Targeting the operational security and verification vulnerabilities of scaling multi-orbit satellite networks, Keysight Technologies, Inc. has been selected by the European Space Agency (ESA) to lead a three-year development program focused on secure, blockchain-enabled anomaly detection for 5G Non-Terrestrial Networks (NTN).
Keysight will serve as the prime contractor for the initiative, collaborating with Spanish satellite operator Sateliot to execute technical development and core satellite mission integration.
Architectural Metrics and Blockchain Trust Framework
The program aims to embed cryptographically verifiable tracking methods across the entire lifecycle of non-terrestrial infrastructure to prepare hybrid topologies for next-generation 6G operations:
- Lifecycle Coverage: Integrates digital calibration certificates, blockchain ledger verification, and artificial intelligence (AI)/machine learning (ML) architectures across satellite manufacturing, initial component calibration, in-orbit telemetry routing, and end-user service delivery.
- Anomaly Mitigation: Focuses on real-time cyber defense mechanisms engineered to protect massive Internet of Things (IoT) and 5G networks against signal spoofing, data tampering, and localized malicious interference.
- Telemetry Verification: Establishes a decentralized trust layer to ensure that operational data used by autonomous, AI-driven network management centers remains uncompromised.
Program History and Regional Funding Structures
The development project is funded under the Space for 5G/6G & Sustainable Connectivity program line within ESA’s Advanced Research in Telecommunications Systems (ARTES) Strategic Product Line. This initiative builds directly on recent technical milestones achieved by both commercial partners under ESA guidance.
Notably, the selection follows an early April 2026 milestone where Sateliot and Keysight were jointly awarded the ESA and GSMA Foundry Challenge for initial conceptualizations of blockchain-backed anomaly detection. The project expands on Keysight’s separate January 2026 technical collaboration with Airbus UpNext on the SpaceRAN LEO demonstrator platform, as well as Sateliot’s February 2026 dual-mode 3GPP Release 17 integration contract executed with LMT Group.
Executive Perspectives on Orbital Validation
The integration of distributed ledger structures into satellite systems marks a strategic shift intended to provide transparent verification tools for enterprise users operating cross-border IoT tracking fleets.
“This program represents a definitive shift toward integrating space-based assets into a secure, unified 5G ecosystem,” stated Albert Pujol, Chief Innovation Officer at Sateliot. “By anchoring blockchain within our orbital operations, we are creating a transparent validation layer that allows massive IoT networks to scale globally while consistently ensuring security and performance.”
Development Schedule and In-Orbit Demonstration
The three-year development roadmap is structured to transition from early-stage laboratory prototyping and software emulation environments to active field validation. The program will culminate in a comprehensive in-orbit demonstration using an operational Sateliot spacecraft to validate the performance of the blockchain trust architecture under real-world orbital dynamics and propagation constraints.
