Blog Editor’s Note: Late last year Durk Van Willigen gave a presentation at the Royal Institute of Navigation’s International Navigation Conference at Bristol. In addition to providing his insights on resilience, the presentation included these images of a really, really small jammer.

It’s about a inch cube or 25 mm X 25 mm X 25 mm. Bigger than a standard die, but not much bigger than a US 25 cent coin. And that includes the antenna and battery!

Durk reports that this device has been around since at least the year 2000, and the Dutch Police have found it to be effective up to 100m.

Has anyone out there found a smaller jammer? If so, send us a photo: [email protected]
