US-based NAL Research has joined hands with Norwegian firms Tschudi Shipping and SGM Technology to create a cutting-edge maritime navigation system capable of operating effectively even when GPS signals are jammed or spoofed. The jointly developed solution, named PntGuard, is engineered to safeguard vessels against location spoofing and positioning errors in contested or degraded navigation environments.
PntGuard operates as a plug-and-play maritime defense tool, offering instant alerts to ship crews whenever the vessel’s GPS-derived position is manipulated. The system enables immediate recognition of navigation anomalies, supporting timely corrective actions to ensure vessel safety and route accuracy.
The solution integrates two primary modules: a receiver that interfaces with a Positioning, Navigation, and Timing (PNT) network, and a bridge display unit. This interface presents both the spoofed GPS signal and the ship’s authentic real-time coordinates, allowing operators to visually verify the vessel’s true position within seconds.
The initiative underscores the growing demand for GPS-resilient maritime technology as global shipping and defense sectors confront evolving electronic warfare and cybersecurity challenges. Leveraging NAL Research’s satellite navigation capabilities alongside Norway’s strong maritime engineering base, the PntGuard system represents a crucial advancement in secure, resilient navigation for modern fleets.
