2025 Agenda

The EURIALO project, supported by the European Space Agency (ESA), is advancing a new space-based surveillance layer designed to strengthen the resilience and continuity of Air Traffic Management (ATM). Building on its introduction at previous editions of Airspace World, this presentation focuses on EURIALO’s progress toward operational maturity and its role in complementing existing terrestrial surveillance infrastructures.
By leveraging a micro-satellite constellation and advanced multilateration (MLAT) techniques, EURIALO enhances global surveillance coverage, including in remote or interference-prone environments. Fully aligned with SESAR priorities and the European ATM Master Plan, and covered by CNS evolution MP, the project delivers tangible benefits in safety, operational performance, and sustainability. Developed by a consortium including Spire, Thales, ESSP, and ENAV, EURIALO is currently in its In-Orbit Demonstration phase, marking a key milestone on the path to operational space-based surveillance services.
