Embedded systems for defense
Onboard intercom systems for military vehicles, electronic boards for naval programs, crisis rooms, and command posts. Designed for extreme environmental conditions, continuous operation, and long lifecycles.
— The context
Onboard communication systems in vehicles, ships, and command centers operate in extreme environments: vibrations, temperatures, EMC, shocks, and salt spray. Operating lifespans exceed 20 years. They require material sovereignty, long-term component sourcing, and retrofit capability.

— Frequently asked questions
Your questions
(*)
We qualify our products against the standards applicable to each program: vibration, shock, temperature, electromagnetic compatibility, electrical protection, and resistance to extreme environments. Every qualification is tied to the product and documented.
(*)
Yes. Our IP gateways connect existing radio infrastructure (TETRA, UHF, VHF, HF sideband) to modern architectures without full replacement. Gradual retrofit compatible with scheduled maintenance windows.
(*)
Design and manufacturing in Élancourt (France), continuous component monitoring, anti-obsolescence plan from the design stage, prioritized French and European sourcing for critical components. We sustain the long lifecycles that international manufacturers do not commit to.
(*)
Milesys operates within a clearance framework that allows for the design and delivery of equipment for sensitive programs. Specific terms are arbitrated case by case with the program direction.
(*)
Yes. Our equipment integrates with existing defense communication architectures, including interoperable software suites. Our terminals provide the radio mixing and audio quality required for command centers. Interfaces and protocols are scoped during the engineering phase.
(*)
Long-term lifecycle support contracts, direct access to engineering support, comprehensive documentation, and source code access for embedded firmware when relevant. Field feedback is processed through our ISO 9001:2015 quality loop.
(*)
Yes. Our engineering team handles custom projects every year for defense integrators and prime contractors. Three integrated engineering teams (electronics · real-time software · mechanics). Off-the-shelf components for non-critical elements, targeted design where it matters.
(*)
Yes. Complete suites: IP intercom, operator stations, radio gateways (TETRA, UHF, VHF, HF sideband), supervision, audio recording synchronized with video surveillance.
