Thales has officially lifted the veil on AURORE, a revolutionary ground-based radar system poised to become Europe’s largest and most sophisticated sensor for tracking objects in Low Earth Orbit (LEO). Developed under the French Defence Procurement Agency’s (DGA) ARES program (Action and Space Resilience), this major technological achievement marks a decisive step toward bolstering European space sovereignty and strategic autonomy.
In a rapidly escalating « New Space » era, where mega-constellations and military assets proliferate, the ability to maintain independent Space Situational Awareness (SSA) is no longer negotiable. AURORE provides France and its European partners with the critical tools needed to monitor, track, and protect valuable assets hundreds of kilometres above Earth.
The Technology: A Software-Defined LEO Guardian
AURORE is not merely an incremental upgrade; it represents a technological leap forward in radar design.
- UHF Operation: Operating in the Ultra High Frequency (UHF) band, AURORE offers robust detection capabilities.
- Software-Defined Architecture: Built at Thales’s radar innovation hub in Limours, the system is designed to be highly flexible and upgradeable. Its software-defined nature allows it to evolve rapidly to counter emerging threats, including potential ballistic or hypersonic weapons, without requiring major hardware overhauls.
- Unprecedented Accuracy: The radar is engineered for the simultaneous, real-time tracking and classification of multiple space objects—including the smallest, most hazardous fragments of debris that could endanger active satellites.
This capability is crucial, as the density of both satellites and debris in LEO continues to soar. As Thales emphasizes, identifying and tracking these small objects in real-time is the key differentiator between vulnerability and sovereignty in modern space operations.
Responding to a Contested Domain
The space domain is increasingly becoming a geopolitical arena. Alongside the persistent risk of accidental collisions, the militarisation of space—including the development of anti-satellite technologies—demands robust, sovereign surveillance capabilities.
AURORE is set to replace and enhance the surveillance pillar of France’s space defense strategy, succeeding the previous generation of sensors like the GRAVES radar. This strategic investment, driven by the French Ministry of Armed Forces, aligns with the objectives of the ARES program and the military planning law (LPM 2024-2030).
The system’s continuous data feed will flow directly to national command centres, ensuring French military forces maintain a precise and autonomous understanding of the low-orbit environment. Furthermore, AURORE is poised to play a major role in the EU-SST (European Space Surveillance and Tracking) consortium, strengthening collaborative European defense initiatives.
🤝 Collaboration and Innovation at the Heart of AURORE
Thales’ success with AURORE is the result of a synergistic effort between industry, government, and SMEs. The Limours site, known for its excellence in radar design, leveraged decades of experience in both civil and military programs.
By partnering with specialized French SMEs, Thales not only boosts national industrial capabilities but also encourages innovation within a robust ecosystem of high-tech companies. This collaborative model strengthens the entire defense sector, ensuring that the knowledge and expertise gained from AURORE will benefit future generations of European radar systems.
« With AURORE, the only radar of its kind in Europe, Thales is contributing to French sovereignty by strengthening its capabilities for monitoring the space environment at low orbits. AURORE demonstrates, once again, Thales’ leadership in the field of air and space surveillance systems.” said Patrice Caine, Chairman and Chief Executive Officer, Thales.
Why AURORE Matters to You
You might be wondering—why should you care about space surveillance? From GPS navigation to satellite communications, weather forecasting, and even financial transactions, modern society depends on satellites functioning safely and reliably.
When space debris or hostile actions threaten these systems, the consequences can ripple through every aspect of our lives. That’s why systems like AURORE matter. They are the silent guardians ensuring that your connections, data, and navigation tools remain secure—even hundreds of kilometers above the Earth.
Frequently Asked Questions on the AURORE Radar and Space Surveillance
AURORE is Europe’s largest and most sophisticated ground-based space surveillance radar, designed by Thales for the French DGA. It is tasked with monitoring satellites and space debris in Low Earth Orbit (LEO) to ensure strategic autonomy.
