Japan Completes System Definition Review for Commercial Payload Supply Ship Development
Japan LEO Shachu, Inc. Completes System Definition Review (SDR) for HTV-XC Project
Japan LEO Shachu, Inc., headquartered in Chuo-ku, Tokyo, has successfully concluded the System Definition Review (SDR) for its ongoing development project of the Japanese Module and the Commercial Payload Supply Ship (HTV-XC). This development is part of a larger initiative backed by the Space Strategy Fund, focusing on advancing technologies associated with autonomous flight module systems and enhancing international competitiveness and self-sufficiency in payload supply systems.
The SDR is a crucial milestone in ensuring that the design approaches, key specifications, system architecture, interface definitions, and verification strategies align with mission requirements. The successful completion of this review confirms the feasibility of the system architecture and requirement allocation for both the Japanese Module and the HTV-XC, allowing the project to transition into the next phase: Preliminary Design.
This development project is strategic in constructing a sustainable economic zone in low Earth orbit (LEO), which is anticipated to flourish in the post-International Space Station (ISS) era. It aims to bolster Japan’s competitiveness in the aerospace industry while paving the way for new commercial space markets.
Moving forward, the focus will shift toward deepening the preliminary design of each subsystem. This includes advancing the design work to finalize key interfaces and the distribution of functions and performance.
The company remains committed to pushing forward the establishment of Japan's space infrastructure through a public-private partnership framework, leveraging the robust backing of the Space Strategy Fund.
