GNSS Spoofing Scenarios
Our GNSS Interference SDR Toolkit is capable of simulating a wide range of GNSS spoofing scenarios to meet diverse testing and development needs:
- Static Spoofing: Simulates fixed-position spoofing attacks where the false GNSS signals suggest a constant, incorrect location.
- Dynamic Spoofing: Generates spoofing signals that mimic movement, causing the target receiver to perceive erroneous changes in position or velocity.
- Coherent Spoofing: Produces synchronized spoofing signals that align precisely with legitimate GNSS signals, making detection more challenging.
- Asynchronous Spoofing: Introduces unsynchronized spoofing signals, which can be used to test a receiver’s ability to detect and mitigate such discrepancies.
Beamforming Technology
Our GNSS Interference SDR Toolkit enables the synchronization of multiple connected SDRs, forming a large phase-coherent array. This configuration allows for the creation of antenna arrays in various formations, such as 2×2, 4×4, or 16×16, facilitating advanced beamforming capabilities. By precisely controlling the phase and amplitude of signals across the array, users can direct interference patterns with high accuracy, enhancing the effectiveness of jamming and spoofing scenarios.
