RTG LLC
RTG builds systems where embedded software, sensing, communications, edge compute, cybersecurity, and operator software must work together reliably, from edge collection through data normalization, analytics, workflows, evidence, and production transition.
Across all three practices, the same RTG pattern applies: edge evidence becomes normalized data, analytics, operator workflows, cybersecurity evidence, and a practical path toward production transition.
Integrated RF sensing platform and RF-focused practice: SDR-Shark, RF Sentinel, AirScope, Cellular Survey, and Trace Analyzer feeding a shared event plane, with PASSIVE-SHIELD as the mission-oriented passive detection and operator-cueing proof point.
Regulated and cybersecure device systems where embedded software, secure connectivity, platform hardening, updates, evidence, and operator workflows must hold together.
Defense and high-reliability applications of the same foundation: field sensors, passive detection evidence, command-and-control interfaces, telemetry, edge compute, and mission-critical prototypes.

Secure embedded systemsHow Work Starts
RTG engagements usually start with a focused technical output that crosses boundaries: a prototype assessment, collector or event-plane sprint, platform hardening plan, operator workflow, or evidence package that helps a team make a decision, support a review, or move a working system closer to deployment.

Discuss transitionIntegrated RF evidence
RTG Spectrum connects specialized collectors and applications into one reviewable event plane: SDR-Shark, RF Sentinel, AirScope, Cellular Survey, PASSIVE-SHIELD, and Trace Analyzer collect, normalize, correlate, baseline, and surface change across RF, wireless, GPS, cellular, and mission events. PASSIVE-SHIELD remains the defense-facing example of that model: passive DJI/OcuSync-family evidence, acoustic corroboration, station state, map context, and operator cueing brought into a broader sensing workflow.
Defense R&D roadmap
Beyond the current PASSIVE-SHIELD and RTG Spectrum proof artifacts, RTG is developing SBIR-aligned demonstration paths around sensor fusion, mission debrief and replanning, modular event-bus integration, SWaP-optimized edge AI, counter-swarm analytics, and geospatial RF evidence. Those capabilities can be shown with sanitized scenarios, replay data, result cards, and clear claim boundaries before any customer-specific deployment work.
Proof of work
AirScope is a multi-band wireless assurance effort that combines embedded collection, normalized RF evidence, dashboard UX, Pattern-of-Life review, exports, and automated reports. Public screenshots use demo AP names and masked identifiers.
