GPS stands for global positioning system. It is used for navigation purposes by individuals, commercial entities and the military. GPS USES 24 satellites that orbit the earth and send radio signals. GPS satellites, used in conjunction with GPS receivers, can now be found in personal handheld devices, car navigation systems, ship navigation systems, high-precision commercial products and a variety of military equipment.
Jamming devices are rf transmitters that intentionally block, block, or interfere with legitimate communications, such as cell phone calls, text messages, GPS systems, and wi-fi networks. Previously, such equipment was made for military purposes. While GPS jammers have been made (especially by governments, military groups and spies or small privacy companies), most civilians do not have the technical ability to create their own homemade devices. This is much more difficult than blocking radio signals with basic radio interference. Most GPS jammer, for example, are used for military purposes to place an enemy at its exact location or where an enemy GPS missile or bomb is falling. However, there are some civilian USES for jamming GPS signals, including the ability to hide oneself or a person’s vehicle while the GPS receiver tracks it. “The stakes are high for GPS to be so embedded in transport, manufacturing and the economy of our society,” said David rust, emeritus professor at the university of bangor in the UK and a leading authority on the criminal use of GPS jammers. “This is especially true in telecommunications: GPS is the best source of opportunity for most of our phone systems, the Internet, and cell phones in the United States.” Michael halcovay, chief executive of the high power blocker store, told FoxNews.com that GPS blockers can be easily stored in a car or bag and can help avoid spy detection – for example, from a spouse who suspects infidelity and is equipped with a GPS tracking device like the Zoombak in a car. “The GPS blocker will help you protect your privacy,” Kharkovoy said. “Perfectjammer GPS jammer type GJ6 is used to block all possible tracking systems and all civilian GPS systems including GPS L1, GPS L2 and GPS L5. To run the GPS jammer, all you have to do is turn on the switch on top of the jammer.” “It depends on the capability of the jamming device.
