U.S. company NAL Research has teamed with Norway’s Tschudi Shipping and SGM Technology to introduce PntGuard, a compact anti-spoofing navigation aid built to protect ships from GPS manipulation. Designed as a simple retrofit, the system connects to a secure PNT service and presents a dual-display interface — one tracing the falsified GPS feed, the other showing the vessel’s verified coordinates. When spoofing or jamming occurs, PntGuard instantly alerts crews and recommends corrective maneuvers. The partnership blends NAL’s precision PNT hardware with Norwegian maritime engineering, addressing a critical vulnerability for global trade and naval logistics. Electronic interference incidents have risen sharply in the Baltic and Black Sea regions, where adversaries test jamming capabilities. PntGuard’s advantage lies in its independence from any single satellite source, drawing on hybrid PNT inputs including inertial and terrestrial signals. Its intuitive display integrates easily into existing navigation consoles, minimizing crew training needs. Developers emphasize its role in protecting both commercial fleets and defense auxiliaries operating near high-risk zones. The collaboration aligns with trans-Atlantic efforts to harden navigation systems under the NATO Resilient PNT initiative. Industry observers view PntGuard as a scalable, exportable technology — an affordable safeguard for the shipping sector as electronic warfare increasingly threatens maritime safety.
