GPS finds major use in most equipment and systems to provide location information instantly both in civilian and military applications. These devices use the signal received from a minimum three GPS navigational satellites or more to calculate the location information. The use of GPS Systems helps terrorists to navigate both on land in mountains, jungles or desert terrain thereby providing them with a high degree of mobility and action capability. Availability of UAVs or drones with GPS capability also provides capability to terrorists to have surveillance of potential target sites for reconnaissance. This provides them the capability to cause death of both civilians and security forces as well as destruction of property and infrastructure giving them high visibility for their cause. There is extensive use of GPS in military equipment and systems both on man-pack and vehicular basis enable forces to move accurately during operations both during day and night.
Type of GPS jammers is Area Protection System against Satellite Navigated Hostile Threats which is a system designed to protect specific locations against missiles guided by GPS. It will effectively protect a well defined area from ground and sky threats while it will not, in any way, affect normal operation of navigation services outside this area. This is very useful to protect important locations like power generation facilities, national government or military headquarters or other critical sites from attack using GPS guided weapon like missiles or bombs.
Can provide cover for military signals from 10km to 150km and for civilian signals it varies between 30km to 350km. The range depends on power amplifier and Antennas used and the total number of bands simultaneously active at a time. It also depends on the type of terrain and natural obstacles in the area.
The type of signal jammer and their utilization can be customized depending on customer requirements and deployment envisaged. also prides in the intimate maintenance support provided by it during warranty and the entire equipment life cycle for the complete satisfaction of its esteemed customers.
Using triangulation, GPS can deliver the location to the receiver within centimeters of its exact spot.
It is important to note that GPS radio mobile signal jammer use a specific frequency. There are actually two major frequencies that GPS work on: one is for public, non-military use (1575.42 MHz) and one that is used solely for the US military (1227.6 MHz). Because GPS is nothing more than radio waves, these waves can be jammed, though technical devices and expertise are needed for that purpose.
While GPS jammers have been created (specifically by the government, military organizations and spy or privacy gadget companies), most civilians do not have the technical capabilities to create their own home made device. It is much more difficult than just blocking a radio signal with basic radio interference.
Most GPS Jammers are built for military uses, for instance, to confuse the enemy on where their exact location is or where the enemies GPS guided missiles or bombs will fall. However, there are a few civilian uses for jamming GPS signals including the ability to conceal oneself or one’s vehicle in the case that it is being tracked by a GPS receiver.
It should be noted that most GPS jammers are illegal to build or use in many countries or localities due to the potential for misuse. For instance, a GPS jammer can confuse aircraft and other vehicle instruments, possibly causing mishaps. Some GPS jammers state that they are only for civilian GPS jammers only; however some military equipment, must first sign onto the civilian GPS radio frequency in order to gain access to the military GPS frequency.
GPS jamming is a continuing threat. A detailed understanding of how the available jammers work is necessary to judge their effectiveness and limitations. A team of researchers from Cornell University and the University of Texas at Austin reports on their analyses of the signal properties of 18 commercially available GPS jammers.
Many more likely go undetected each day. In 2009, outages of a Federal Aviation Administration reference receiver at Newark Liberty International Airport close to the New Jersey Turnpike were traced to a $33, 200 milliwatt GPS jammer in a truck that passed the airport each day. And in Germany, some truck drivers have been using jammers to evade the country’s GPS-based road-toll system.
The U.S. and some foreign governments have enacted laws to prohibit the importation, marketing, sale or operation of these so-called personal privacy devices. Nevertheless, a certain number of jammers are in the hands of individuals around the world and they continue to be available from manufacturers and suppliers in certain countries. So, GPS jamming is a continuing threat both at home and abroad and a detailed understanding of how the available jammers work is necessary to judge their effectiveness and limitations. This information will also help in developing countermeasures that could be incorporated into GPS receivers to limit the impact of phone jammer.
Jammers constitute an enemy force, and as the Chinese General Sun Tzu stated in the Art of War more than 2,000 years ago, battles will be won by knowing your enemy.
We all know that our wi-fi enabled devices can occasionally just lose a signal. Chances are, that’s a result of an unintentional interruption in communication. It doesn’t necessarily mean that someone’s lurking nearby, purposely disrupting the device and causing you to lose your signal.
However, when a cell phone jammer is being used, it can block any device within a certain range from connecting and communicating. Whatever device is using the same frequency, the jammer can prevent any incoming or outgoing communication.
Jammers are a direct safety threat. It’s obvious that blocking someone from using their cell phone for communication would cause quite an issue. However, most jammers aren’t sophisticated enough to differentiate which signals they’re blocking, therefore causing much more serious issues.
Using a transmitter to affect simple communication might seem like a prank or a silly joke, but these devices could also impede nearby emergency communication. They could also affect a wider range of communication, causing issues on many levels.
Jamming a GPS signal could result in someone not being able to dial 911, or the emergency services being unable to find that person.
While there’s no simple way for the average human to block a jammer, you can detect whether or not one is being used on your signal. You may be able to find where the transmitter is located, and then turn it off. Of course, this probably isn’t very safe, depending on who is using the jammer especially since they’re engaging in criminal activity.
Maybe if you’re an experienced hacker then yes, you may be able to jam the jammers gps. But that would also involve illegally blocking a signal and making you just as culpable as the one doing the first jamming. Then you’d be guilty as well, and that all sounds like a terrible idea.
The way we communicate has changed a lot over the years. From handwritten letters to electronic e-mails to smoke signals and text messages, the way we exchange messages have developed so much thanks to the help of technology.
Probably one of the most ground-breaking inventions in the communications field is when the wireless signal transmission was discovered. As expected, this development came with a pair—in this case, the science of signal jamming. To explain it simply, signal jamming happens when a device’s frequency collides with another signal of the same frequency but at higher power. When this happens, the receiving device will not be able to process signals properly and stop functioning correctly.
It is also not uncommon for signal jammers gps to be used in situations like VIP transport and transfer. Rather than blocking the transfer of communication signals, however, specific signal jamming devices are also used to render a certain area radius safe from the detonation of bombs, particularly improvised explosive devices. These types of signal jammers work by countering the signals that can otherwise set off explosives.
Signal jammer devices used for WiFi are usually employed by companies and organizations that need extra protection against data theft. Many companies opt to have it to prevent information leaks that can cause expensive data loss.
Cell phone jammers are a type of jamming device that blocks the signals that smartphones receive. It can help keep individuals safe from pesky calls and usually work only on limited spaces. There are even portable models of such devices that are specifically designed to be light so that a person can easily take it with them as they move.
Signal Jamming may have a shaky start in history but the method does prove itself useful for modern situations too. Granted that personal use of it is commonly not allowed by most governments, it pays to know that it can also be used for other meaningful purposes as well.
