The application scope of space interference is gradually expanding

“The last 15 years have seen a dramatic proliferation of GNSS jamming systems: from the preserve of the military, through criminal groups, to the point where jammers are now sought and owned by everyday citizens seeking to hide from a perceived risk of being tracked during their day-to-day lives.”

Among the companies and organizations working on such systems are Boeing, Raytheon, BAE Systems, Lockheed Martin, CACI, the Dubai Civil Aviation Authority, Sanad Academy, Sensofusion, SystemsGrok, Batelle, Blighter Surveillance, Systems DroneShield, Dedrone, CTS Technology, Theiss UAV Solutions, MCTech, Malou Tech, Guard from Above, Saab, UMS Aero Group, OpenWorks Engineering, Advanced Ballistics Concepts, Snake River Shooting Projects, Department 13, DeTect, Drone Defence, and Liteye Systems. Methods include cell phone jammer and ballistic interception with munitions and nets.

USAF aircrews began flying GPS-denied training sorties in 2010 as part of an initiative called “Readiness Project 2.” In 2013, the service developed a system called Simulated Programmable Aircraft-Embedded Jammer, which can realistically simulate GPS jamming on one plane’s equipment without affecting others.

In reference to the mobile phone, many people firstly think about its convenience brought to our life. While different people in different situations may have different opinions about the same thing. In many situations mobile phone is not as the good as before. For example, mobile phones can cause a distraction in education, especially in school. So there is a hot topic that should the mobile phone signal blocker be used in school. As we all know that, there should be a limited time to learn that is the school. Playing with mobile phone is something many people like, but it can get in the way of the things that we need to do. In classes teachers dislike the continuous rings of the cell phone totally because it will disturb the class order naturally. So many parents and teachers advocate the use of the mobile phone signal blocker in school. Maybe it is not feasible and legal to confiscate the mobile phones of students. But is is polite and reasonable to use the mobile phone signal jammer in class. This is the big role of the phone jammer in education. There should be a time to do the things we enjoy, like pay attention in class.

Another reason why a lot of schools have jammers is to trying to prevent the students from cheating. A cell phone can be an easy cheating device where they can get the answers from a person who has the information or from the internet. It is easy to use a cell phone jamming device, and all you need to do in order to get it started is to push a button in order to interrupt a chat or conversation. Once the device is on, the cell phone will not be able to catch any signal and the phone will lose its value and get the students back in the class.
