R&D on critical space equipment and parts

It is imperative to maintain self-determination and flexibility in Japan's space programs. Accordingly, we select and develop critical space components to ensure the continuous supply and the quality of components. In order to increase availability of space components, we also assess applicability of the development. In using the commercial components timely and approproately, we can establish the components supply system that enables us to produce a small lot of components at an optimal cost. We also promote to integrate components technology information so that involes parties may access the databeses and conduct relevant projects more efficiently.

Orbital demonstration

It is essential to demonstrate and verify newly developed devices in the space environment. They are important to achieve higher performance and reliability in satellites. Moreover, with these equipment and parts, IAT is developing a series of micro satellites.
Micro-Labsat was launched by H-IIA Launch Vehicle No.4 in 2002 and successfully conducted all experiments.
Small Demonstration Satellite-1 (SDS-1) was a 100 kg-class tiny satellite launched by the H-IIA Launch Vehicle No. 15 in January, 2009. The SDS-1’s operation was completed on September 8, 2010, after achieving all its missions. Knowledge learned throughout the SDS-1’s life cycle from its development to operation will be incorporated into the fourth SDS (SDS-4) to further study more efficient development methods for satellites.
