Across today’s global defence and security environments, operational success depends on technologies that can connect, process, and communicate data reliably, from the tactical edge to larger modular system architectures.
At Eurosatory 2026, Sealevel will join our Steliau Italy partner, represented by Hi-Rel Solutions by Steliau Technology, to showcase rugged embedded computing and I/O solutions that support resilient operations, integration, and interoperability in demanding applications.
Built for reliability. Designed to integrate. Ready to scale.
COTS-Based Modularity for Defence Modernisation
Defence programmes are under pressure to modernise faster while maintaining reliability, interoperability, and lifecycle control. Sealevel supports this need with rugged COTS and configurable embedded compute and I/O technologies that serve as modular building blocks within larger platforms, test systems, communications equipment, unmanned systems, and operational support infrastructure.
Reduce System
Integration Time
Use proven COTS hardware foundations to accelerate system development and reduce redesign complexity.
Support Modular
Architectures
Combine compute, I/O, expansion, and communication interfaces to support evolving system requirements.
Bridge Legacy and
Modern Systems
Connect existing equipment with newer embedded platforms through reliable I/O and communication interfaces.
Scale from Standard
to Custom
Adapt standard platforms through Sealevel’s in-house engineering, manufacturing, and lifecycle support.
Technologies Designed for
Multi-Domain Defence Applications
Capability 01
Rugged Embedded Compute
Sealevel rugged embedded computers support reliable edge processing, data handling, and system control in demanding defence, aerospace, and industrial environments. Built for long lifecycle deployment, these platforms help bring compute closer to sensors, equipment, and control systems where space, power, and environmental constraints matter.

- x86-based industrial computers
- COM-based embedded architectures
- SWaP-conscious designs for constrained deployments
Capability 02
I/O & System Connectivity
Modern defence systems depend on reliable connections between sensors, controllers, communications equipment, and compute platforms. Sealevel I/O solutions help integrate real-world signals and legacy or modern devices into distributed architectures that support interoperability, control, and data acquisition.
- Digital, analog, serial, USB, Ethernet, and CAN interfaces
- PCIe, USB, and Ethernet expansion options
- Sensor, peripheral, and control system connectivity
- Standard and application-specific I/O configurations
Capability 03
Communications & Data Interfaces
From tactical edge systems to larger open architectures, dependable communication pathways are essential to moving data where it is needed. Sealevel communication interfaces support connectivity, signal conversion, and data transfer across embedded systems, test environments, unmanned platforms, and operational support equipment.
- Interface conversion and protocol bridging
- Low-latency data acquisition and device communication
- Connectivity for distributed and modular systems
