More on GPS Jamming in the Strait of Hormuz

BBC News on GPS jamming in the conflict between the U.S., Israel and Iran:

The interference currently affecting ships in and around the Strait of Hormuz is far from the first time that [maritime intelligence analyst Michelle Wise] Bockmann has observed GPS jamming impacting vessels’ Automatic Identification Systems (AIS).

The same thing happened in this region last year during the 12-day war between Israel and Iran, and electronic interference has also troubled vessel navigators in the Baltic Sea. But, she says, “This is next-level.”

GPS Jamming and the Iran War

GPS jamming has become pretty much endemic in every conflict, open, hybrid or frozen, so it’s no surprise that it’s going on in the Persian Gulf: “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.” The CNN article goes on to explain why GPS (and other GNSS systems) are so vulnerable, and how spoofing and jamming have become so commonplace.

Deep Learning Applied to Satellite Imagery Reveals Untracked Ships

Speaking of AI-assisted global monitoring: researchers affiliated with Global Fishing Watch have revealed that the global fishing, transport and energy fleets are a lot bigger than expected. They were able to compare the locations of ships carrying AIS transponders with satellite imagery, to which deep learning was applied to classify ships. They conclude that something like three-quarters of industrial fishing vessels, and thirty percent of transport and energy vessels, go untracked. This isn’t necessarily so much about clandestine activity—in many regions ships, especially fishing boats, simply aren’t required to be tracked—but it can, among other things, reveal illegal fishing in protected areas. Results of the study were published in Nature last month. Global Fishing Watch also has an interactive map. [The Verge]

Ships Are Increasingly Spoofing Their Location

Ships spoofing their location is an increasing problem, Anatoly Kurmanaev reports for the New York Times. All large ships are required to carry an AIS transponder that transmits the ship’s ID and position, but some ships are starting to find a way around that.

[O]ver the past year, Windward, a large maritime data company that provides research to the United Nations, has uncovered more than 500 cases of ships manipulating their satellite navigation systems to hide their locations. The vessels carry out the deception by adopting a technology that until recently was confined to the world’s most advanced navies. The technology, in essence, replicates the effect of a VPN cellphone app, making a ship appear to be in one place, while physically being elsewhere.

Its use has included Chinese fishing fleets hiding operations in protected waters off South America, tankers concealing stops in Iranian oil ports, and container ships obfuscating journeys in the Middle East. A U.S. intelligence official, who discussed confidential government assessments on the condition of anonymity, said the deception tactic had already been used for weapons and drug smuggling.

We’ve seen examples of this before, but this is starting to look like an endemic problem.

The Washington Post has six maps of U.S. flights, shipping lanes, electrical transmission lines, railroads and pipelines that highlight “the massive scope of America’s infrastructure” that will presumably be the focus of future Trump administration spending. [Benjamin Hennig]

A Map of Global Shipping

This interactive map shows the location of every single cargo ship over the course of 2012. Shipping routes (the Straits of Malacca look particularly bottlenecked) and materials shipped are available via the interface, and there’s a nice narrated tutorial explaining how the map works. Thanks to David Krathwohl for the tip. [Digg]
