Heathrow and Gatwick airports buy anti-drone systems after scare
London's airports don't want a repeat of the drone panic that left Gatwick travelers grounded for days, and they're willing to spend loads of cash to keep their skies safe. Heathrow and Gatwick have spent millions of pounds on "military-grade" anti-drone systems in the wake of the scare. It's not clear what they've purchased, but it might be a Rafael Drone Dome system that can jam drone communications. The company told the Times that it had seen interest from UK customers, but it's not clear if that included the two airports.
Hackers transform a smartphone gyroscope into an always-on microphone
Apps that use your smartphone's microphone need to ask permission, but the motion sensors? No say-so needed. That might not sound like a big deal, but security researchers from Stanford University and defense firm Rafael have discovered a way to turn Android phone gyroscopes into crude microphones. They call their app "Gyrophone" and here's how it works: the tiny gyros in your phone that measure orientation do so using vibrating pressure plates. As it turns out, they can also pick up air vibrations from sounds, and many Android devices can do it in the 80 to 250 hertz range -- exactly the frequency of a human voice.
US Navy tests first 11-meter missile-firing sea drone (video)
Advances in unmanned military tools and vehicles have come on leaps and bounds, but, until now, we haven't seen a weapon firing drone operating in the seas. A recent test taking part offshore near Maryland saw several missiles launched from a new remote-controlled inflatable-hulled ship. While the Navy has used drones before for mine clearing and other defensive tasks, the small boat (similar to that pictured above) is the first experiment to involve true offensive capabilities. The almost zodiac-like craft has been an ongoing project over recent years, and contains a fully automated system which the Navy calls a "Precision Engagement Module" which uses an Mk-49 mounting with a dual missile launcher manufactured by Rafael. The hope is that such vehicles could patrol the coastline, or serve as a first defense against pirates, and other such small, fast-moving seafaring dangers. If you want to catch it in action, head past the break for the video, but don't be fooled. While it might look like a series of misses, the Navy claims this is just a trick of the camera angle, with all six missiles apparently making contact.
