U-Space and Tenchijin Announce Strategic Partnership to Deploy Next-Generation Infrared Earth Observation System
U-Space, a French NewSpace company, and Tenchijin, a Japanese space technology company, have signed a Memorandum of Understanding (MoU) to collaborate on the deployment of a next-generation infrared Earth observation space system. The agreement marks an important step toward developing a commercial satellite infrastructure capable of delivering high-resolution and high-frequency thermal data for applications across agriculture, infrastructure, water management, and climate resilience.
The MoU was signed during the bilateral sequence of the International Space Summit in Paris, bringing together representatives from the French and Japanese space ecosystems. The agreement establishes a commercial and technological partnership between the two companies and highlights the growing role of international cooperation in the development of privately driven space infrastructure.
The collaboration also builds on the longstanding relationship between France and Japan in the space sector. In particular, the agreement follows bilateral agreements signed in April between the French Space Agency (CNES) and the Japan Aerospace Exploration Agency (JAXA). Those agreements established a framework for continued cooperation between the two countries, while the new U-Space and Tenchijin partnership represents a more commercially focused and operational development of that broader relationship.
Combining French Space Engineering With Japanese Data Expertise
Under the partnership, U-Space and Tenchijin will contribute complementary capabilities to the development and commercialization of the infrared Earth observation system.
U-Space will serve as the industrial prime contractor for the project. Its responsibilities will cover the end-to-end design, manufacturing, and delivery of the next-generation space system, as well as the development of the future satellite constellation. This role positions U-Space at the center of the infrastructure required to collect and deliver thermal Earth observation data at scale.
Tenchijin, meanwhile, will be responsible for operating and using the system while developing commercial opportunities around the resulting data. The Japanese company plans to transform high-resolution, high-frequency thermal information into services designed to address practical challenges faced by businesses, governments, and other organizations.
By combining U-Space’s capabilities in satellite system development with Tenchijin’s experience in turning Earth observation data into commercially useful insights, the partnership aims to create an integrated value chain extending from spacecraft development to real-world applications.
Growing Importance of Thermal Earth Observation
The planned constellation will focus on infrared observations and the generation of land surface temperature (LST) data. LST information provides an important measure of how Earth’s surface absorbs and emits heat, making it valuable for monitoring environmental conditions and identifying changes that may not be visible through conventional imagery alone.
As climate pressures intensify and infrastructure systems age, demand for more detailed and frequently updated thermal information is increasing. High-resolution LST data can help organizations understand changes in surface conditions, identify areas experiencing abnormal heat, monitor environmental stress, and make more informed decisions.
Water resource management represents one particularly important application. Thermal observations can contribute to the detection and monitoring of water-related issues, including conditions associated with inefficient water use and infrastructure challenges. Access to frequent thermal information could help cities, utilities, and other organizations develop more proactive approaches to managing increasingly valuable water resources.
Agriculture is another major application area. Temperature information collected across agricultural landscapes can provide insights into crop and soil conditions, water stress, irrigation requirements, and broader environmental changes. When combined with other forms of Earth observation and analytical technologies, thermal data can support more precise agricultural decision-making and help farmers and agricultural organizations improve resource efficiency.
The technology could also contribute to infrastructure monitoring. Urban areas and critical infrastructure are exposed to increasing environmental pressures, while many systems are reaching the later stages of their operational lives. More frequent thermal observations could help identify changes and anomalies that warrant further investigation, supporting preventive maintenance and improved infrastructure management.
Supporting Climate Risk Mitigation
Climate adaptation is expected to be another significant area of application for the planned system. Governments, companies, and communities increasingly need reliable data to understand and manage risks associated with changing temperatures, water availability, extreme weather, and other environmental pressures.
Traditional observation methods can provide valuable information, but satellite-based thermal monitoring offers the potential to deliver consistent coverage over large geographic areas. A dedicated infrared constellation designed around high-frequency observations could therefore provide an additional layer of information for organizations developing climate adaptation strategies.
For Tenchijin, the partnership builds directly on its experience applying satellite data to practical problems. The company has previously worked on using Earth observation technologies to identify invisible water leaks beneath cities in Japan. The new collaboration represents an evolution of that approach, moving from using existing satellite data toward developing dedicated infrastructure tailored to the information requirements of its customers.
Yasuhito Sakuraba, CEO of Tenchijin, emphasized that the company’s objective is to focus on the value created by space-based data once it reaches users on Earth. According to Sakuraba, the new infrared constellation is intended to be designed from the outset around customer data requirements, enabling thermal insights to be applied to challenges including aging water infrastructure, food security, and climate adaptation.
Strengthening the French-Japanese NewSpace Connection
The agreement also illustrates the increasing international reach of the French and Japanese NewSpace ecosystems. Rather than limiting commercial space development to domestic or regional markets, companies in both countries are increasingly seeking partnerships that combine specialized capabilities and address global demand.
For U-Space, the agreement represents an opportunity to demonstrate its ability to operate as a prime industrial contractor for an international satellite constellation. Thomas Pfister, CEO of U-Space, described the partnership as a major milestone for the company and said it demonstrates the capacity of the French NewSpace ecosystem to build partnerships beyond Europe.
Pfister also highlighted the environmental and infrastructure challenges that the planned system is intended to address. By working with Tenchijin, U-Space aims to develop space infrastructure that can translate advanced satellite engineering into practical solutions for issues affecting societies and economies around the world.
From Space Technology to Commercial Applications
One of the defining characteristics of the partnership is its focus on the commercial value of Earth observation data. Rather than treating satellite deployment as an end in itself, the two companies are building the project around downstream applications and customer needs.
This approach reflects a broader transformation taking place across the global space industry. Advances in satellite manufacturing, launch services, sensors, data processing, and analytics are making it increasingly possible for commercial organizations to develop specialized Earth observation systems. At the same time, demand is growing for data that can support decisions in sectors such as agriculture, utilities, insurance, infrastructure, and environmental management.
The proposed infrared constellation could become part of this evolving commercial Earth observation landscape by providing thermal information at a level of frequency and resolution designed for operational use.
For agriculture and food systems in particular, improved thermal monitoring could support more efficient water use and help stakeholders respond to changing environmental conditions. Such capabilities could become increasingly important as producers face pressure to increase productivity while managing limited resources and adapting to climate variability.
