It doesn’t appear that the drone was hit by a projectile or laser in its descent (though evidence of such would certainly change this analysis). Barring a physical projectile, the known non-kinetic methods for stopping a drone are threefold: radio frequency (RF) jamming, global navigation satellite system (GNSS) jamming, and spoofing. With RF jamming, the link between the drone and its operator is severed, usually causing the drone to descend or return to home. With GNSS, the drone’s link to satellite navigation is lost, and the drone then usually hovers in place, lands, or returns home. With spoofing, the attacker feeds the drone new information to take control of its flight.
The high power drone jammer can help your to jam all cell phoner signal: 2G, 3G, 4G. In addition your can also blocker with GPS, WiFi. This jammer has power adjustablefunction, your can adjustable the jam range base on.
The U.S. Army wants drone-mounted jammer now to dominate future electronic warfare and is switching to a little-understood and lightly regulated contracting method to get them. GPS jammers are usually small devices that plug into a vehicle’s lighter port and emit radio signals that overpower or drown out much weaker signals such as GPS or others.
Today will introduce is the best-selling products in Perfectjammer – Power Adjustable 8 Bands Cell Phone Signal WiFi GPS jammer. Why is this product the most popular product? Look at the following description:
In timing applications, jammers can disrupt the GPS signal, causing the underlying systems to lose their ability to synchronize their internal clocks and, in turn, their ability to stay in sync with the rest of the network. Since many critical infrastructures sectors require synchronization across their network to be within millionths of a second, even short-term GPS outages can have a major impact. Worse, when an outage occurs, there’s typically nothing to indicate that it’s a result of jamming. The GPS signal simply is not received anymore.
