Jamming devices are also often featured in secret agent and movement photographs. Dependent on the scene, heroes or villains would simply flick a activate a device or console to prevent their adversaries from creating a name, activating some other device or triggering a bomb. On different scenes, cell phone jammer are used to interrupt radio and different verbal exchange indicators in addition to rendering radar and different route structures. People might be amazed to realize that the undercover agent devices they see in those flicks are available commercially at the moment.
Simply pushing lots of CW power into the ether is the most inefficient method of jamming and rarely used because of this. More efficient is a tailored jamming system that is modulated in a way that causes problems in the demodulator of the receiver being jammed, usually by using a high peek pulse power at a critical frequency to the receiver demodulation. Even more efficient is to mess with the stages beyond the receiver such as sending valid modulation that mucks up the computer data processing.
The rifle’s jammers can shut down signals at 433MHz, 915MHz, 2.4GHz, and 5.8GHz RF bands simultaneously, ensuring it covers all the most common signal frequencies drones use for communication, with the option to also create GNSS disruption (basically, GPS and GLONASS won’t work correctly). With the signal shut down, any drone in the vicinity will be forced to land on the spot or return back to its starting point, depending on how its internal algorithms are set up, giving folks the ability to retrieve it for investigation (if it lands) or sending back a potential threat (if it returns home). When jammed, the drone’s video transmission is also immediately ceased, so it can no longer transmit any footage to the operator.
GPS denial is a becoming a huge issue for American military planners. Peer states, especially Russia, are already putting GPS spoofing and jamming tactics to work during various training events near their own borders. We have discussed this situation in great depth before, and I would suggest you read this article to understand just how deeply the loss of reliable global positioning system data can mean for the U.S. and its allies during a time of war, as well as what is being done to overcome such a monumental hurdle.
