PntGuard: Safeguarding Maritime Navigation from GNSS Spoofing

PntGuard™ is a new maritime security solution designed to combat Global Navigation Satellite System (GNSS) spoofing and jamming at sea. Developed through a collaboration between Tschudi Shipping Company, NAL Research, and SGM Technology AS, PntGuard provides vessels with authenticated, true position data even when other bridge systems are compromised by malicious electronic warfare. The source emphasises that the increasing threat of GNSS disruption poses significant risks to maritime safety and compliance, potentially leading to collisions, sanctions violations, and insurance disputes. PntGuard leverages the Iridium® low-Earth orbit (LEO) satellite network to deliver a highly resilient signal, offering a standalone navigational aid that instantly alerts crews to position falsification and provides the vessel’s true track in real-time.

Iridium Unveils PNT ASIC for Global GPS Protection

This new chip is intended to offer comprehensive protection against the rising threat of jamming and spoofing of traditional Global Navigation Satellite Systems (GNSS), such as GPS, which has led to high-profile disruptions and significant economic risk. Measuring just 8mm by 8mm, the ASIC can integrate into a wide array of devices, receiving a secure signal from the Iridium satellite network that is 1,000 times more powerful than GPS. Iridium states that this device will democratise GNSS resilience and serve as a reliable alternative or primary source for PNT data across government, industrial, and consumer applications, with commercial availability planned for mid-2026.
