Officials from the Department of Homeland Security said at a GPS conference on Tuesday that detectors installed at toll gates will help identify the source of GPS. The Federal Aviation Administration (Federal Aviation Administration) has discovered a malfunction in the GPS system, which can provide accurate landing information for Newark Liberty International Airport. Authorities ultimately blamed the problem on truck drivers on the adjacent New Jersey toll road. Truck drivers use jammers to avoid the company's operations center. However, the search took a year and a half.
According to John Merrill, the positioning, timing and navigation project manager of the Department of Homeland Security, the faster way to find signal blocker is to install sensors at toll booths and install equipment in conjunction with camera systems. He said this is to identify vehicles. Civil GPS Service Interface Committee meeting held in Nashville. The Federal Communications Commission has banned the sale and operation of all jammers, including GPS jammer. According to Merrill, Internet searches before the conference found that the word "GPS jammer" had nearly 2 million hits. These devices can be purchased online for only $30.
In a speech at the Telecom Symposium in Broomfield, Colorado, Merrill Lynch pointed out that the FAA and the Federal Communications Commission need to find GPS interference operating on the New Jersey Turnpike before April 2019 Device. .. However, it was in February 2019 that the Federal Aviation Administration (FAA) and the Federal Communications Commission (FCC) deployed radio frequency detectors and discovered that the interference source was moving and slow. Then I started to find the problem. Ultimately, they use mobile and fixed capture devices and cameras to locate the truck and grab the device.
According to Merrill, DHS has developed a national interference detection system called Patriot Watch. It inputs FAA and FCC information into a database, which can be used by analysts to find fault signals. Merrill Lynch stated at a conference in Nashville that since the development of GPS in 1973, GPS has been an important part of many important military and civilian infrastructure systems. The system is now essential for flight, sea and ground operations. It also provides accurate time signals for wired and wireless network operations. Colonel Bernie Gruber, GPS director of the Los Angeles Air Force Space Missile System Center, said at a meeting that there are currently about 1 billion civilian GPS receivers in use. Since 1976, Russia has been developing a global navigation satellite system. Currently, there are 24 satellites in orbit, but 31 GPS satellites. Many manufacturers have begun to manufacture dual GLONASS/GPS receivers that are more accurate than GPS receivers. At the meeting, Raycroix, a senior GPS consultant in the Office of Space and High Technology of the US State Department, stated that Russia hopes to establish a GLONASS surveillance site in the United States. Discussion on this issue is still ongoing.
