    Smartphone App Triangulates Sniper Fire

    "For the last decade, the Department of Defense has spent millions of dollars to develop sophisticated sniper location systems that are installed in military vehicles and require dedicated sensor arrays".

    Now

    "A team of computer engineers from Vanderbilt University's Institute of Software Integrated Systems has made such a scenario possible by developing an inexpensive hardware module and related software that can transform an Android smartphone into a simple shooter location system".

    That should save the army a lot of money.

    Somehow I doubt that a single-point sensor (like a camera) is going to be very exacting with respect to "triangulation," particularly if a shot occurs outside line-of-sight. Somehow I doubt Apple, Samsung, Nokia and others built their phones with sophisticated triangulation in mind. But then, I'm not a sound physicist or sensor designer. Perhaps I'm all wet, on that score.

    The future of sniping is in suppressed weapons. Not enough sound to detect,no location found.In several warring countrys it's already rendered the high dolloar technology obsolete.
    I would rather stand against the cannons of the wicked than against the prayers of the righteous.

    Smartphones are smart!

    Well, not with only one phone but...

    If you install the app in a couple of phones and allow them to exchange timing information, you will have a very quick and reasonably triangulation of the shooters position. And if you are watching "important people" in a planned manner, you can have a mobile or microphonr box higher up, in a building or just on a 3m pole. This will also give you the altitude of the shooter.

    Also,

    This technology can be used to detect helicopters. Let the mobile app look for the low frequency but rather high energy flapping sound of the rotors.

    Equip a couple of troopers with mobiles and the app and they have an increased survival rate.

    I suppose a high-powered laser rifle will make no sound at all. The beam travels a bit faster than a bullet, too. Triangulate that.

    Not to mention those phased plasma rifles in the 40-watt range.
