GPS jamming systems are in widespread use
TOO MANY PEOPLE are using illegal GPS jamming devices on UK roads, according to a study, and are putting critical emergency systems at risk of failure.
A two year research project called The Sentinel deployed specially developed GPS interference probes to detect parts of the UK where GPS signals suffered interference either from natural sources or deliberate jamming.
Initial findings using six months' worth of data from 20 probes suggests that between 50 and 450 incidents of deliberate GPS jamming take place every day across the UK.
That points to widespread use of GPS jamming devices, said Bob Cockshott, director of position, navigation and timing at the ICT Knowledge Transfer Network. "These jammers present a very real risk to services that rely GPS," he told The INQUIRER.
These GPS jammers are often bought over the internet and the researchers believe that they are typically used to interfere with the GPS trackers used by logistics firms to track their vehicles.
While this often meant that they were used by drivers not wanting to be caught out when taking an on-duty nap, there have been cases of the devices being used to hide hijacked vehicles.
One of the major problems is that the devices are often far more powerful than users expect. As a result, they can potentially interfere with GPS systems at airports, which are usually sited near major roads, said Cockshott.
In the future, those using jammers look likely to extend their capabilities by spoofing signals or sabotaging time stamps, warned Cockshott.
The Sentinel project is a collaboration between Chronos Technology, which provides the interference-detecting probes, and the ICT Knowledge Transfer Network, the National Physics Labororatory, the Association of Chief Police Officers and others.
Ultimately, the Sentinel project is intended to help law enforcement agencies identify those responsible for jamming GPS signals and provide countermeasures, said Charles Curry, CEO of Chronos Technology.
"We are making great strides in the detection and location of these devices, the final stage, mitigation, is still some way off depending on the application and industry sector," he said.
Last year, the Royal Academy of Engineering warned that the UK's critical systems have become too reliant upon GPS technology. µ

People can use different GPS jammer models. If someone uses GPS jammer with few hundred meters blocking radius - they are doing wrong thing, endangering other people around them. Jammer Store Inc. manufactures small GPS jammers designed specially for car usage. They have 5 meters radius, allowing drivers to continue protecting their privacy rights while not harming ships, airports and other important institutions.
It's companies lack of trust for their employees fitting GPS to track them in company vans.
If you remove the root cause - the trust issue - people wouldn't have to be tracked. So either employees should stop taking the mick and skiving off or employers should stop worrying about employees taking a few minutes of paid time out. Either way, remove the GPS trackers and people will stop using jammers.
So that's what happens if you use GPS too much as a weapon against people's freedom then.
And their solution is making things even worse, and they think that will improve things over the longer run too I bet.
