How Signal Jammer Cell Phone Blocker Has Changed

There are some civilian uses for jamming GPS signals, mostly privacy related, including the ability to hide yourself or your vehicle in case a GPS receiver is tracking it. A practical application would be a salesperson or the delivery person who might want to have lunch outside of their territory or return home for a forgotten item without having to do a lot of explanation based on the GPS location on their vehicle. Most civilian GPS jammers have a range large enough to cover even the largest vehicles and provide privacy for users.

The interference source has not been determined. Probably from a GPS jammers. These devices are sold as “data protection devices“ and can be purchased on the Internet for $30.These are legal to own, but illegal to operate in Britain. They are commonly used by truck drivers and others who do not want to record the vehicle's location but interfere with all GPS receivers in line of sight.GPS signals from orbiting satellites are very weak, equivalent to the brightness of a car's headlights at 19,000 km. So it's easy to be overwhelmed by nearby transmitters, which are not more powerful than mobile phones.

The incident has raised questions about the safety of civilian drones, particularly large ones that pose a risk of significant harm to personnel. Planned drone delivery services, such as Google to get 0.0% Wing and Amazon Prime Air, require powerful navigation capabilities that will not deviate from course or crash when interfered with by GPS. Especially when a lot of people don't like drones flying over cities and are ready to take action against them.GPS accidental interference is also an increasingly serious problem. In the United States, there is concern that Ligado Networks‘ 5G transmitter will interfere with accurate GPS within three kilometers (the same as survey drones).

The incident also highlights the need for military drones to use Global Positioning System methods of navigation. Now, military-grade GPS jammers and anti-theft devices that provide the wrong location are used as anti-UAV defenses. Iran claimed that it used GPS to trick the American RQ-170 outpost into crashing in 2011. This kind of equipment is increasingly available in the commercial sector and may come from China, which seems to be using the technology to protect government assets.

The Global Positioning System is a military system operated by the U.S. Air Force. At present, it is being upgraded, called GPS Block III, and it is worth more than $5 billion. However, doing so does not necessarily help to prevent such incidents.

Dana Goward, Chairman and Director of the Resilient Navigation and Timing Foundation, said: “Low power consumption means that GPS is indeed very easy to destroy.“ “GPS III provides special equipment for military users to improve its resistance to congestion, but 99% of civilians user have no additional benefits at all.”

Goward said that GPS is feasible and powerful and more resistant to local interference means building a broader infrastructure and integrating powerful ground transmitters and satellites.

“We must consider the overall architecture. What we need is a layered architecture with GPS and other satellites, such as eLoran, which can achieve powerful, terrestrial, and difficult-to-break regional coverage, as well as Wi-Fi, cellular towers, and inertial systems. And other methods for local strata,” Goward said.”.

Driverless aviation accidents and incidents in the UK, with no casualties, do not seem like a big deal. But some people may think this is a sign of coming.
