“This new smart rifle puts too much power into the civilian world,” he says. Smart weapons analyst Noel Sharkey at the University of Sheffield in the UK is concerned. And some hunters claim it removes the “fair chase” element that they say makes hunting a sport. De-skilling snipingīut some US military veterans say a device that, in essence, de-skills sharpshooting should not be on sale to civilians. In tests, the system has proven astonishingly accurate – even with novices – at hitting targets at a range of 500 to 900 metres.
In addition, it lets the user key a PIN into a smartphone to activate the guided aiming. This allows imagery from the sight to be streamed to a smartphone or tablet, so the user can share what they are seeing with others. The gun is novel at another level: it has Wi-Fi. At the same time, the algorithm increases the pressure required to pull the trigger, only reducing it when the gun’s crosshairs are right over the laser dot – and the bullet is then fired. The computer then runs an algorithm using image-processing routines to keep track of the target as it moves, keeping the laser dot “painted” on the same point. The user simply takes aim and presses a button near the trigger when a dot from the laser illuminates the target. To do this, the PGF’s tracking system includes a computer running the open-source Linux operating system, a laser rangefinder, a camera and a high-resolution colour display in an integrated sighting scope mounted on top of the weapon.
The PGF lets the user choose a target in the rifle’s sights while the weapon decides when it is the best time to shoot – compensating for factors like wind speed, arm shake, recoil, air temperature, humidity and the bullet’s drop due to gravity, all of which can affect accuracy.
