10:17 What is dangerous cheap gpsjammers | |
| In January 2007, in San Diego began to happen strange things: ATMs stopped working, lost mobile, disrupt the system monitoring flights in the airport, etc. The chaos lasted for two hours until they find out the reason: near the coast there were two U.S. Navy warships, which carried out a study simulate the conditions of loss of communication. For this system has been activated jamming GPS. By mistake, the signals of satellite communications not only drowned out by the ships, but in the city of civilians. The one case showed how important is the GPS for various health services. It turns out that cell tower, electric networks, information banking system and even the stock market - they all rely on the time signals from satellites GPS. According to some experts, our dependence on GPS is becoming too dangerous, given the extraordinary precariousness of this technology. The problem is that the satellite signal is very weak, and drown it extremely easy if the noise generated at the same frequency. The signal can drown out a primitive device made in China, which is sold in shops for $ 30. Although the device is prohibited for use in most civilized countries, but demand is still there and, therefore, appears and offers - in China, such devices have already gone into mass production at local factories. Customers - usually drivers of commercial vehicles who want to avoid tracking by the employer. The device used Theft Auto and to suppress the tracking system in a stolen car. Radius car jamming is very low. But the hypothetical terrorists or fraudsters can use and more powerful devices, similar to those used in the U.S. Navy near San Diego. It is terrible to imagine what chaos will arise in the modern metropolis, if someone activates such jammers sufficient power. Damage can be more terrible than any terrorist attack. It is surprising that now the various emergency services, including ambulance, the Emergencies Ministry, the military, the control system on flights and rail transport, electricity - all together switching to satellite coordinates and time signals, without worrying about creating a backup system. According to the magazine GPS World, now in the world is using more than a billion receivers GPS, and more than 90% of them are only used for precise time signals. I wonder that enthusiasts have created working samples of the new generation of devices that can not just turn off, but distort signals GPS. Fraudsters can use this to implement certain major frauds (eg, all applications in the stock market marked time signal so that the sabotage of a competitor's network will manipulate the stock quotes). By some estimates, the mass production cost of such devices range from $ 500 to $ 600. | |
