New Navigation Tech Shields Ships from GPS Interference

A new satellite-based navigation system developed shields ships from rising GPS interference threats like jamming, spoofing and hacking.

Tschudi Shipping Company, NAL Research, and SGM Technology AS have collaborated to create a new navigation and tracking solution that operates even when satellite signals are interrupted. The system uses the  Iridium low-Earth Orbit (LEO) satellite network to provide and ensure global coverage and enhanced reliability.

The collaboration addresses the growing problem of Global Positioning System (GPS) and Global Navigation Satellite System (GNSS) interference, such as jamming and spoofing, affecting the maritime industry worldwide. Most recently, maritime GPS and GNSS disruptions have hit record levels. According to marine insurer NorthStandard, there has been a 350% increase in reported cases where spoofing and jamming have affected vessels. These incidents cause serious safety risks, delays, and financial losses, among other many issues.

“Protection against GPS vulnerabilities is no longer a nice-to-have, but a necessity to ensure operational success and asset safety,” said Robert Bills, President of NAL Research. “Through this collaborative effort, we are aiming to achieve complete global situational awareness and increase safety at sea for our commercial maritime customers, even in the most remote and challenging situations.”

NAL brings its expertise in Assured Positioning, Navigation, and Timing (APNT), tracking, and connectivity to help develop solutions powered by the Iridium® PNT service. SGM contributes over 15 years of experience in delivering maritime technology expertise, while Tschudi Shipping Company adds its long history in global shipping and logistics.

Iridium’s low-Earth orbit satellite network powers the system. It provides global coverage and ensure reliable asset tracking and assured navigation, even in areas where jamming, spoofing, or other GPS/GNSS interference disrupt operations. It is currently in trials with select shipowners to ensure it performs reliably in real-world conditions. 

“In today’s maritime landscape, the threat of GPS jamming and spoofing is no longer theoretical – it’s a growing reality. Ensuring navigational safety is critical, not just for protecting cargo and vessels, but for safeguarding the lives of seafarers who rely on precise and trustworthy systems every day,” said Steffen Grefsgård, CEO of SGM Technology.

Felix Tschudi, Chairman of the Tschudi Group, said the industry needs to act together to protect maritime operations. “As a fifth-generation shipping company, we’ve witnessed the evolution of maritime navigation, but never before have we faced technological threats like GPS jamming and spoofing,” he said. “These disruptions pose a serious risk to vessel safety, crew welfare, and the reliability of global trade routes. The industry must act collectively to address these vulnerabilities to protect maritime personnel and assets.”
