Final Presentation of NAVISP EL1-064bis “Black-Box for an optimised GNSS spectrum monitoring network using artificial intelligence”

The use of GNSS has become ubiquitous across a wide range of applications, from basic personal navigation devices to critical infrastructure and safety-of-life services, where accuracy, availability, integrity, and continuity of PNT (Positioning, Navigation, and Timing) information are of paramount importance. Huld s.r.o. will present their work during this webinar.

However, due to the low power level of GNSS signals at the Earth's surface, the system is highly vulnerable to Radio-Frequency (RF) interference – whether unintentional or intentional, such as jamming and spoofing attacks.

Although the awareness of GNSS jamming and spoofing impacts is rising significantly in recent years, there is already a huge number of legacy GNSS receivers providing timing and localization outputs deployed across various applications.

Focus of this activity is development of Block-box, an external RF2RF device capable of protecting any COTS GNSS receiver against effects of RF interference in a “plug-n-play” manner and thus covering the technological gap between the legacy PNT devices and possible future more secure solutions in a quick, simple and inexpensive manner.

With the following key capabilities, the Block-box aims to provide a robust and future-ready solution for safeguarding GNSS-reliant applications.

• Local GNSS threats and system anomalies detection and classification based on an on-bard implemented Artificial Intelligence engine,
• GNSS threats mitigation, signal cleaning and retransmission at Radio Frequency to support real-time protection for a variety of applications at the user level,
• Cloud data processing and sharing, enabling design and fine tuning of the AI/ML algorithms and allowing for GNSS threats and system anomalies detection and classification on a regional scale when multiple Block-box unit are deployed at different sites.

As part of this project, Huld s.r.o. developed a TRL 4 prototype of Block-box providing:

• Real-time jamming detection, classification and mitigation simultaneously in E1/L1, E5, E6 and L2 bands.
• Real-time spoofing detection and reporting for Galileo E1 and GPS L1 C/A signals.
• Record/replay up to 46 MHz bandwidth.
• Server/cloud control application including AI retraining scripts.
• Offline demonstration of spoofing mitigation for Galileo E1 signal.

A crucial part of the project was the validation and experimentation campaign, which involved testing the system using both synthetic and in-field collected data.
