What do the Finnish civil aviation pilots who lost their flight signals, show that they are 40 miles on land in the Black Sea, and the American pilots who avoid tolls? In each case, there are interference factors that affect the global positioning system (GPS). What is a global positioning system? The global positioning system is a satellite network that transmits signals. The receiving device uses these signals to determine the geographic location through trilateration. For example, to determine the location on the floor, at least three input signals are required. However, with more input signals, the accuracy will increase. In order to determine geographic location and altitude, there must be at least four signals. GPS not only determines the geographic location, but also provides a key fourth dimension that many people do not know. Each GPS satellite contains several atomic clocks that send extremely accurate time data to the receiver. The receiver decodes the information and allows the electronic device to determine the correct time within one billionth of a second.
Why is GPS important? Countless infrastructure, companies and electronic products are based on GPS time and location synchronization. They include: In addition, many other devices rely on GPS to some extent. As technology advances, the number and types of GPS-containing elements have also increased. Outside the United States, other countries/regions mainly rely on Beidou of China, Glonass of Russia and Galileo of Europe. All these systems and the US GPS system are part of the Global Navigation Satellite System (GNSS). Russia uses jammers to interfere with GNSS. In recent years, Russians have begun to block GNSS. Initially, Russia temporarily blocked or forged GNSS in order to conceal the position of President Putin. The strategy aims to ensure Putin’s safety and prevent weapons based on satellite positions from pursuing Putin.
For example, when Putin crossed the Kerch Bridge from Russia to Crimea, a Black Sea vessel incident occurred. As a result, 24 ships moored nearby displayed their location at Anapa Airport, 40 miles away. Putin’s magnificent summer house near the Black Sea is also protected by permanent GNSS deception areas. This gave his home the same level of airspace protection and GNS interference as the Kremlin.
However, in recent years, Russia has expanded its GNSS interference, prevention and deception. Your gps jammer are so advanced that they may perform a wide range of “attacks” on the GNSS receiver, which may interfere with all navigation systems in the selected area. The use of GPS jammers in the United States is also a problem, and there are threats of GPS jammers in our own countries. Although the United States Federal Communications Commission (FCC) regards GPS jammers as illegal in the United States, they still exist. In 2015, pilots flying to Northeast Philadelphia Airport reported that they lost GPS navigation signals when they approached the runway. The incident was caused by a truck driver who was parked in a nearby parking lot and used the GPS jammer he purchased to disable the locator.
The first GPS Roland in the United States. During World War II, the United States developed a long-range navigation system (LORAN) for fleets and long-range patrol aircraft across the Atlantic. In 1958, the US Coast Guard controlled LORAN. Due to the accuracy of GPS, the Obama administration decided in 2009 that LORAN “no longer serves as a government and is not suitable as a backing for GPS”. The government announced that the system was outdated, and both the United States and Canada closed their LORAN beacons.
By 2015, other countries in the world had closed their beacons. Also stopped the improved LORAN trial version, called eLoran, within 65 feet. The 2018 National Time Flexibility and Security Act created a backup system for GPS, and confidence in GPS for time and place is so important that US Senators Cruz (R-Texas) and Marquis (D-Mass) and Congress Congressmen Galamendi (D-CA) and Hunter (R-CA) worked together to pass the National Time Flexibility and Security Act of 2018. President Trump signed the bill last December.
In addition, the backup system must be used in conjunction with and complement other similar positioning, navigation, and timing systems, including improved remote navigation systems and nationwide differential GPS systems. It should also be able to adapt and expand to provide positioning and navigation skills. In addition, the law provides for the use of applicable private sector expertise to develop, build and operate the system. It must be running for at least 20 years.
Texas Senator Cruz (R-Texas) said in a 2018 press release: “If the current system is only interfered with for a few hours, the American people, the economy and our way of life will face immediate risks. Senators D-Mass added: “The country’s banking, communications, power and transportation sectors rely on GPS timing. We cannot allow this vital system to be harmed by natural phenomena such as solar flares or coordinated attacks such as interference. “The GPS backup system needs further development. In early March, the House of Representatives Committee on Transportation and Infrastructure DeFazio (Oregon) expressed concern about the slow progress of GPS protection: “We are concerned that 14 months after the mandate… became law, And 11 months later it became law. Congress has provided huge amounts of money, and there has been little progress in administration. ”
In the bipartisan letters, Congressman Larson (Washington, DC) and Chairman of the Aviation Subcommittee, Maloney (R-New York), Chairman of the Coast Guard and Maritime Transport Subcommittee, and Galamendi (California) armed The chairman of the force issued a subcommittee on readiness. Request status updates from the Minister of Transport. From the beginning of May, no updates will be publicly available. As the United States increasingly relies on technology to control many aspects of our lives, the fact that this technology requires very precise time has not been lost. As pointed out by the American Telecommunications Industry Solutions Alliance, GPS jammers that cause time issues are a flaw in wireless systems and our growing Internet of Things.
