The application of signal jammer in electronic warfare

Evolution of modern weapons – electronic signal jamming weapons

The integrated design for RF GPS jammer makes the most of commonality across all capabilities, reduces life cycle costs, and provides increased protection against worldwide threats, Navy officials say. It is for the US Marine Corps, Navy, and Air Force, and is under supervision of Naval Sea Systems Command. The current option exercise is for Engineering Support Services for JCREW to introduce new technologies; address diminishing material and depot repairs to keep JCREW systems viable for future production as well as maintain operational readiness for the field. 

Electronic warfare (EW), the use of the electromagnetic spectrum to foil enemy forces and protect friendly ones, is perhaps the most time-sensitive of all the weapons in the military arsenal: a matter of nanoseconds could make the difference between life and death. That’s why latency is so critical to EW processing systems. If a radar-guided missile is heading for your aircraft at Mach 5, the aircraft’s radar jammer had better be quick – quick to take in the signal, manipulate it, and retransmit it to fool the adversary with false targets or misleading data on size, distance, heading, speed. Digital RF memories (DRFMs), the specialized RF jammers that do just that, require receive-response latencies of 20 to 100 nanoseconds. Compared to radars – which transmit pulses and receive echoes – DRFMs – which receive pulses and retransmit the signals modulated with jamming techniques – have much more stringent latency requirements.

An even more effective and now proven EW solution is The Marine Corps’ Marine Air Defense Integrated System (MADIS). Based on Sierra Nevada Corporation’s battle-tested counter-IED technologies, MADIS uses a combination of radar and electro-optical sensors to detect, track and target drones and then fires a powerful electronic jammer to defeat the drone’s flight controls. There are several variants of MADIS either fielded or in development, including a fixed version for bases, a standard system mounted on the Joint Light Tactical Vehicle and even a light MADIS that can be carried on an all-terrain vehicle. It is believed that this was the system, lashed to the deck of the U.S.S. Boxer amphibious warfare vessel, that took down an Iranian drone in July in the Persian Gulf. The Marine Corps plans to enhance MADIS by adding either a killer drone or a laser weapon in the future.

Cell Phone Signal Jammer

American jamming weapons are about to land in electronic warfare

The U.S. military is working on a new generation of signal jamming weapons

The US military is working on the next-generation of cell phone jammer to defeat improvised explosive devices (IEDs) that pose such a grave threat to US forces deployed overseas. The jammers are called Joint Counter Radio-Controlled Improvised Explosive Device (RCIED) Electronic Warfare (JCREW) devices. They are high-power, modular, programmable, multiband radio frequency jammers designed to deny enemy use of selected portions of the radio frequency spectrum. They come in 3 varieties – fixed, mounted, and dismounted.

Jammers and other EW systems can be mounted on virtually any platform, including attack drones. Large systems can reach out to engage UASs at higher altitudes and greater distances. One of the most significant advantages of using electronic warfare against hostile drones is the reduced risk of collateral damage. This is particularly important when protecting urban infrastructure such as airports and government buildings. The use of EW against accessible targets also allows the defender to save long-range, but more expensive, kinetic weapons for use against more critical targets such as manned aircraft or ballistic and cruise missiles.

Northrop Grumman will enter its software-programmable GPS jammer, known as JCREW, into full-rate production external link, after receiving a $57.7 million US Navy contract. If all options are exercised, the total contract value could rise to $505 million, with contract completion scheduled for August 2022. JCREW systems are software-programmable jammers for use against device-triggered IEDs. Northrop Grumman have developed dismounted, mounted and fixed-site variants of the system.

The core of SPEAR-EW’s payload is Leonardo’s advanced, miniaturized Digital Radio Frequency Memory (DRFM) technology, which offers the most advanced and future-proof electronic jamming and deception available on the market today.

Powered by a turbojet engine the SPEAR missile offers over double the range, and a far more flexible operating envelope, when compared to a conventional glide weapon. SPEAR-EW utilizes this long endurance through its capacity to be launched at enhanced stand-off ranges and loiter while carrying out its jamming mission.

