Objectives
The REGINA project aims to develop advanced RRM techniques to mitigate jamming threats in NGSO constellations and improve the resilience of future satellite communication systems. The primary objective is to design intelligent RRM algorithms capable of dynamically allocating network resources in response to unexpected jamming events, thereby maintaining service continuity and communication reliability.
To achieve this, the project investigates strategies that exploit satellite diversity, adaptive handover mechanisms, and coordinated resource allocation across multiple satellites and users. These mechanisms enable the network to rapidly reconfigure communication links, redistribute traffic, and mitigate interference caused by jammers.
REGINA also aims to ensure that the proposed solutions are scalable and compatible with current and emerging satellite technologies, including standards such as DVB-S2X, DVB-RCS2, and 3GPP NR-NTN. The project therefore focuses not only on algorithm design but also on system-level integration and validation.
Another key objective is to evaluate and verify the developed techniques through simulations and a system testbed, assessing their performance under different jamming scenarios and operational conditions. Finally, the project seeks to advance the technology readiness level (TRL) of the proposed solutions and define a roadmap toward industrial deployment, ensuring practical applicability in future NGSO satellite networks.
Challenges
The REGINA project addresses several challenges related to jamming mitigation in NGSO satellite networks. These include detecting and characterizing diverse jamming strategies in highly dynamic multi-satellite environments, coordinating mitigation actions across satellites with limited onboard resources, and adapting resource allocation in real time without disrupting ongoing services. Additional challenges arise from the rapid topology changes of NGSO constellations, the need for GNSS-independent synchronisation under jamming conditions, and ensuring compatibility with existing standards such as DVB-S2X, DVB-RCS2, and 3GPP NR-NTN. Finally, validating the proposed solutions through realistic simulations and testbed experiments while maintaining scalability and practical deployability remains a significant challenge.
System Architecture
The REGINA system architecture follows a multi-layer, system-level design that integrates satellites, gateways, and user terminals to support coordinated jamming detection and mitigation in NGSO satellite networks. The architecture enables both uplink and downlink resilience mechanisms through distributed sensing and centralised coordination.
At the user segment, terminals perform local signal monitoring and provide measurements related to interference conditions, such as received signal quality and spectrum observations. These measurements support user-assisted jamming detection and enable adaptive connectivity decisions, including satellite or beam switching when interference is detected.
At the satellite segment, onboard processing and network coordination mechanisms aggregate information from multiple users and beams. This layer enables cooperative mitigation strategies, such as dynamic beam reconfiguration, adaptive resource allocation, and multi-connectivity management across satellites.
At the ground segment, gateways host the RRM and coordination engine, which processes network-wide information and orchestrates mitigation actions across the constellation. This includes traffic redistribution, spectrum reassignment, and coordinated responses to jamming events.
Plan
The project is organised into eight work packages (WPs), seven technical WPs and one management WP. The work progresses from scenario definition and requirements analysis to the design and implementation of the system-level demonstrator and performance validation. Milestones correspond to project meetings, including the kick-off meeting, periodic progress meetings, technical review meetings, and the final review meeting. Deliverables consist of technical notes (TN0, TN1, …, TN6), software components (SW1, SW2, and SW3), and datasets supporting algorithm development and validation. This structure ensures continuous monitoring of progress and systematic validation of the developed solutions.
Current Status
The project has been kicked off and the currently TN0 and TN1 are in progress.
