CNES contributes to the development of skills in the armed forces and commits all its expertise to the development of future military space capabilities. As part of the 2026 exercise, our experts in space surveillance, operations and flight dynamics are participating in the development of the exercise scenario. They then break down the various orbital threats (aggressive approaches, collision avoidance, etc.) into technical data in the simulation environment. Some also participate as players during the exercise.

The NATO Space Centre of Excellence (COE) aims to be a key catalyst for the comprehension, improvement, and transformation of Space Power by delivering effective solutions and providing relevant expertise to the benefit of NATO and its Allies. The Centre is acting as Department Head for the Space discipline, and as Custodian for the drafting and updating of the NATO Doctrine for Space Operations (AJP 3.29).

In support of SparteX, the NATO Space COE participates in the exercise as a player and takes part in the Lessons Learned part.

Since the creation of the SparteX exercise, ONERA has been providing the CDE with its expertise in the field of space surveillance.
ONERA simulates all state and industrial surveillance resources, thereby guaranteeing the quality and consistency of the measurements produced during the exercise. ONERA also guarantees the representativeness of the scenarios by providing a complete catalog of objects tracked by the GRAVES system.
It recently added realistic simulation of objects seen from the ground using a 2.5-meter diameter adaptive imaging telescope (Providence).

AGENIUM develops space surveillance solutions covering Space Situational Awareness (SSA) and Space Domain Awareness (SDA) for ground and onboard systems. These solutions support operational decision-making through trajectory, threat and vulnerability analysis. For onboard SDA, AGENIUM offers an AI-based Space-Based Space Surveillance (SBSS) capability enabling threat detection and classification, as well as alert triggering.

Crisotech by ChapsVision is the Chapsvision entity specialized in crisis management and crisis communication consulting and training, with recognized expertise in designing and delivering high-impact crisis exercises. A trusted partner of the CDE since the inaugural AsterX edition in 2021, Crisotech by ChapsVision plays a key role in the overall scenario coordination, while also leading the design and facilitation of the open-source intelligence component.

Holograph is at the heart of AsterX 2025 and space operations. Multi-domain operations planning software compliant with NATO standards, Holograph aims to enhance command performance.

Holograph enables all AsterX 2025 expertises to contribute together at each stage of the Plan, from mission analysis to produce orders and synchronize effects. Enhanced by generative AI, Holograph offers next-generation capabilities to accelerate processes, inform decision-making, and master the complexity of operations.

Look Up, a key player in space surveillance (SSA/SDA), contributes to the SparteX 2026 exercise by providing operational space situational awareness capabilities. 

Its SORASYS radar network delivers precise and sovereign measurements, enabling the detection and tracking of small objects with a high revisit rate. Its SYNAPSE multi-source data fusion digital platform processes these data to deliver advanced analytics, near real-time situational awareness, and decision-support insights in support of the exercise scenarios.
