Signal Detection
Blind, multi-scale detection of known, unknown, intermittent, and frequency-hopping transmissions — down to 0 dB C/N and below the noise floor.

Digital Processing for Signal Intelligence
Advanced software and integrated systems that let operators detect, identify, analyze, geolocate, monitor, and exploit complex radio and satellite communications.
Core capabilities 07 disciplines
From raw spectrum to actionable intelligence.
NovaGrid engineers the full chain — detection, analysis, geolocation, and monitoring — around blind digital signal processing that assumes no prior knowledge of the signals it encounters.
Signal Analysis
Automatic identification of modulation, constellation, coding, framing, and MAC protocols, with estimation of symbol rate, bandwidth, SNR and Eb/N₀.
Passive Geolocation
TDOA/FDOA hyperbolic geolocation of transmitters relayed by satellite transponders, with co-orbit estimation and reference-free operation.
Satellite Payload Monitoring
2D time-frequency carrier & spectrum monitoring across full transponders, comparing live measurements against the declared mission plan.
Spectrum Surveillance
Continuous wideband surveillance with autonomous noise-floor estimation, interference and jammer characterization.
Mission Planning
A high-level planning environment where operators configure missions — not signal-processing algorithms.
Simulation
Full PHY and MAC radio-scene simulation for algorithm development, system validation, and operator training.

Configure missions,
not algorithms.
NovaGrid's software ecosystem is called HyperSuite. Its major advantage is a high-level mission-planning environment: operators express operational intent, and the platform handles the signal processing beneath it.
Mission-oriented configuration
Operators describe what to monitor, geolocate, or analyze. The platform derives the signal processing.
Shared workflows
HyperMon Planner, HyperLoc Planner, and HyperCSM Planner share nearly identical workflows and interfaces.
No DSP expertise required
Unlike traditional DSP software, operators configure missions rather than algorithms — the learning curve stays shallow.
One unified experience
A common philosophy across every HyperSuite application reduces training, deployment time, and operational risk.

HyperSpectrum
The shared planner workflow drives HyperMon, HyperLoc, and HyperCSM. Learn one, operate all — training time and deployment risk drop accordingly. HyperStream, HyperSim, and HyperSpectrum operate as standalone tools alongside the suite.
Hardware solutions Since 2015
Turnkey systems,
deployable in hours.
Each system combines optimized COTS hardware, preconfigured HyperSuite software, calibration, installation, and remote support. Connect antenna feeds and network, describe the station, and operate remotely from any workstation.
