GP-Jammer

Advanced RF Jamming Simulation Made Simple

GP-Jammer is a powerful RF jamming and interference simulation platform designed for researchers, engineers, and system integrators.

Built on an open-source Python framework and optimized for SDR hardware, GP-Jammer enables precise, scalable, and cost-effective testing of communication and navigation system resilience.

From wideband interference to sophisticated “smart” jamming scenarios, GP-Jammer provides the tools needed for in-depth analysis and realistic simulation—without the complexity or processing overhead of traditional solutions.

Why Choose GP-Jammer?

GP-Jammer combines flexibility, performance, and scalability into a single software platform, making advanced RF interference testing accessible and efficient.

Wide Frequency Range for Comprehensive Testing

GP-Jammer supports RF jamming simulation from 70 MHz to 6 GHz, covering most modern communication and navigation bands.

Up to 56 MHz signal bandwidth per channel
Powered by custom firmware for Adalm Pluto SDRs
Ideal for wideband and multi-band interference scenarios

This wide frequency coverage enables realistic testing across GNSS, cellular, ISM, and other critical RF systems.

Advanced Interference & Jamming Signal Library

At the core of GP-Jammer is a growing library of complex, high-fidelity jamming waveforms, fully implemented in Python.

Smart jamming and adaptive interference patterns
