Are GPS Jammers Common?

There are ways you can use a GPS jammer legally. Just make sure you are aware of your country’s laws and restrictions.

It’s common for truckers to use GPS signal blocker, for example, to stop their management from being able to track their vehicles. Many trucking companies choose to install GPS tracking capabilities in their fleet, but not all truckers are happy about these tracking attempts.
GPS jammers can easily be found and bought online from vendors that globally market their products. They leave it up to the consumer to understand their country’s laws and decide on the use of a GPS jammer.
GPS blockers are usually small devices that plug into a vehicle’s lighter port and emit radio signals that overpower or drown out much weaker signals such as GPS or others. Although GPS jammers are illegal in the US, they are easily available online and are becoming more and more common as the use of fleet management tracking systems increases. These devices may seem relatively harmless at first glance, but their potential to cause harm is significant.
GPS is used for much more than just navigation. It’s also the primary source of timing and synchronization in critical infrastructures such as financial, communications, industrial, the power grid, and more. In fact, these infrastructures are so critically reliant upon GPS for timing and synchronization that over the past several years, the Department of Homeland Security has begun an initiative to raise awareness of the threat and find solutions to safeguard these vital systems.

In timing applications, jammers can disrupt the GPS signal, causing the underlying systems to lose their ability to synchronize their internal clocks and, in turn, their ability to stay in sync with the rest of the network. Since many critical infrastructures sectors require synchronization across their network to be within millionths of a second, even short-term GPS outages can have a major impact. Worse, when an outage occurs, there’s typically nothing to indicate that it’s a result of jamming. The GPS signal simply is not received anymore.

To make matters even more dire, many of the datacenters that house the servers these networks run on are in warehousing districts (with trucks coming and going frequently) or near major highways. These are two of the most likely places to encounter usb gps jammer
