Latest Patents

Diaz is named on 1 patent: “System and Method for Global Navigation Satellite System (GNSS) Spoofing Detection.” The invention formulates an optimization problem using baseband correlator outputs and may apply an algorithm such as Least Absolute Shrinkage and Selection Operator (LASSO). It builds a dictionary of precomputed waveform functions to model the intended signal, then uses sparse signal processing to identify a decomposition that can distinguish authentic and spoofed code-phase values. A threshold can help mitigate false alarms, and a variation of the optimization method can use a higher-resolution dictionary.

Career Highlights

The patent reflects work on signal-processing techniques for identifying potential GNSS spoofing. By analyzing correlator outputs and distinguishing signal peaks, the method is designed to support detection of deceptive signals that could affect navigation systems.

Collaborations

The patent’s listed collaborators include David Akopian and Nikolaos Gatsis. The work is associated with The University of Texas System.

Conclusion

Erick Schmidt Diaz’s patent focuses on using optimization and sparse signal processing to detect and classify GNSS spoofing, contributing a technical approach to navigation-signal security.
