A directional jamming attack can destroy enemy communication systems

But it’s a completely non-discriminatory attack, it will try to knock out every WiFi network it sees. It may however be advantageous to try and jam one specific access point, or perhaps even just one client device. In other cases the broad radius attack may fail, and a more direct approach is required. For those situations, signal jammer has a number of options to tailor the attack to the situation at hand.

This has been a high-level demonstration of jamming a target and applying electronic warfare techniques to hacking. Stay tuned for more!This GPS jammer is so tiny you can fit into pocket and carry it anywhere. It can be powered through your power bank or 3.7v LiPo battery. You can select which WiFi network you want to jam and attack on it. But be sure this is just for educational purposes; do not use this for the wrong purposes.

Most GPS receivers will have a certain amount of automatic gain control (AGC), which is a feedback loop designed to keep power levels constant. Many GPS receivers, though, simply aren’t designed with enough AGC to handle pseudolite-level signals (think GPS jammers again).

Pursuit drone and jamming technology offers affordable counter-drone capability. Saskatoon, SK & Portland, OR – May 8, 2017 – Portland, Oregon-based Radio Hill Technologies (RHT) has teamed up with Canadian drone manufacturer, Saskatoon-based Draganfly Innovations Inc. to explore an emerging counter-drone technology. Radio Hill, inventor of the Dronebuster, a 5 lb., 21-inch long, handheld counter-drone detection and jamming system, recently completed a large sale of Block 3 Dronebusters for the United States Army.

In our quest to augment GPS and make it more robust, we have in fact created a GPS jammer, and achieved exactly the opposite. As with any radio communications link, the received power is extremely sensitive to the distance (varying with the square of distance). In pseudolite terminology, this is known as the near/far problem.

The objective of a tender issued in December of last year, with a closing date of Feb. 17, is to “develop a ground-based GNSS Jammer Location capability utilizing a single GNSS receiver capable of estimating the position of a GNSS jammer within 100 meters, and estimating jammer position within 10 meters when networked with other sensors.”
