The Story
Non-terrestrial networks are becoming a major pillar of the 6G vision, where ubiquitous coverage and service continuity are baseline objectives. Low and very low Earth orbit (LEO & VLEO) constellations are central to this shift, offering low latency, global coverage and scalable capacity.
Yet their performance depends on orbit dynamics, integration with terrestrial systems and signal propagation characteristics. Moving satellites, frequent mobility events, dynamic routing, and the placement of network functions between space and ground all shape the end-to-end experience. No single existing tool brings these elements together in one platform, open to experimenters across Europe.
NEMO-6G aims to close this gap by delivering a software-based emulator that lets ESA and the wider community assess network topologies, protocol stack options and AI-driven control for 6G satellite systems under realistic conditions.
Project Overview
NEMO-6G develops a modular 6G network emulator for NGSO constellations, targeting Technology Readiness Level 4. The emulator supports trade-off analyses of different network topologies, protocol stack functional splits, and regenerative, transparent and hybrid payload options, with end-to-end KPI assessment.
The project has two primary outcomes. The first is a fully operational demonstrator that reproduces the end-to-end system behaviour specified by ESA. The second is a comprehensive evidence package, including source code, configuration packages and test logs, that allows ESA to reproduce reference experiments and confirm compliance with scenarios, KPIs and acceptance criteria.
The emulator builds selected third-party tools for core network functions, RAN prototyping, NTN modelling, orbital dynamics and user equipment emulation. These are integrated into one coherent chain, so every experiment produces consistent, traceable results.
The work is organised in seven Work Packages, from market and technology review through requirements, design, development and integration to demonstration and a future roadmap. It is carried out by Space Hellas (Prime Contractor and ICT systems integrator), the University of the Aegean, Department of Information and Communication Systems Engineering (academic and research partner, and technical coordinator) and FDI (intelligent networking solutions developer).
Our Role in NEMO-6G
Four Dot Infinity (FDI) plays a central role across the full project lifecycle, from the technology foundations to the final integrated demonstrator.
Impact and Expected Outcomes
NEMO-6G delivers a validated, reproducible foundation for designing and testing 6G satellite networks.
