Military PCE Unit – Real-Time Communication Gateway

Context & Challenges

In the defense sector, every microsecond matters.

Embedded systems must not only operate continuously but also withstand extreme environments: vibrations, thermal shocks, electromagnetic disturbances, network interference, and more.

A major defense contractor approached Dunasys to develop a real-time communication gateway capable of unifying multiple CAN and Ethernet networks within a mission-critical architecture.

The objective was to ensure secure, consistent, and instantaneous communication between essential subsystems used in operational environments.

The key technical challenges identified were:

• Ensuring deterministic bidirectional communication with no latency and no data loss.
• Withstanding military-grade electromagnetic constraints and harsh operational environments.
• Integrating a high level of cybersecurity to protect sensitive communications.
• Ensuring system certifiability in accordance with defense industry standards.

Our Contribution

Dunasys designed and developed a real-time communication gateway based on a highly optimized embedded architecture.

The solution provides:

• Instantaneous and reliable communication between CAN and Ethernet networks, even under heavy traffic loads.
• Enhanced immunity to electromagnetic disturbances through dedicated hardware design.
• Comprehensive communication security, including encryption, authentication, and traceability.
• Full compatibility with the customer’s existing protocols and equipment.

This project also enabled our teams to further strengthen our quality and security maturity through:

• Dedicated internal training on military standards and methodologies covering quality assurance, software security, and traceability.
• Upgrades to our design, validation, and documentation processes.

Results & Added Value

• A robust, certifiable, and auditable architecture that meets the requirements and standards of defense authorities.
• Enhanced expertise in software security and industrial traceability.
• Recognition of our know-how in mission-critical environments.

Conclusion

This achievement is fully aligned with Dunasys’ ongoing involvement in critical sectors such as Defense, Rail, Aerospace, and Advanced Mobility.

It demonstrates our ability to support customers on highly demanding projects where every detail matters and where innovation serves the mission.

When the mission allows no room for failure, technology must be flawless. Dunasys designs solutions that are ready for deployment in the most demanding environments.
