Mission Domains
Built where information becomes action.
From airborne platforms and expeditionary communications to cyber defense and secure infrastructure, OSS engineers systems intended to perform when conditions are least forgiving.
Mission Intelligence
Turning telemetry and operational data into timely, decision-ready information for complex mission environments.
Connected Operations
Reliable signal processing and communications architectures designed to keep critical users connected anywhere.
Cyber Resilience
Security engineering, detection, monitoring, automation, and resilient infrastructure for systems that cannot afford to fail.
Since 1974
A legacy of quiet innovation.
Obsidian Signal Systems began with three former military officers, surplus electronics, and a belief that better engineering could solve problems others considered too difficult or too inconvenient. Five decades later, that principle still guides our work.
Our name may not be as recognizable as the largest primes. That's intentional. We don't make headlines. We make a difference.
