IHI Corporation and UK-based Global Satellite Vu Ltd (SatVu) signed a memorandum of understanding at DSEI 2025 to jointly develop a thermal‑infrared satellite constellation. The collaboration aims to bolster Japan’s sovereign Earth‑observation capability for defence intelligence and climate and environmental monitoring.

Briefing
The MoU directly advances Japan’s sovereign EO capacity by pairing a domestic systems integrator with SatVu, a company already contracted to deliver thermal imagery for next‑generation defence programs (see SatVu’s work with the NGA). (https://hype.aero/?story=f4ada4e7-f1b4-41f9-93f1-5915c4401b3e)
This aligns with a broader push by governments to secure national space‑based ISR and environmental monitoring assets, similar to other recent sovereign procurement deals in Europe and Japan’s own space investment activity. (https://hype.aero/?story=464b0db7-d9a9-45bd-abdb-596378b6144c)
Thermal‑IR constellations deliver mission‑critical capabilities—wildfire, infrastructure heat signatures and nocturnal surveillance—demonstrated by recent operational thermal missions and imagery returns. (https://hype.aero/?story=076d2485-6f74-46e5-b05c-d9a93a12faa5)
