Criminal gangs have begun to introduce, with the help of Car GPS jammers from China for stealing luxury cars and lorries with valuable cargo C and there is a fear that terrorists are using more powerful models for Travel Air will hold a conference in London Hearing Tuesday to intervene.
The Jammers is on the same radio frequency for Global Positioning System (GPS), the hit signal timing devices that drive the chart position. This means that a tracker device in a truck with a valuable cargo, or a anti-theft car GPS device in case of theft, the report should distinguish the right to build a brand GPS.
It disappears from the radar screen, said Professor David Last of the University of Wales, Bangor, police seized an expert in certain cases during the past 18 months have GPS interference.
Some German drivers suspected of using jammers to escape from the GPS for road pricing, which has been introduced for trucks in 2005. There were also attacks in Russia, where such jammers used against both GPS and mobile phones in trucks to prevent the driver to communicate with the authorities.
In Germany as in Britain, it is illegal to sell or use such jammers C, although it appears to be legitimate the importation or possession.
Compatible devices proud to be able to see at least four of 30 satellites over 20,200 kilometers (12,550 miles) above the Earth, by correlating the timing and exact recognition of signals transmitted on the floor can be a location device within its own calculations of about 1 meter. But this is not the fault does not share the devices send a signal to the GPS signal interfere.
The problem is that the signal is very low, C is the equivalent of leaving a lumen 25 watt light bulb for the satellite, said Bob Cockshott, another speaker, place and time is the program towards Strategy of Technology, funded by the Ministry of Economy, innovation and skills.
This means that there should be a jammer with a capacity of about 2 Watt for each of the signals from GPS satellites in an area a few meters away from the swamp. This facility will be billions of times stronger than GPS signal area.
These systems were found arrested in the hands of criminals by the police during the past 18 months, said Cockshott. Blockers may be made by a competent electronics engineer, if bands like to make it appear by Chinese manufacturers to introduce Shenzhen.
We need the GPS users aware of the risk, said Cockshott. You need to use a complementary technology to ensure that their systems, even without the GPS. Systems, triangulation of cellular towers and d others who have used a terrestrial network, also called eLoran work if GPS signals are not, he said.
Last teacher said that the use of these systems by criminals and terrorists since 2002 when the U.S. government, the report states that interference with the GPS serious security and economic damage in the United States could expect.
Charles Curry, Managing Director of Time Technology, the leader of a consortium that manufactures GPS interference detection system through a grant 052.2m British government said it was the biggest fear that powerful Jammers GPS to power 20 W or more can the terrorists to the airport to use.
If GPS functionality on a plane or other things based on a certain date, such as emergency services and electricity is lost, if not reduce the ability to resist these attacks could build very serious consequences. The detection system currently at the prototype stage and will be in airports, ports and other places used to use for the production of nanosecond accuracy GPS.
