The paper aims to analyse the challenges European supply chains face in the context of satellite communications (specifically, in the Copernicus programme) amidst geopolitical and pandemic disruptions. It focuses on identifying factors and barriers and recommended solutions to enhance resilience in these supply chains. The study employs a comprehensive approach, incorporating Delphi surveys, a literature review, and the STEEPED analysis. Experts from the satellite communications field participated in the Delphi survey, and the study scrutinised the impact of Delphi theses on various stages of supply chains. STEEPED analysis was used to identify factors enhancing the resilience of European supply chains in satellite communications. An analysis of their validity and uncertainty was also carried out. The research highlights the factors influencing supply chain resilience within satellite communications, emphasising the importance of coping with uncertainty, shocks, and disruptions. The study presents valuable recommendations to strengthen supply chain resilience amid infrastructural and geopolitical challenges. This research enriches insights into building resilience strategies for European supply chains operating within intricate and uncertain environments. By analysing the role of the Copernicus programme and Earth observation data, the paper contributes to the theoretical framework, providing essential knowledge for managing supply chains in a dynamic and complex environment. The study’s recommendations offer practical guidance for EU institutions overseeing the Copernicus programme and its users. By effectively leveraging Copernicus and Earth observation data, stakeholders can enhance their analysis methods. These insights enable practical actions to be taken, ensuring the continuity and stability of European supply chains amidst challenging global scenarios.