Use of jamming devices for law enforcement agencies

Jamming devices to prevent crime

Use of mobile phones by inmates has been a menace that could not be controlled owing to the alleged connivance of some prison staff. Many crimes were believed to have been planned in prisons by gangsters who used mobile phones 4G jammer to communicate the plot to their henchmen outside.

In the phone scam, culprits typically guide elderly people via cell phone to send money to the fraudsters’ temporary bank accounts, pretending to be close kin or acquaintances suddenly in a financial bind.

According to dealers of cell phone signal jammer, universities have now been added to the customer list.

In a bid to block access of students to pornographic websites, the Centre told the Supreme Court on Friday that it is exploring the option of installing jammers in school premises but ruled out the possibility of putting the machines in school buses as suggested earlier.

If permitted, the school will jam cell phone frequencies during class time but not between classes or during lunch. «We believe that there are times during the school day that parents need to have access to students and students need to have access to family members, and doctors and things like that,» said Hook.

Canada had considered allowing blocking in similar situations. But Industry Canada, which regulates the country’s telecommunications, decided against it, saying the devices could infringe on personal freedom and affect public safety by crippling communication with law enforcement and security agencies.

In Mexico, the main clients have been banks looking to stop would-be robbers from communicating with their accomplices and the Mexican government, which is planning to use them at prisons, Haim said.

The capabilities of jamming weapons research

Electronic jamming weapons than live with higher cost performance

Weapons capable of jamming or destroying U.S. military and commercial satellites will reach initial operational capability in the next few years, according to a new intelligence report.

The makers of precision-guided munitions no longer take for granted that simple GPS-guidanc

South Korean government officials report that the jamming operation, which began in late March, has been targeting aircraft navigation equipment. North Korea has reportedly broadcast a jamming signal on 100 occasions. A total of 962 planes have been affected by the jamming, as well as nearly 700 fishing vessels. The jamming has also affected cell phone base stations.

For example, trackable interference, aka spoofers, likely generate the entire GPS-like constellation and transmit from a common point; thus, these signals generate exogenous constellation-wide delay (i.e., in a bend-pipe versus line-of-sight RF transmission). Other defining characteristics of a malicious interference may include increased energy (i.e., signal jammer), clock drift/offset coloring, inter-satellite interference, etc.

All four satellite navigation systems, the signals of which the Pole-21 must combat, use closely spaced frequencies, which end up in the interval from 1176.45 to 1575.42 MHz. The fact that even a transmitter with an output of a total of 20 watts in order to jam the radio signals in this range in a radius of 80 kilometers attests to the latest Russian system’s capabilities to create an impenetrable jamming dome

The army used commercial, demand more and more big interference equipment

A lot of public places, commercial and corporate buildings, organizations, colleges and schools, institutions, use portable cell phone blocker. In addition to these places, there are government offices, conference halls, and military cantonment areas, confidential meeting rooms which implement a portable cell phone jammer so as to prevent the disclosure of any private detail or information. There is a lot of information which needs to be kept private and if it leaks through any medium, the results can be very hazardous to the entire organization which definitely no one would like to face.

Privacy of an individual is their own responsibility. No one else would do that for you, you’ll have to make sure that you are secured from the actions of cyber miscreants and take all the necessary steps which are needed to. Best part about a portable mobile phone blocker is that these can be easily taken and installed in almost all kinds of areas.

Whilst evading such jamming is easily possible and having an autopilot likewise, are they currently built into the available drones in a way that can not be overridden by a jamming system who’s manufacture has shall we say a not publicly known arrangement with the drone manufacturer?

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.

From communications jamming to military jamming

The evolution of the jammer

Throughout the corrections world the news spread fast. For South Carolina Corrections director Brian Stirling, the news affirmed his beliefs: to stop the flood of mobile phones streaming into prisons, jamming technology was the best, cheapest, and most efficient way to go.

cell phone jammer can be a small, inexpensive box that transmits a continuous tone to antennas, effectively stopping any cell phone from making or receiving calls.

