At ESA, through the Advanced Research in Telecommunications Systems programme, we’re addressing solutions for when safety and security of communication services cannot be guaranteed by the terrestrial networks alone. With our programme Space systems for Safety and Security, or 4S, we are pioneering cutting-edge development of secure and resilient satellite communication systems, technologies and services to improve life on Earth.
Picture a world where our critical infrastructure is protected from cyber threats, and where communication links work when the world around them doesn't. A transportation network where safety is not just a priority, but a guarantee. Where air traffic flows completely efficiently, reliable and connected. Railways operate without interruption, and shipping can navigate safely and securely.
Imagine that our first responders are coordinating via seamless communications, and institutional agencies are acting rapidly and decisively when there's a crisis. All thanks to secure and safe satellite communication systems, orbiting above the planet. This is the future we're building with the 4S programme. A future where space systems safeguard our security, making sure that connectivity remains our greatest strength. Join us as we continue to push the boundaries of innovation.
