An increased number of GPS jamming and spoofing attacks have been reported and documented over the past five years. With high-quality software-defined radios (SDRs) becoming more affordable, hardware capable of GPS jamming and spoofing is more available than ever. It is critical to test your PNT systems against these attacks. BroadSim is a software-defined GNSS simulator that enables users to easily model true and spoofed signals.
BroadSim is revolutionizing the way in which GNSS testing and simulation is performed yet again by enabling the simultaneous generation of jamming signals and GNSS signals all in one system. Generate complex spectrums by leveraging BroadSim’s 4 Tx outputs. BroadSim is capable of generating high fidelity jamming and interference signals of multiple types, provides Intuitive control using Skydel software and utilizes 4 RF outputs, each with multiple simultaneous constellations.
Old jamming testing method without BroadSim
Users required to attach a separate signal generator for each interference waveform to be generated
The number of interference sources is limited to the number of signal generators available
Signal generators would need to be integrated into software or be operated real-time by an engineer
Jamming power levels were determined based on what signal level was to be received at the receiver front end independent of the location of the simulated jammer or transmit power
New jamming testing method with BroadSim
Unlimited number of interference signals can be generated with 1 RF output
Each interference signal within 1 RF output can have different power levels, modulations, and locations
Jamming can be turned on and off through the SDX GUI and API
Users can specify the location and power of jamming transmitters and BroadSim will calculate the received power at the receiver based on the location to the transmitted and user-selected loss model
Enables users to create real-world threat laydowns to better support the warfighter.
