Cognitive Cloud Computing in Space for Earth Observation (3CS4EO)

This project focuses on space-cloud architecture study.

ESA Phi-lab records 3CS4EO as a Telespazio feasibility study conducted from July 2025 through September 2026. The study developed a two-satellite Leader-Follower architecture for onboard Earth-observation processing, user-deployed PaaS applications, autonomous Tip-and-Cue operations, optical intersatellite connectivity and direct-to-user alerts. It is a completed architecture study, not a launched or operating constellation.

ESA records 3CS4EO cognitive cloud study and its two-satellite architecture (opens in a new tab)

ESA Phi-lab records the completed July 2025 to September 2026 Telespazio 3CS4EO feasibility study. Its two-satellite Leader-Follower concept combines onboard high-performance computing, a user PaaS, AI processing, optical intersatellite connectivity, autonomous Tip-and-Cue operations and direct-to-user alerts. Named Unibap Hailo-8 and NVIDIA Jetson development packages are study outputs, not selected flight hardware.
