Atrenne, a Celestica Company, is at the forefront of a major transformation as AI, RF technologies, and SOSA®-aligned architectures converge to redefine how defense systems sense, process, and act on information at the edge.
As military platforms increasingly demand autonomous, intelligent, and distributed capabilities, legacy signal processors and proprietary architectures can no longer keep pace with rapidly evolving electromagnetic environments.
Modern radar, EW, and SIGINT systems must identify and classify complex waveforms, fuse multi-domain data, and deliver actionable intelligence with minimal latency. Traditional fixed-function DSPs and bulky enclosures impede this progress, creating bottlenecks in adaptability, power efficiency, and forward-deployed performance. This shift makes modularity and AI acceleration indispensable.
The Sensor Open Systems Architecture® is accelerating this evolution by standardizing interoperable, upgrade-ready sensor platforms. SOSA-based systems leverage OpenVPX backplanes to integrate scalable RF payloads alongside GPUs, FPGAs, and other AI accelerators, enabling integrators to deploy new processing capabilities without reengineering entire systems. By embracing SOSA, defense programs gain faster technology refresh cycles, reduced vendor lock-in, and significantly improved mission readiness.
AI at the edge further amplifies these benefits. In a SOSA-compliant environment, embedded accelerators enable onboard inference for signal classification, anomaly detection, spectrum threat identification, and geolocation. Applications range from radar systems that autonomously classify moving targets, to SIGINT suites that detect novel or spoofed emissions, to SATCOM terminals that adapt links in response to real-time interference patterns.
Atrenne plays a critical enabling role in this next generation of embedded sensing. The company provides SOSA-aligned backplanes, rugged AI-ready enclosures, and thermally optimized integration designed to support dense GPU and RF workloads. By addressing challenges in cooling, EMI management, and signal integrity, Atrenne delivers the robust physical infrastructure required to deploy high-performance RF and AI processing at the tactical edge.
