Virginia-based NAL Research has partnered with Norway’s Tschudi Shipping and SGM Technology to develop an advanced maritime navigation solution designed to keep vessels operational and secure in GPS-denied or spoofed environments. The new system, called PntGuard, aims to enhance situational awareness and navigational resilience for ships operating in high-risk electronic warfare zones.
The PntGuard system is a plug-and-play navigational support solution that provides real-time alerts when a ship’s GPS position has been compromised. It allows maritime crews to immediately detect spoofing or interference, enabling them to respond quickly to maintain accurate navigation and safety at sea.
At its core, PntGuard consists of two integrated components — a receiver unit that links directly to a Positioning, Navigation, and Timing (PNT) service, and a bridge display interface. The display shows both the spoofed GPS coordinates and the vessel’s true, verified location, helping operators distinguish between false and authentic positional data instantly.
The collaboration highlights a growing industry push toward GPS-independent navigation systems, as maritime and defense sectors face increased electronic interference and cyber threats. By combining NAL Research’s satellite communication expertise with Norwegian maritime innovation, PntGuard positions itself as a key enabler for safer and more reliable global maritime operations.
