Military GPS Jamming is Interfering with the Navigation Systems of Commercial Ships

Wait 5 sec.

"Within 24 hours of the first US-Israeli strikes on Iran, ships in the region's waters found their navigation systems had gone haywire," reports CNN, "erroneously indicating that the vessels were at airports, a nuclear power plant and on Iranian land. "The location confusion was a result of widespread jamming and spoofing of signals from global positioning satellite systems."Used by all sides in conflict zones to disrupt the paths of drones and missiles, the process involves militaries and affiliated groups intentionally broadcasting high-intensity radio signals in the same frequency bands used by navigation tools. Jamming results in the disruption of a vehicle's satellite-based positioning while spoofing leads to navigation systems reporting a false location. Though commercial vessels are not the target, the electronic interference disrupted the navigation systems of more than 1,100 commercial ships in UAE, Qatari, Omani and Iranian waters on February 28, according to a report from Windward, a shipping intelligence firm. Jamming and spoofing also slowed marine traffic moving through the Strait of Hormuz, a congested shipping lane that handles roughly 20% of the world's oil and gas exports and where precise navigation is essential, Windward's data showed.... Daily incidents have more than doubled, rising from 350 when the conflict began to 672 by March 2, the firm reported. As use of this warfare tactic grows, experts worry the impacts could reach far beyond battlespaces.... In June 2025, electronic interference with navigation systems was thought to be a factor in the collision between two oil tankers, Adalynn and Front Eagle, off the coast of the UAE... The number of global positioning system signal loss events affecting aircraft increased by 220% between 2021 and 2024, according to data from the International Air Transport Association. Last year, IATA said that the aviation industry must act to stay ahead of the threat. Cockpits are seeing their navigation displays "literally drift away from reality," said a commercial pilot, who didn't want to be identified because he was not permitted to speak publicly. He said that he and his colleagues have experienced map shifts, where the aircraft location appears to move up to 1 mile away from the actual flight path, false altitude information that leads to phantom "pull up" commands, and systems suggesting an aircraft was on a taxiway, a path that connects runways with various airport facilities, when taking off. These incidents force pilots to rely on manual actions that increase workload, often during the most exhausting points of long-haul flights, he said. "Alternative navigational tools that don't rely on GPS, but instead harness quantum technology, are also in development," the article points out, "but remain a long way off operational use."Read more of this story at Slashdot.
