Tenna Systems - software-driven spectrum intelligence
Tenna Systems is a defense-focused technology company specializing in spectrum intelligence and RF emitter geolocation, designed for operations in contested electromagnetic environments. Its core value lies in transforming GNSS interference, traditionally a disruptive and unpredictable threat into a trackable, actionable, and ultimately targetable domain for military and operational users.
At the heart of Tenna’s offering is a software-defined architecture that avoids reliance on new hardware deployments. Instead, it leverages existing commercial and government sensor networks to create a unified, real-time picture of the RF battlespace. This approach significantly reduces deployment time and cost while enabling rapid scalability across operational units.
The company’s primary products, ARENA and TRACER, work in tandem to deliver persistent electromagnetic awareness and precision geolocation. ARENA provides near real-time mapping of GNSS degradation, identifies multiple emitters across an area of operations, and visualizes the electronic order of battle within a common operating picture. This gives operators continuous visibility into contested spectrum environments. TRACER builds on this by geolocating interference sources in two phases: first, rapidly identifying general locations across a wide area, and then refining those detections into targeting-grade precision (as accurate as 10-50 meter CEP).
Operationally, Tenna’s capabilities are integrated across ISR, electronic warfare, and mission planning workflows. Forces can detect and visualize interference, classify threats, adapt missions in real time (such as rerouting UAVs), and ultimately convert RF signals into actionable targets. The system also supports battle damage assessment by continuously monitoring emitter activity after engagement.
The impact is a shift from reactive to predictive operations. Instead of operating blind in degraded GNSS environments, users gain persistent awareness, enabling them to anticipate threats and maintain mission continuity. By fusing data across air, ground, maritime, and space domains, Tenna delivers a comprehensive and evolving understanding of the electromagnetic battlespace.
In practical terms, Tenna Systems enables military operators to maintain spectrum superiority, reduce mission risk, and directly support targeting and strike operations, all without the burden of deploying new hardware.
