One platform. Every signal. Every stage.
Sceptre spans the entire workflow — from the moment a signal first appears, through analysis, and out to action.
Detect & Identify
Signal discovery, masking, and emitter classification — prioritize and assess incoming signals to rapidly surface the most critical threats.









Extract & Analyze
Signal extraction, characterization, and in-depth analysis — isolate and extract signals of interest, then analyze their parameters, behavior, and emitter characteristics — with pulse archive and decision-quality data for after-action review.











Locate & Track
Geolocation, heatmapping, and direction finding — commercial-off-the-shelf TDOA/FDOA geoengine and direction finding capability to pinpoint and pursue emitter sources.






Decide & Act
Cueing, intercept, and remote operations — operate Sceptre remotely — even over bandwidth-constrained links — and feed the response directly into existing systems.