The Shtora is an electro-optical jammer designed to disrupt guided missiles. It’s not clear if the jammers were switched on, or didn’t work, when the Hawks Mountain Brigade opened fire. Russian media has also reported that the particular tank was an earlier version of the T-90, so more recent upgrades, such as the T-90A which boasts a modified turret, should fare better.

The navy plans to field the Next Generation GPS jammer in evolutionary phases, each focused on a different frequency band. Increment 1, an estimated $8.7 billion acquisition led by Raytheon, will have mid-band capability and will be outfitted on the EA-18G Growler aircraft as soon as 2022 – a recently disclosed one-year delay. Increment 2 is the low-band effort and Increment 3 will focus high-band frequencies; both will also fly on the EA-18G.

Application of uav jammer

Anti-drone jammer Becoming Standard Equipment For Law Enforcement A new line of defense is needed as off-the-shelf home-use drones are being adapted for use as lethal explosive droppng devices by both domestic malcontents and foreign terrorist organizations. What is a drone and how do drones work is answered here in this easy to understand article. Easy to make, cheap to buy, simple to fly, and hard to detect, commercially available drones are one of the most quickly evolving technological threats to military and civilian interests.

DCAA aims to gun down unauthorized drones silently and safely using the all new state of the art Anti Drone Rifle with Signal Jamming Technology. Boise-based anti-drone tech company Black Sage will demonstrate its counter-unmanned aerial vehicle defense system on the State Capitol in Boise, Idaho next week. There are numerous systems built to take down wayward or dangerous drones, but they tend to have one big catch: you need to be relatively close to the drone, wh Engadget LoginThrough the radio, you will be able to integrate your anti drone detection system to C2 systems such as ATAK or similar.

The US Federal Aviation Authority last month issued a warning to US aircraft flying over the eastern Mediterranean region of the increased threat of Russian electronic warfare jamming: “be aware of possible loss of GNSS (global navigation satellite system) signal within Beirut FIR (flight information region) due to unforeseen reasons”

In a war, most of us would have far more serious concerns than calculating a car trip, yet GPS jamming poses a significant threat in its own right.In a war, most of us would have far more serious concerns than calculating a car trip, yet GPS jamming poses a significant threat in its own right. Disruptions of daily life are a crucial part of hybrid warfare (sometimes also called grey-zone warfare or threshold warfare). By causing society to grind to a halt, or even just making daily services such as food, medicine or fuel supply, sewage, news media, or the internet function poorly, an adversary can dramatically weaken the target country without moving a single soldier. In recent years the Kremlin has been refining such practices.

GPS jammers protect military secrets

GPS jammers are used for civilian and military applications

GPS Jammer is designed for area and assets protection against satellite navigated threats like GPS guided missiles. The SCL-APSNT can also be used against low flying UAVs to prevent reconnaissance of important place. GPS portable jammer can be effectively used in combat situations for eliminating satellite navigated guided weapon systems, missiles and ground/airborne threats It is designed to operate on all satellite navigation system available today or in the near future including GPS, GPS II, GALILEO and GLONASS at different power levels. It is upgradable to operate on COMPASS. (SCL-APSNT) provides protection ranges from 30 Km to 150 Km depending on the power output of the jammer and the envisaged region of coverage.

GPS signals make use of a definite and specific frequency. GPS works at two main frequencies. The one is intended for non-military or public use at 1575.42 MHz and the other one is meant for military purpose at 1227.6 MHz. Actually, GPS is based on radio waves.

Overall, using the GPS can be very useful, such as car navigation, finding missing persons and navigating in the sea. Even so, there are many different ways to misuse the GPS, and that is why we have the GPS jammers.

