　　GPS has become an "invisible utility" that we unknowingly rely on.Signals from GPS satellites can now help you call your mother and even land your plane - but a cheap tin box can disrupt it all In January 2007, two Navy ships in the Port of San Diego had been training.Technicians jammed the radio signal in order to test the program when communications were lost.

　　One GPS jammers can take out GPS from several kilometres away, if unobstructed.Some are worried that we are now leaning too heavily on a technology that can all too easily fail – and it doesn't need a freak navy training exercise to cause havoc.Unwittingly, they also blocked radio signals from GPS satellites in large swathes of the city.Cell phone companies use GPS time signals to coordinate how your phone talks to their cell towers.

　　Banks and stock exchanges use these satellites as time stamps to prevent fraud.These can be bought on the internet, and tend to be used by say, truckers who don't want their bosses to know where they are.At the same time, our society's reliance on GPS navigation is increasing year by year.Why would a GPS outage cause this outage? These satellite signals now do much more than inform a car's sat-nav.

　　But why do people need car signal jammer? Often, the device has been used by car robbers across the UK to snatch luxury cars and trucks loaded with valuable cargo, undetected by the authorities via satellite. A Jammer is a useful tool for people who regularly violate traffic laws to help them break traffic laws and hide from law enforcement authorities.

　　Energy providers use GPS to synchronize grids when connecting them together.No surprise, then, that researchers across the world are scrambling to find ways to prevent disastrous GPS outages happening.Their biggest concern is a GPS jammer – a plastic device that can sit on car dashboards.Their increasing use has already caused problems at airports and blocked cellphone coverage in several cities.

A power outage in the US was caused by a GPS glitch in 2006 Enable GPS blocker to prevent package tracking device from sending location signal GPS stops theft when traveling, but Jammer stops GPS Floodlights scare away potential thieves, but not thieves with jammers Criminals using jammer equipment steal construction company heavy machinery every year More than 700000 stolen cars in the United States fail to work due to jammers Some use jammers to interfere with GPS tracking used to monitor marijuana distribution Criminals use signal jammers to interfere with GPS tracking of police cars GPS device mounted on parolee's car tracks whereabouts after release Watch out for GPS Locator to Change into a Listening Device Stealing GPS locator Shield GPS locators on the vehicle during private activities A world without tracking blocks GPS, WiFi and cell phone signals With gps jamme, at least using GPS is not possible One commonly used safety device is the UHF GPS jammer To create a natural environment of equal competition, universities will open jamme Call
