.