For a radio jammer to work, it needs to be fairly close to the signal its crew wants to disrupt. The Avtobaza, for one, can detect targets up to 93 miles away, according to Air Power Australia, an independent think tank specializing in military electronic systems. Jamming requires more power than detecting does, so the range at which the Avtobaza can disrupt a drone is certainly shorter than 90 miles.

That’s why Russia’s 4G jammer, and the new counter-drone «special forces» that operate them, don’t necessarily pose an existential risk to the US military’s UAVs. The Russian drone-hunters could struggle to pinpoint targets. «It would seem to be hard to do unless you knew where they were going to be and when,» one former US drone-developer explained on condition of anonymity.

Air Force Col. John Dorrian, a spokesman for Combined Joint Task Force-Operation Inherent Resolve, would only describe the devices given to the Iraqis as «jammers.» Dorrian has previously said that U.S forces advising and training the Iraqis have their own jammers to counter drones.

Richard Langley, a professor of geodesy at the University of New Brunswick in Canada, said the jammers would also have a hard time interfering with an encrypted military GPS code broadcast at a frequency of 1227.6 MHz. But the jammers could interfere with signals broadcast at 1575.42 MHz, a band used by commercial GPS receivers. Such receivers could have been bought by individual troops, but the Army tried to derail that practice in January.

Countries compete in jammer technologies

Advantages of the new jamming system

The Mi-8MTPI has the Ikebana jamming system, which is a stand-off portable jammer intended to disrupt an opponent’s battlefield radars, including air search and fire control types associated with air defense systems. This variant has its antennas more centrally located on either side of the helicopter, making it easy to differentiate it from the MTPB version.

The MTPI also has the ability to detect and determine the general location and type of hostile emitters, giving it a limited capacity to conduct intelligence gathering missions on enemy defenses. When the Soviet Union introduced the type in the latter half of the Cold War, part of the goal was to provide more of a multi-mission capability over existing Mi-8/Mi-17-based jammers.

You could probably make a timer somehow that gets activated by being jammed, so if you know the average range of such a GPS signal jammer and the average speed of a vehicle holding a jammer, you could set it to roughly explode underneath if you put it on a road… but I don’t really see it working.

The new trend of electronic warfare

One of the standout improvements is the Gripen E’s electronic warfare (EW) system, which takes advantage of the aircraft’s fully-digital architecture. This and the more powerful jammer-emitter capability, which is made possible by the integrated set of jamming transmitters, radar warning receivers, and the Selex AESA radar set, make for a more powerful EW profile.

“The configuration of the EW system for the Gripen E allows you to focus the jamming signal in a narrower band, so the signal itself is stronger and directed at an individual specific threat,” said one of the Gripen test pilots. The previous EW system produced a broader frequency band signal, which was designed to counter several threats at once.

Officers that don’t trust their leadership can and will issue some fukd orders. As an Army Specialist in Afghanistan, and on mission, I was commanded by my CO to disarm our convoys radio drone gun jammer so a local could make a phone call.

Not military at all, but: Sounds like it would be complete guesswork and only marginally better than just putting it on a timer. Jammers have more range than your average IED. It would just explode as soon as a jammer gets remotely close, and not be harmful at all.

Once the system has a lock on the drone, a radio frequency jammer is then used to overload the drone with signals – knocking out the commands from the unknown owner.

The navy will has a new jamming weapon

The navy is preparing to build next-generation GPS signal jammer weapons

Electronic warfare has come a long way since Pentagon legend Paul Kaminski warned that “years of neglect” had left the US dangerously behind Russia and China. But has the Defense Department made the $2.3 billion a year increases in EW spending that Kaminski and the respected Defense Science Board said was necessary back at the 2014 Association of Old Crows conference, months after Russian jammers fried the Ukrainian army’s communications?

The Naval Air Systems Command (NAVAIR) awarded Northrop Grumman a $35 million, 20-month contract Oct. 25 to demonstrate existing jammer capability for the NJG-LB program. Northrop Grumman is the airborne electronic attack integrator for the Navy’s current EA-18G Growler electronic warfare (EW) system.

