Officials of the Department of Homeland Security said at a GPS meeting on Tuesday that detectors installed in tact toll stations can help locate GPS interference sources. The United States Federal Aviation Administration (Federal Aviation Administration) has identified a GPS system failure that can provide accurate landing information for Newark Liberty International Airport. Officials ultimately attributed the problem to the truck driver of the adjacent New Jersey toll road, which used jammers to avoid the company’s operations center. But the search took a year and a half.
John Merrill, DHS location, timing and navigation project manager, said a faster way to find jammers is to install sensors at the toll booth and use them in conjunction with camera systems to identify vehicles equipped with the device. Civil GPS Service Interface Committee meeting in Nashville. The Federal Communications Commission prohibits the sale and operation of all signal jammers, including GPS jammers. According to Merrill, in an Internet search before the conference, the word “GPS jammer” had nearly 2 million hits. These devices can be purchased online for only $30.
In a speech to the Telecommunications System Synchronization Workshop in Broomfield, Colorado, Merrill Lynch pointed out that the FAA and FCC need to find gps jammer operating on New Jersey toll roads by April 2019. The Federal Aviation Administration (FAA) suspected interference in 2018, but it was not until February 2019 that the Federal Aviation Administration (FAA) and the Federal Communications Commission (FCC) deployed radio frequency detectors and found that the source of interference was moving and slow. Only then began to find out the problem. In the end, they used both mobile and fixed capture equipment and cameras to locate the truck and grab the equipment.
According to Merrill, DHS has developed a national interference detection system called Patriot Watch, which will input FAA and FCC information into a database that analysts can use to find fault signals. Merrill Lynch said at the Nashville meeting that since the development of GPS in 1973, it has become an important part of many critical military and civilian infrastructure systems. The system is now essential for flight, sea and ground operations. They also provide accurate time signals for the operation of wired and wireless networks. Colonel Bernie Gruber, director of GPS at the Los Angeles Air Force Space and Missile Systems Center, said at the meeting that there are currently approximately 1 billion civilian GPS receivers in use. Since 1976, Russia has been developing its global navigation satellite system. There are currently 24 satellites in orbit, compared with 31 GPS satellites. Many manufacturers have started to produce dual GLONASS/GPS receivers, which are more accurate than GPS receivers. Ray Clore, a senior GPS consultant at the State Department’s Space and High-Tech Office, said at the meeting that Russia hopes to establish a GLONASS surveillance site in the United States. Discussion on this issue is still ongoing.
