GP-Jammer is a software tool designed for wide-band RF jamming simulation. It leverages an open-source Python library to produce a variety of interference signal types, including complex modulations for “clever” jammer simulation. GP-Jammer enables researchers and engineers to conduct comprehensive studies on the impact of different interference patterns on communication and navigation systems, facilitating advanced testing and analysis of system resilience and performance.
Utilize a fully open-source Python library for sophisticated signal generation, allowing users to customize and adapt interference patterns as needed.
Custom firmware for Adalm Pluto allows IQ samples to be preloaded into SDR memory and played in a continuous loop. This approach eliminates the need for real-time IQ data calculation and streaming.
With custom firmware for Adalm Pluto SDRs, GP-Jammer covers 70 MHz to 6 GHz with up to 56 MHz signal bandwidth per channel, enabling comprehensive interference testing.
With no load on the computer’s processor, the software can manage an unlimited number of connected SDRs at once. This makes our solution both unique and highly cost-effective for multi-band jamming simulations.
Create broad-spectrum jamming setups at the lowest possible cost, with each channel costing only $250 using Adalm Pluto SDRs.
The software includes a library of unique, complex jamming signals written in Python, allowing you to unleash your creativity and tailor interference patterns to your specific testing needs.

Create custom modulations using the open-source Python library to meet your specific testing needs.
The Adalm Pluto SDR synthesizes the RF signal by continuously playing preloaded IQ data, which is generated by a Python script and saved as a binary .iq file. This IQ data is transferred to the SDR, where it is looped, effectively reducing system load by eliminating the need for real-time streaming.
