Hazard from GPS jammer

For only $ 50, one can own a GPS unit that is both compact and easy to use. With this 'security', terrorists can 'down' commercial aircraft carrying hundreds of passengers.

This is a warning from Fox News in an investigative report released on March 19 on the dangers of the equipment being sold on this network.

According to investigators, the GPS jammer transmits a low voltage signal, generating signal noise and possibly fooling GPS receivers that satellites are not available. They can also be used to disturb the police and evade pursuit.

In fact, car thieves in the UK have used this device to escape. Even some use this jamming device to 'irritate' iPhone users. But the real danger that this device causes can not be calculated.

GPS jammers can pose a great deal of danger.

Some experts fear that terrorists may use it to disrupt GPS receivers on planes, although according to some experts, the risk is not high because radar uses radar. Land navigation and also the support of air traffic does not depend on satellite.

Recognizing this danger, the George Bush administration in 2008 set out to create a high-voltage ground-based system called Enhanced Loran (eLoran) to "jam" noise. However, Washington has not shown any intention yet with eLoran. GPS jammers are still considered illegal in the United States and the Federal Communications Commission (FTC) has announced that it will prosecute any case of allegedly importing or possessing this device. .

However, the Fox News investigation reported that GPS jammers are cheap and can be purchased easily online. Fox News has bought the device for $ 50 from various online sources, from Sweden to Hong Kong.
