The University of Portsmouth has launched a new international partnership with Saudi space technology company SARsatX to design a climate-focused Earth observation satellite mission concept. The collaboration is supported by the Saudi Space Agency and backed by funding from the UK Government’s Gulf Strategy Fund.

The initiative brings together researchers and engineers from both countries to define a satellite mission aimed at strengthening climate monitoring and environmental resilience. The project is being delivered within the Space South Central regional space cluster, with academic contributions from the University of Surrey and University College London alongside UK industry partners.

Strategic Focus on Climate and Environmental Data

The proposed mission concept is intended to support sectors reliant on accurate environmental intelligence, including agriculture, infrastructure planning and climate risk management. By aligning scientific expertise with technical system design, the partners aim to develop a satellite architecture capable of generating high-quality data for climate analysis and resilience planning.

The collaboration also aligns with Saudi Arabia’s efforts to expand domestic satellite capabilities and build its national space ecosystem. For the United Kingdom, the partnership reflects a broader strategy to strengthen international space cooperation and position UK institutions within emerging global space markets.

Concurrent Design Approach

The mission concept is being developed using a concurrent design methodology, allowing multidisciplinary teams to iterate system components in parallel. UK and Saudi specialists are jointly assessing payload configurations, orbital parameters and downstream applications to ensure the mission reflects shared scientific and operational priorities.

Over the coming months, the teams will conduct virtual workshops and reciprocal visits to refine technical specifications and explore application use cases. These engagements are designed to ensure the mission concept remains aligned with user requirements in climate science and environmental services.

Building a Long-Term Roadmap

The project will conclude with a strategic roadmap outlining pathways for continued cooperation. This roadmap is expected to identify future joint missions, research collaborations, training programmes and knowledge exchange mechanisms.

Officials involved in the initiative emphasised that Earth observation systems play an increasingly central role in climate monitoring, disaster preparedness and resource management. As governments and private operators expand satellite constellations, international partnerships are becoming a core mechanism for sharing expertise, managing costs and accelerating technological development.

By focusing on mission design rather than immediate deployment, the UK–Saudi collaboration seeks to establish the technical and institutional foundation for future climate-oriented satellite programmes, while reinforcing bilateral ties within the rapidly evolving global space economy.
