Russia’s war of aggression against Ukraine is demonstrating the new role of commercial space systems in crisis management. The improved availability of commercial satellite data and signals is contributing to the quality and resilience of government systems, with telecommunications and follow-ups of military actions and impacts on the ground for civilians. But the war has also revealed vulnerabilities of space infrastructure and in global supply chains. It also unleashed a series of new threats, notably unanticipated third-party uses of satellite data and disruptions of civilian telecommunications. Furthermore, the current geopolitical situation raises questions about the future of international co-operation in space activities, at a time when it is urgently needed to collectively manage the use of orbital resources. This policy note includes OECD recommendations for policy responses to improve the resilience of space infrastructure, manage access to and use of data and signals and ensure long-term sustainability of space activities.
