What Type of Anti Jammer Should You Buy?

Anti Jammer

When deciding what type of Anti Jammer to buy, you’ll want to consider the brand name and manufacturer. You’ll likely find many companies offering the same type of devices, so make sure you research each before you make a purchase. Here are four of the most popular models on the market. Knowle, CRPA, Raytheon, and GAS-1 all offer different types of anti-jammer technology. These devices are often quite quiet during the discovery phase and can be virtually undetectable to your neighbors.


In the 1990s, the U.S. military was in the midst of a Navigation Warfare program. They sought enhanced protection from jamming threats. This led them to develop the Advanced Digital Antenna Production (ADAP) system. The system was introduced in 2006 and quickly became a de facto standard for anti-jamm technology. Even 20 years later, the system continues to be fitted on numerous platforms.

The GAS-1 uses dual technology to track and identify jammers faster than its competitors. The dual antennas are designed to detect multiple sources of deliberate jamming and reject them to ensure that navigation equipment operates effectively. The GAS-1 Anti Jammer is an excellent option for military use, allowing aircraft to approach jammer-protected targets much closer and enhance mission assurance. These systems are also available with multi-element CRPA, which uses post-correlation nulling techniques to detect the presence of a jammer.

The UK’s Ministry of Defense awarded Raytheon UK a contract to develop advanced GNSS anti-jamming technologies for military and civil applications. The company’s Assured Positioning Navigation and Timing business will deliver the Technology Demonstrator Programme and integrate advanced multi-element Anti-Jam technology. Cobham Ltd. is expected to win the contract to research and develop advanced anti-jamming technology.

GPS jamming is a serious threat to the U.S. Army. They faced jamming attacks in Europe and Afghanistan and a recent Presidential Directive by President Obama addressed this concern. In 2013, the US Army launched a program called Assured Positioning, Navigation, and Timing (A-PNT), which requires cooperation between military and foreign forces. The A-PNT program has a specific mission of improving navigation warfare capabilities.

The growing commercial use of drones can provide a significant market opportunity for GPS manufacturers. Drones are highly vulnerable to jamming. As the use of drones increases worldwide, GPS anti-jamming technology will continue to gain in popularity. In addition to military applications, the GPS anti-jamming market will also expand as more drones are purchased. Moreover, drones will continue to become a major source of jamming.


The KNOWLE Anti Jammer is a new solution for mobile phone-based WSN. It uses a notch filter to boost signal strength by about 5 decibels. The proposed solution can detect jamming devices and only activate it when there is significant jamming power detected. This enables it to operate in both military and civil scenarios. It also reduces energy consumption. In addition to enhancing quality of service, the KNOWLE Anti Jammer reduces the overall energy consumption.

The KNOWLE Anti Jammer’s sensitivity is enhanced by the fact that it has a small range. The spatial position of the jammer can be changed by dynamically adjusting the parameters. These parameters include sampling frequency, duty ratio, bistatic angle, and target’s equivalent angular velocity of rotation. The main simulation parameters are discussed below. In addition to the sensitivity, it has other beneficial effects such as interference reduction.

The KNOWLE Anti Jammer’s discrimination efficiency improves dramatically as the correlation coefficient changes. When the correlation coefficient decreases to 0.4, the discrimination probability decreases to under half of one percent. In contrast, if the correlation coefficient reaches 0.7, the discrimination probability remains higher than 85%. Therefore, the proposed algorithm is far superior to other algorithms and can be applied in more complex environments. This makes it an excellent choice for any type of jamming application.

The KNOWLE Anti Jammer is capable of reducing the power of other devices. Its power output is proportional to the spectrum available. When frequency-hopping is used, the power output of the KNOWLE Anti Jammer is multiplied by 500. The output power of a KNOWLE Anti Jammer is approximately one-third of the total power of all other jamming devices. This is the only jamming solution that can reliably block over 95% of all wireless signals.


CRPA technology is a powerful jammer-defeating system that exploits the spatial diversity of signals. Both jamming and desired satellite signals originate in different directions. By using an array of antenna elements to block the signal from certain directions, a CRPA is able to effectively eliminate the jamming signal while still letting through other signals. It was originally developed in the UK and has been upgraded over the years. The latest generation of CRPAs can defeat up to three jammers simultaneously.

The evolution of CRPA technology has meant that the technology can be packaged into a smaller, self-contained antenna enclosure. One design, called the Landshield, has migrated the null-processing device into the CRPA antenna enclosure. Commercial versions of the device use the same hardware as the CRPA antenna and antennae, allowing it to perform CESM and other functions in conjunction with the CRPA.

The CRPA technology works much like noise-canceling headphones. Outside noise is often a hindrance to communication. This technology is attached to an Antenna Electronics module that takes the GPS signal and combines it with noise to minimize the jammer’s noise. This allows the CRPA Anti Jammer to be used in vehicles as a GPS-shield and can protect them from jamming from other devices.

CRPA-based GPS antennas are the ideal anti-jamming solution for many applications. They eliminate interference and support critical missions. Their novel beamforming techniques eliminate multiple sources of interference, ensuring that a GNSS receiver can continue to function properly even when there is multiple jamming sources. The wide bandwidth of CRPA-based GPS antennas provides flexibility in addressing a variety of jamming challenges.

A CRPA antenna integrates with military satellite navigation receivers and can recognise multiple sources of deliberate jamming. The integrated system allows a vehicle to approach and engage a target with less risk of being jammed. It also improves mission assurance. CRPA antennas are already being used on the mine-destroying ship Kormoran II. If you’re planning to purchase a CRPA antenna, don’t hesitate to contact a reputable dealer today.


Unlike the previous generation of jammers, the Next Generation Jammer Mid-Band provides the EA-18G Growler with enhanced airborne electronic attack capabilities. The system uses digital, software-based, and Active Electronically Scanned Array technologies to disrupt enemy technology. Unlike older jammers, the NGJ-MB provides operators with the flexibility to use non-kinetic attacks to gain the upper-hand over their enemy.

With its integrated power solutions from GPS, military forces can pinpoint their location. Unfortunately, spoofing is a common enemy countermeasure and a prime target for jammers. The anti-jamming systems from Raytheon UK protect this weak point in modern infrastructure systems by identifying and nullifying fake signals. It is capable of blocking the signals from six different jamming entities and can be used with manned and unmanned aircraft platforms, ground-based platforms, and weapon systems.

The technology also helps protect GPS systems. The technology works with the antenna view of the satellites to block jamming signals. It is available off-the-shelf, allowing rapid deployment. It works with any installed GPS receiver and supports M-Code. Furthermore, the GAJT is capable of operating 100 times closer to a jammer than a system without protection. The system’s entire performance is the sum of the GAJT interference suppression plus the installed receiver.

The Global Anti-Jammer market is segmented according to country/region. Various countries and regions are actively competing in the market. Some of the key players in the market include Raytheon and NovAtel. Both companies hold a significant share of the market in revenue. The Global Anti-Jammer market is forecast to reach USD 6022.3 million by 2027. It is expected to grow at a 4.9% CAGR during the forecast period.

Despite the threat of jamming, the technology is also available to protect GPS signals. The global defense budget will be US$2 trillion by 2020, with the United States being the largest spender. With the proliferation of sophisticated anti-jamming solutions, the U.S. is investing in this emerging market. This innovation in GPS technology is helping the country protect its military against jammers. The MALD-J is capable of combating intentional jamming and mutual interference. It is ITAR-free and Raytheon owns the intellectual property rights to its technology.