The NGJ system will augment, and ultimately replace the EA-18G Growler aircraft’s legacy ALQ-99 tactical mobile phone jammer system with advanced airborne electronic attack capabilities for defeating increasingly advanced and capable threats. Developed in three frequency-focused increments – high-, mid- and low-band – NGJ will bring a significant increase in airborne electronic attack capability to counter complex air defense and communications systems.

Russia’s new strategy for electronic jamming

Russian GPS signal jammer weapons

According to a Russian satellite network reported on July 9th, a Russian Defense Industry Complex said that Russia is making new jamming machines that can scrap military satellites.

He said: «at present, the construction of jammers is being carried out, which will replace the» -22PP «woodcutter» aircraft «serving in the air force. The new jammer will have new equipment to carry out electronic interference suppression for any target in sea, land, land and air, and to scrap the enemy’s satellite for ensuring ground navigation and radio communication. »

Perhaps sensing the hard road ahead for jammers, the NSW government has previously flagged the possible use of jamming technologies to stop inmates from using mobile phones.

Comms Alliance and AMTA also said that any arrangements that are put in place for jammers beyond 2018 will need to have in-built review mechanisms so the impact of the technology on future 5G operations can be reviewed. Copyright © iTnews.

Drone jammer gun

Russia has experimented with electronic signal blocker in the United States

The Russians began jamming some smaller U.S. drones several weeks ago, the officials said, after a series of suspected chemical weapons attacks on civilians in rebel-held eastern Ghouta. The Russian military was concerned the U.S. military would retaliate for the attacks and began jamming the GPS systems of drones operating in the area, the officials explained.

U.S. analysts first caught the Russian military drone jammer drones in eastern Ukraine four years ago, after the invasion of Crimea, according to Humphreys. He said the jammers were initially detected as faint signals from space, bouncing off the earth’s surface. The jammers «had a pretty significant impact» on the United Nations surveillance drones that were attempting to monitor the area, grounding the fleet for days and halting intelligence gathering from the air.

While jamming isn’t anywhere near shooting, the provocative activity «could lead to an escalatory pattern that could be negative for both sides,» and the US will «not look kindly» on the practice, according to an expert.

US officials told the Wall Street Journal early in April that intelligence officers detected China moving radar and communications jamming equipment to the South China Sea.

Electronic military jammer provocation from China

The US Navy’s USS Theodore Roosevelt aircraft carrier has reached the Philippines, and it looks like China has jamming equipment in the South China Sea. While wifi jammer isn’t anywhere near shooting, the provocative activity «could lead to an escalatory pattern that could be negative for both sides,» and the US will «not look kindly» on the practice, according to an expert.

The telecommunications industry has long opposed jamming cell signals, saying that could interfere with legal cell users nearby. But several companies, including Verizon, A&T, Sprint and T-Mobile, agreed to join in tests of various platforms that can jam all calls or simply unauthorized ones, Stirling said.

But while manned aircraft can usually fight back against signal jamming, and pilots in a cockpit can always use their own judgment if communications or navigation is lost, jamming could pose a serious threat to the US Navy’s drones, as there’s no one in the cockpit, according to Lamrani.

China’s military cell phone jammer equipment affects U.S. drone flights

If China is jamming US Navy aircraft flying in international airspace at sea, it serve as yet another sign that Beijing may disregard international law and norms to defend its South China Sea land grab.

An advocate for cell phone jammers being installed in South Carolina prisons, Stirling has previously said that prisoner access to cell phones is no different than access to weapons. McMaster has also supported cell phone jamming in prisons.

In Monday’s press conference, McMaster said Stirling has led the battle for the whole country regarding prison signal jamming. «I know prisons all around this country that would be safer… if this jamming were allowed,» the governor said.

Known as one of the most effective jammers in the world, the Russian helicopter-based radio electronic warfare system Rychag-AV is capable of protecting the entire vehicle by «blinding» all enemy warplanes and missiles within several hundred kilometers.
