Today, the European Union Space Surveillance and Tracking (EU SST) celebrates 10 years of operations, reaffirming its role as a cornerstone of space safety and sustainability.
Since starting service provision on 1 July 2016, EU SST has grown into an essential capability that protects space infrastructure, facilities and services upon which economies and societies increasingly rely. Over the past decade, it has provided three services free of charge - Collision Avoidance, Re-entry Analysis, and Fragmentation Analysis – hence contributing to mitigate risks in an increasingly congested orbital environment.
At the heart of this success lies a strong and effective collaboration between the EU SST Partnership — now comprising 19 EU Member States, up from five in the EU SST Consortium 10 years ago — and the European Union Agency for the Space Programme (EUSPA), which acts as the EU SST Front Desk. This coordinated approach combines sensor, processing and service provision functions into a unified SST capability, showing the value of cooperation at EU level in this domain.
Strengthening the resilience of space assets
Over the past ten years, EU SST has expanded its sensor network, enhanced its data processing capabilities and performed research and innovation activities, enabling better performance and service provision, all while being security relevant, which has ultimately benefitted the EU SST users.
With the number of space objects steadily increasing, EU SST has played a pivotal role in contributing to the resilience of space assets. Its services are provided to all EU Member States and EU institutions, as well as to spacecraft owners and operators worldwide, and other public and private entities.
Key achievements
Over its first decade of operations, EU SST has demonstrated significant growth and impact. Key achievements include:
• over 690 satellites protected from the risk of collision;
• more than 400 organisations registered to the EU SST services;
• two (Collision Avoidance and Re-entry Analysis) of the three services provided to users worldwide;
• a network of over 70 operational sensors (from Member States and commercial) contributing to EU SST, including radars, telescopes and passive ranging systems;
• a very positive feedback received from the EU SST user community.
This underlines the importance of EU SST as an internationally trusted actor in the Space Situational Awareness (SSA) field.
Commenting on the milestone, Pascal Faucher, Chair of EU SST, stated: “Today, we are celebrating a testament to Europe’s commitment to space safety and strategic autonomy. Over the past decade, our partnership has grown stronger, and our capabilities have advanced thanks to our unique approach, which fosters synergies between the civil and defence sectors and strengthens innovation and competitiveness in the European space industry. Together, we reaffirm our dedication to protecting space assets and shaping the future of space safety for generations to come through our public services.”
The way ahead
As EU SST celebrates 10 years of operations, it stands as a flagship example of how the EU successfully works towards an autonomous European capability able to safeguard the European economies, societies and citizens that rely on space-based applications such as communication, navigation and observation.
Looking ahead, EU SST will continue to evolve its functions and strengthen its role as the key operational pillar for the EU Space Traffic Management approach, striving to expand its user base globally and further engaging with international partners – ensuring that space operations remain safe and sustainable.
