RTG Spectrum

Modular RF sensing and analysis platform.

RTG Spectrum combines specialized collectors and applications into one shared event/data plane: collect, normalize, correlate, establish baseline, detect change or anomaly, and support operator decisions across RF, wireless, GPS, cellular, and mission events.

Discuss RF Sensing Explore Platform

One platform pattern: collect, normalize, correlate, baseline, and detect change.

Collect & Classify

Specialized modules collect RF, WiFi, BLE, GPS, spectrum, and mission cues from SDRs, radios, edge devices, and prototype sensors, then turn observations into classifier-ready evidence.

RF signal classification software

Normalize

Application-specific events are converted into a shared, source-aware event model with timestamp, protocol, identity, signal, and raw detail.

Shared event plane

Correlate & Baseline

Trace Analyzer and module analytics connect events across tools to establish normal patterns, recurring entities, location-aware context, and operational context.

Geospatial RF analytics

Detect Change

Pattern-of-Life workflows surface new, missing, recurring, anomalous, or mission-relevant activity so operators can decide what deserves attention.

Mission cueing

Built for teams that need a working RF sensing ecosystem, not isolated demos.

SDR-Shark, RF Sentinel, AirScope, Cellular Survey, PASSIVE-SHIELD, and Trace Analyzer are presented as modules in a broader sensing and analysis platform. Each module has a job: collect a specific class of evidence, publish normalized events, preserve source context, and feed shared analysis that helps teams understand baseline behavior and detect meaningful change.

How Engagements Start

Start with an assessment, integration sprint, or prototype pilot.

RTG Spectrum accelerates paid RF assessments, sensor integrations, and prototype pilots using an existing modular sensing and analysis foundation.

RTG Spectrum is also the public-safe showcase layer for adjacent defense technology work: parallel sensor fusion, mission debrief and replanning, modular event-bus integration, counter-swarm analytics, geospatial RF evidence, and operator decision support. The right public format is a sanitized demo, replay fixture, result card, or case study with clear boundaries around what is proven and what is not claimed.

Flagship demo

SDR-Shark demonstrates the spectrum collection side of the platform.

SDR-Shark is packaged with deterministic synthetic IQ replay data, Docker Compose startup, replay APIs, and a browser interface for watching Bluetooth-like frequency-hopping signal behavior, FFT, waterfall, and signal-activity workflows. In the Spectrum platform story, it is a collector and analysis module feeding evidence into broader normalization and operator workflows.
