IN Brief:
- Eviden has presented an integrated defence portfolio spanning electronic intelligence, command systems, and tactical connectivity.
- Drone-carried ELINT sensors and AI-supported analysis are intended to accelerate emitter detection and threat assessment.
- Secure gateways, radios, and data systems reflect the shift towards connected multi-domain defence architectures.
Eviden has assembled electronic-intelligence sensors, tactical command systems, secure communications, artificial intelligence, and protected data exchange within a connected defence portfolio presented at Eurosatory 2026.
The systems cover the path from detecting activity within the electromagnetic spectrum to distributing information through command networks. Technologies displayed in Paris included signals-intelligence sensors, electronic-support and electronic-intelligence equipment, tactical radios, command-and-control software, navigation tools, security modules, and gateways for moving information between differently classified systems.
Avantix, Eviden’s electronic-warfare business, presented ELINT equipment intended for integration with uncrewed aircraft. The payloads are designed to detect, identify, and geolocate hostile emitters, allowing a smaller airborne platform to contribute to the electronic order of battle without placing a crewed aircraft close to the source.
Artificial intelligence can support the sorting of captured data, prioritisation of alerts, and initial assessment of detected signals. Automated processing can manage volume and repetition, while trained analysts retain responsibility for interpretation, confidence assessment, and operational action.
At command level, the portfolio includes SICS as a digital backbone for collaborative combat, alongside the P3TS positioning and navigation system, ECHO tactical IP radio, and Digital Soldier System. Multi-level security gateways, hardware security modules, and key-management technology govern how information is protected and exchanged.
Each layer depends on the integrity of the others. A sensor may detect an emitter accurately, but the information has limited operational value unless timing, location, confidence, and classification can be processed and delivered to the correct system without losing context.
Recent work on cyber protection within military platform engineering follows the same architectural direction, embedding security controls into vehicles, aircraft, sensors, and command systems instead of treating them as later additions.
Electronic warfare receivers must now operate in a crowded spectrum containing military, commercial, and dual-use signals. Emitters may transmit intermittently, change frequency, reduce power, imitate expected traffic, or use waveforms intended to complicate identification, placing greater demands on instantaneous bandwidth, dynamic range, timing accuracy, and onboard processing.
Uncrewed platforms alter the balance between coverage and payload constraint. Distributed drones can approach emitters from several directions and increase geolocation opportunities, but available mass, electrical power, cooling, antenna aperture, data-link capacity, and computing resources remain tightly limited.
More filtering and feature extraction are consequently moving onto the sensor platform. Local processing can reduce the volume carried over a contested link and preserve some capability during communications interruptions, although models, signal libraries, and mission data require secure configuration and controlled updates.
As detections move between systems, common data structures and timing discipline preserve their usefulness. A report that loses sensor identity, time reference, coordinates, or confidence may add confusion to the operating picture, particularly during coalition operations involving equipment from several nations.
Multi-level security gateways address the practical restrictions created by classified and releasable information. Policy must be enforced without discarding essential operational content, while hardware security modules protect cryptographic processing and key material from compromise.
Validation increasingly extends beyond connecting finished systems on a range. Digital-network twins and high-fidelity hardware emulation can exercise communications, radar, electronic-protection, and cybersecurity behaviour against repeatable threat environments before full field trials.
The expansion of Keysight and Leonardo test services in the UK reflects the growing need to validate complex RF and defence systems through controlled laboratory infrastructure. As interfaces multiply, repeatable emulation helps identify faults that may be difficult to isolate during an expensive multi-platform exercise.
Battlefield electronics are increasingly judged by the behaviour of the complete information chain rather than standalone sensor or radio performance. Eviden’s portfolio connects collection, analysis, command software, communications, and security within that chain, where a capable receiver remains ineffective if its data cannot be trusted, transported, fused, or protected.
