Summary

A novel method for compressing and classifying Global Navigation Satellite System (GNSS) jamming threats utilizes generative artificial intelligence (GenAI), specifically variational autoencoders (VAEs), deployed on Google Edge TPUs. This approach addresses the need for real-time, power-constrained solutions by efficiently compressing GNSS data streams and simultaneously classifying jamming and spoofing attacks directly at the hardware receiver. The system evaluates various autoencoder architectures to preserve interference characteristics while minimizing data size, adapting large-scale AE models for Google Edge TPUs via 8-bit quantization. Tests on raw in-phase and quadrature-phase (IQ) data, Fast Fourier Transform (FFT) data, and handcrafted features demonstrate significant compression (>42x) and accurate classification of approximately 72 interference types on reconstructed signals (F2-score 0.915), closely matching original signals (F2-score 0.923). This hardware-centric GenAI approach also reduces jammer signal transmission costs.

Key takeaway

For AI Engineers developing GNSS interference mitigation systems, this research demonstrates a viable path to real-time, on-device processing. You should consider integrating 8-bit quantized VAEs on Google Edge TPUs to achieve substantial data compression and accurate classification of jamming signals, thereby reducing transmission costs and power consumption in critical applications.
