Final Presentation of NAVISP Project EL2-078 "Galileo Smart Traceability Anti-spoofing (GSTA)" Now Available:

On Wednesday, December 18th, 2024, Origosat Srl (IT), Fondazione LINKS (IT), and INRiM (Istituto Nazionale di Ricerca Metrologica  IT) presented the results of the project: "Galileo Smart Traceability Anti-spoofing (GSTA, NAVISP-EL2-078)." This project addressed the critical challenge of GNSS spoofing and meaconing, which threaten the integrity and security of satellite positioning systems used across multiple sectors.

The GSTA solution integrates a fusion of technologies:  GNSS, ADS-B (Automatic Dependent Surveillance–Broadcast), and network-based timing synchronization to create a robust framework for detecting and mitigating spoofing attacks. The system enhances resilience against both signal retransmission (meaconing) and fake signals (spoofing) in real-time. 

The project achieved significant milestones, including the development and deployment of a GNSS receiver equipped with advanced anti-spoofing capabilities. Extensive field trials were conducted in diverse user scenarios, such as urban and open-field settings, to validate the effectiveness of the solution. These trials demonstrated the receiver's ability to detect and neutralize spoofing attempts while ensuring the accuracy and authenticity of position and timing information.

GSTA also features an enhanced signal processing algorithm designed to provide high resilience against more sophisticated spoofing techniques. The algorithm was extensively validated through field tests, proving its capability to mitigate attacks in various operational environments and ensuring the robustness of the solution in real-world scenarios. These aspects indicate readiness for continued development or deployment in real-world scenarios.

The project highlights NAVISP's commitment to advancing innovative concepts and technologies in the Positioning, Navigation, and Timing (PNT) domain, ensuring that critical applications maintain resilience against emerging threats.

The project was part of NAVISP Element 2, aimed at supporting industrial competitiveness and stimulating innovation in the PNT sector.
