Although the term may seem intuitive, there are many ways to interfere with radio signals. Generally speaking, jamming is the deliberate blocking or interference of radio signals. For decades, totalitarian regimes such as Russia and China have used wireless signal jammers to jam signals from other countries or transmitters that send messages they don’t like. Signal jamming has a long military history, including jamming communications, jamming drones, and jamming GPS.

If we tune the transmitter (HackRF in this case) to the same frequency and modulation type, and have enough power, we can “drown out” the signal coming into the receiver. Some of the most common types of interference include sending random noise, random pulses, staircase tones, pulses, and sweeps.

The main limitation we have to focus on is signal strength. These only work when we are close to the receiver or can project a very strong signal. In addition, the Russian military signal jammer uses frequency hopping technology, the signal changes frequency at a very fast rate. In this case, we might use multiple transceivers and target multiple frequencies (we don’t need to target all frequencies as the missing components would interfere with the signal sufficiently) or set the transmit bandwidth very wide to cover multiple frequencies.

Signal jamming has a long and storied history in military tactics. Although some military communications are encrypted (many Russian shortwave communications are unencrypted and can be intercepted), that doesn’t stop us from jamming them. Essentially, jamming it prevents the signal from being picked up like a receiver. This could have important military implications.

As the threat of GPS/GNSS electronic warfare becomes more real and significant, military platforms need to be protected from mission failure. With the introduction of GPS/GNSS* military signal jammer, the demand for military jammers is growing in response to the anti-jamming and deception areas.

During military missions, whether fighter jets, helicopters, missiles, surface ships or armored vehicles, pilots and aircrews need to have ongoing, trusted data. But on the battlefield, electronic warfare has become a serious threat to mission success, as GPS/GNSS jammers are now particularly readily available. For less than 100 euros, anyone can buy a jammer on the internet with a performance level sufficient to deny civilian applications within a 50km radius.

Military jammers are highly effective in the most challenging military environments, capable of handling all types of threat scenarios from multiple low-cost jammers to high-power ground jammers, including multiple precision and airborne jammers.
By combining the signals from the unique antenna configuration into the antenna electronics unit, jammers or spoofers can be detected and their effects removed to maintain the continuity of GPS/GNSS information.

With an anti-jamming solution installed on their platform, military jammer end users can rely on their GPS/GNSS signal and successfully complete their mission.

In general, electronic stations are very important for the future development of every country. Military shields are a big investment in every country that will invest a lot of manpower, material and financial resources to develop continuously.

The United States has traditionally received calls from Northrop Grumman’s proposal to represent the development of early ecm applications to support electronic warfare.
The United States accompanied Northrop Grumman in announcing that it has submitted a bid for the Navy’s next-generation jammer technology maturation stage. Titled an Operational Procurement Agreement, the Navy is applying to replace the current ALQ-99 jammer group.
The Navy’s jamming technology is designed to address enemy threats in the modern electronic battlefield environment. ALQ-99 is a pre-digital technology that must be updated with next-generation capabilities.
“The first shot in combat is no longer bullets, but electrons,” Stephen Hogan, vice president of information operations and electronic attack at Northrop Grumman, said in a statement.
“We see how the Russians use electronic attacks in Georgia, and we see every day how terrorists operate, using purchased electronic equipment to harm our soldiers and pardoned civilians.”
In addition, the United Nations has also asked Iran to remove military signal jammer.

The United Nations Telecommunications Organization has declared that Iranian communications barriers to satellite communications are illegal. The International Telecommunication Union accused Iran of making all the blocks.
MTS has brought charges against Iran over a complaint from one of the satellite communications users, Eutelsat. Two applications were submitted to demonstrate that communications were blocked.The European Community condemns this behavior by the Iranian authorities with regard to online censorship.

The Navy Times reports that the U.S. Army has recently fulfilled four contracts involving the development of next-generation jamming electronic warfare systems. The new system is touted to replace the ALQ-99, a new military jamming system that acts like a shield to protect U.S. aircraft from enemy missiles. The U.S. Navy is currently planning to invest $4 billion in the development of this new generation of military signal jammer.

The new version of the military jammer is highly efficient at interception; it processes the signal automatically, and even jams the received signal of said radio frequency, while it is able to detect and locate the source of these signals.

Electronic warfare aircraft find ample use in today’s combat operations. So, with the number of roadside bombs rising dramatically in the Taliban and Afghanistan, the U.S. military is now rushing to get the latest upgrade in jamming weapons, not just relying on radio and cell phone communications.

The best solution to this problem is to develop a better jamming system that is more efficient, stealthy, has a longer range, and can even hit targets protected by modern defense networks; the Pentagon, which needs to work now, is considering this .

Not only that, but the Air Force is also working on a new system to locate military GPS jammers from enemy satellites.
