Interfering devices disrupt normal network order

A properly placed GPS jammer or sprinkler could interfere with signals throughout the United States at a GPS conference in Nashville, Tennessee, a U.S. Department of Land Security official said. At the same time, Cerman Merrill, Program Manager of the US Department of Homeland Security, said at the annual meeting of the Global Positioning Systems Services Interface Committee that the United States is still "insufficient in its ability to quickly identify and identify congestion. I'm doing it. " GPS service deception. Interaction between GPS users in the United States and the world. The United States develops and operates GPS.

Merrill did not define the size of the area where GPS jammers could be turned off, but is now GPS engineer Overlook Systems Technologies Inc. Jules McNeff, Vice President of Strategy and Planning, has been working with the Air Force GPS for 20 years. Year and die. The Vienna company estimates that a 1 watt GPS jammer can cover a medium-sized city. Logan Scott, president of a company with GPS expertise called LS Consulting, was a webinar hosted by Internal GNSS in May, with a 1 / 10th watt GPS jammer of 9.4 miles and a 1 watt jammer. Said to be 29.8. Miles, and watt jammers are 94.2 miles. Inside GNSS are magazines on GPS and other satellite navigation systems operated by China, the EU and Russia. This is called the Global Navigation Satellite System. Consumer GPS jammer with these power levels can be purchased primarily from Chinese manufacturers on the Internet for prices starting at $ 40.

The Department of Homeland Security and the Department of Defense have worked together to develop a jamming location system that can receive jamming signals and route them to the central station operated by the National Geospatial Information Agency since 2010. However, so far, only sensor data. Sent to Newark Liberty International Airport in New Jersey. From March 2009 to April 2011, the Federal Aviation Administration and the Federal Communications Commission discovered only one GPS jammer every two years on the New Jersey toll road. Jammers disrupted the FAA system and improved navigation signals for aircraft near the airport for accurate approach, departure procedures, and terminal area operations.

McNeff cell phone blocker positioning system a "concept" rather than a national operational system. The FAA plans to rely heavily on GPS by 2030, and satellite systems will be at the core of next-generation air transportation systems, by which time VHF radio frequency (VOR) on the ground will be turned off. increase. Interference can affect GPS and other GNSS systems. In September 2012, the FAA established the GNSS Research Group to carry out deliberate sabotage and deception, "technically, politically, legally and operational to mitigate the effects of GPS deception and sabotage. I have identified an opportunity. " FAA Navigation Program Manager Deborah Lawrence said at a meeting that the investigation team would provide authorities with "concrete and actionable recommendations" by the end of September to prevent fraud and interference.
