Ships hide their locations with fake GPS data

Like all (?) aircraft, ships must have transponders that broadcast their position. The information is public and can be viewed on websites such as AIS Marine Traffic.

However, according to a analysis published in the New York Times, a shipping data company called Windward "uncovered more than 500 cases of ships tampering with their satellite navigation systems to hide their locations."ship antenna

The article, by Anatoly Kurmanaev, mentions the Cypriot tanker Reliant, which was seen taking oil from a Venezuelan refinery last December. However, at the same time, the ship reported its position at a distance of about 300 nautical miles (about 500 kilometers), "off the coast of St. Lucia."

It's illegal (under international law), but the fast-growing practice allows ships to circumvent international laws and sanctions, the Times reports, and it "could change the way goods are moved around the world, with implications for international law enforcement, organized crime and global trade".

These practices are used by Chinese fishing fleets that hide in protected waters off South America, tankers that hide their stops at Iranian oil ports, and container ships that hide their journeys in the Middle East. A US intelligence official, who cited confidential government estimates on condition of anonymity, said the deception tactic has already been used to smuggle weapons and drugs.

"It's a new way for ships to convey a completely different identity," said Matan Peled, founder of Windward.

"Things have unfolded with astonishing and terrifying speed. . . ."

The spread of AIS manipulation shows how easy it is to subvert the technology — the Global Positioning System, or GPS — that's used almost everywhere, said Dana Goward, a former senior U.S. Coast Guard official and president of the Resilient Navigation and Timing Foundation. of a Virginia-based GPS policy group. "This shows how vulnerable the system is," he said.
