Russia's jamming electronic weapons program

Electronic warfare has become a trend, and GPS signal jammer weapon is key


It is well known that Russia's military strength is leading in the world. In order to maintain that lead, Russia has invested a lot of capital in the field of electronic warfare. Of course, as one of Russia's rival, the United States is not far behind.


Militaries the world over regularly practice ‘electronic warfare’, which involves the jamming of everything from radio communications and radar through to satellite signals. But, as with all ‘live fire’ exercises, threat warnings are issued and exclusion spaces declared.


Silok is the latest in a long line of radio-frequency-portable jammer systems that the Russian military has deployed since the Cold War in order to block enemy communications, including the radio links that allow the operators to control drones — and drones to send back video and other intelligence data.


While the Russian army, and the Soviet army before it, long has operated R.F.-jammers, it wasn’t until October 2017 that the Kremlin stood up its first ground-based unit specializing in defeating enemy drones.


The Russians also deployed R.F.-jammers to Syria to protect Moscow’s installations in that country. The new Silok jammer joined the Russian force in Syria in August 2018.



The development of American wifi jammer weapons


US and Norwegian forces regularly use airfields in northern Norway and Finland. In this instance, the jamming was believed to have been coming out of Russian territory as it was engaged in its controversial Zapad 2017 military exercise.


Russia has developed jamming equipment that can distort GPS signals over a wide area. Its R330Zh jammer reportedly disrupted flights some 250km on the Norwegian side of the border with Russia. But its troops are also equipped with handheld GPS signal jammer for sale that can affect receivers out to an 80km radius.


But even with precision electronic warfare, jamming from one place for a long time is generally an invitation for enemy fire, so EW systems need to be mobile. (Even then friendly forces generally don’t hang out too close when enemy artillery is in range). That brings us to the TV part of EWTV, the Tactical Vehicle.


The Pentagon is keenly aware of the risk. The Defense Advanced Research Projects Agency's (DARPA) long-running Communications Under Extreme R.F. Spectrum Conditions initiative and similar programs aim to develop "signal detection and reasoning technology that allows radios to recognize interference and jamming, and adapt to maintain communications — even in the presence of severe and/or adaptive jamming," according to DARPA program manager Joseph Evans.

Poortable Jammers are everywhere

Portable jammer are getting more and more attention in the military field


Perfectjammer has announced the launch of DroneCannon RW, a counterdrone jammer which is designed for use on remote weapon stations.


It said during radio jamming, a loud noise is transmitted over stations so that listeners can’t hear the content. South Korean officials have previously said that North Korea used radio waves to wifi jammer systems, affecting planes and ships.


US department of Homeland Security (DHS) operates autonomous drones patrolling over the USA-Mexico border, which suffer jamming attacks by border smugglers, mainly the drug cartels," said Gai Mar-Chaim, Senior Partner at the management consulting firm POC. "The DHS gives high priority for lightweight anti-jamming solutions for this challenge, and GPSdome is the only commercially available solution that weighs less than 150 gram and consumes power less than 0.75 Watt.


The BBC broadcasts are carried on shortwave frequencies from Taiwan and Uzbekistan, and on medium wave from Mongolia, 38 North reported. It said it wasn’t possible to determine if the medium wave frequency was also targeted by jamming.


Also unique is that North Korea’s jamming is high power, sustained and from fixed locations – so it’s easy to identify where it’s coming from and the impacts. How much more difficult is it when signal jammer for sale are low power and are in a vehicle that quickly passes by? It took many months, and a concerted effort by several agencies, to locate the signal intermittently jamming an aircraft landing system at the Newark (EWR) airport in the United States. And who is to say if a dropped cell call or a glitch in an IT network is due to a jammer passing by or something else?



The use of wifi jammer in multiple domains


Jamming GPS and other satellite navigation systems is the classic asymmetric threat. It’s inexpensive, equipment is readily available and easy to use, and its effects are scalable from targeted local impacts to wide area strategic disruptions. At the same time it is very, very difficult to detect, especially when operated intermittently and/or from a moving platform, and its impacts are often attributed to other causes.


Prison cell phone 5G jammer have become a necessary addition to the arsenal of tools1 required for the safekeeping of inmates. Cell phones are becoming smaller every day, making them easier for inmates smuggle into facilities. This creates an even more difficult job for the already burdened correctional worker, however a cell phone jammer is the answer to restricting the inmates from using the cell phones for potentially dangerous activities. Cell phone jammer use can also force inmates to use prison approved / monitored phone lines.


Such tests could lead to the broader use of technologies like jamming inside prisons to immobilize inmate phones, which officials across the country have described as their No. 1 security threat.
