Navy ship blocks GPS satellite signals over large area while training in Port of San Diego
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.
