GRX3X
The GRX3X is a flexible multi-band receiver designed to support surveillance monitoring, spectrum monitoring, and advanced measurement applications in a single device. Its modular architecture allows up to three independent radio front-ends to operate simultaneously, enabling monitoring across multiple aviation frequency bands with one integrated sensor.
Designed for surveillance, research, spectrum monitoring, and advanced surveillance applications, the GRX3X supports simultaneous reception of all surveillance bands and the broader RF spectrum while providing access to raw signal data for advanced analysis. The platform’s configurable modular architecture allows customers to tailor the receiver to their specific surveillance, spectrum-monitoring, or experimental measurement requirements.
