This straightforward presentation, crafted for the Time Appliances Project, delves into the practical methods of detecting anomalies in raw GNSS data to combat GNSS spoofing. We'll touch on everything from interference types to the latest in spoofing defense.
Covered topics:
• Techniques to protect critical infrastructure from GNSS spoofing.
• The Escalation of GNSS Spoofing Incidents Globally.
• Types of spoofing: coherent and non-coherent attacks.
• Data for Analysis: Reviewing the NMEA and UBX protocols.
• Coordinate Monitoring: Delving into the most straightforward and evident algorithm for spoofing detection.
• Satellites' CN0 Monitoring: Evaluating CN0’s behavior under coherent and non-coherent attacks.
• Residual Monitoring: Understanding what residuals are and how they behave under various attack scenarios.
• DataStream Authentication.
• Spectrum Monitoring: Employing spectrum analysis as a means to detect GNSS interference.
• Problem of GNSS receivers hang-up due to spoofing. Inability to restore tracking of real signals.
• GPSPATRON solution for GNSS anomaly detection and classification.
