ARTES Weekly Series - Eurialo: Global, Real-Time Aircraft Tracking from Space • Nov 2025
The European Space Agency’s Advanced Research in
Telecommunications Systems (ARTES) programme helps turn innovative concepts
into commercial reality. Under ARTES Space Systems for Safety & Security
(4S), Eurialo
is developing a satellite-based system for real-time, global aircraft tracking.
The project presents a breakthrough that
will transform the safety, security, and sustainability of air travel.
Eurialo overcomes the limitations of traditional
radar, providing uninterrupted coverage even over oceans and remote regions.
This capability will enable more efficient air traffic management and support
the eventual decommissioning of terrestrial tracking stations. Aligned with the
European Air Traffic Management (ATM)
Master Plan, Eurialo ensures resilient, space-based infrastructure for global
aviation, offering both operational and environmental benefits.
ESA’s role has been central, providing €10.6
million in funding to a European consortium bringing together the German,
French, and Italian space agencies alongside multiple industry partners. ESA
experts worked closely with the team to validate technical assumptions, refine
designs, and accelerate progress through a highly collaborative, results-driven
approach. This support has helped de-risk the project while laying the
groundwork for scaling to a full constellation.
The results already
point to a significant step forward:
·
In-orbit demonstration
scheduled for 2026
·
Expected to reach
around 180 customers worldwide
·
Saving
contributions of €525 million expected by
2040 through allowing for the decommissioning of
terrestrial stations
·
Cost-saving advantages
for developing countries and improved resilience for navigation providers
·
Enabled
expansion of industry partner
with a new office in Munich to support growth
As the project team from Spire
notes, “Space-based aircraft tracking and geolocation is the future of air
traffic management to ensure safe, secure and sustainable air travel at a
global scale.”. With the in-orbit
demonstration approaching and commercial uptake expected to grow rapidly,
Eurialo is poised to become a cornerstone of next-generation aviation safety.

see how ESA is enabling innovation, competitiveness, and socio-economic
benefits across Europe’s space sector.
