When it comes to technology and tanks, we often think of one of two extremes. Firstly the original tanks from years ago, with the large cannons mounted to tracks and then we think to our idea of the future, with giant floating armoured platforms. It would seem the marines are looking to go somewhere inbetween, but not with flying tanks but ones equipped with more systems to help protect tanks from their enemies.
The U.S. Marine Corps is looking at using technology, not additional armour, to help protect their vehicles. First up on the list of technologies is the use of electronic anti-missile systems, or active protective systems, that will detect and intercept anything from a guided anti-tank rocket to the likes of a rocket propelled grenade (such as those used in RPG’s). The system in place would be the Israli Trophy Active Protection System (APS), with four systems being mounted to both Stryker combat vehicles and M1A2 tanks.
With jammers and missile interception components working together the hardware is commonly designed to protect ships or airplanes, but with threats changing the military wants to be one step ahead. That isn’t all, with the Marines also looking at “unmanned aerial systems” (Drones) to help spot enemies before they can even launch the attack.
Combining knowledge about threats before they happen with active and passive defence systems is a nice way to protect soldiers from unwanted threats at a moments notice.
We use our mobile phones for everything these days, from playing your latest game or reading your latest to talking about the last few days to your friends. Sometimes you just want to escape this, as a man from Chicago wanted when he started blocking cell phones on his daily subway trip.
Undercover officers arrested a 63-year-old man, who according to his lawyers just wanted to have a little quiet on his commute. The device he used to get that quiet was apparently imported from China, being used to block signals going to and from cell phones in his train car.
Dennis Nicholl’s lawyer stated that “he’s disturbed by people talking around him”. While this may be the case, people have been fined up to $48, 000 for using cell phone jammers, something that apparently Nicholl’s was doing for a while now.
The police were apparently told months ago and had even managed to obtain his photo, the end result being the undercover police. With a picture of Nicholl’s using the device on the subway, it was only a matter of time before they acted on the information. The charge Nicholl’s now faces is “unlawful interference with a public utility”, something he was also charged with back in 2009 for the same action.
Researchers at the Korea Advanced Institute of Science and Technology (KAIST) in Daejon, South Korea, seem to have found an easy way to take out drones from the sky using ‘the right sound’. They explained that some components inside drones are vulnerable to certain frequencies, so with the right one, you can disable them.
One of the researchers stated that components such as gyroscopes have been made to resonate with sound above the audible spectrum, but some of them are still in the audible spectrum, which makes them vulnerable to interference. In an experiment, they used a speaker attached to a drone and connected to a laptop via Wi-Fi. When the right sound was played through the speaker, the drone dived down and crashed.
Of course, you won’t be able to physically attach a speaker to a drone in most cases if you want to make it crash, but this proves that sounds can be used to crash drones. Other experiments involved attaching a speaker to a police shield and making a sonic wall, but without the proper high-tech equipment to keep aim on the drone while it spirals out of control, it is useless.
The conclusion is that drone enthusiasts shouldn’t worry about it, unless your neighbour silently attached a speaker to your drone. Using high-tech sound disruptors, as far as I know, is illegal in most countries, so if you’re not piloting a high-tech military drone, you should be fine.
