Concern grows over GPS jammers

  • 06 December 2013
  • By Chris Tindall

Fleet managers should wake up to the problem of drivers using easily-obtained GPS jammers to prevent their vehicles being tracked, according to the head of a firm investigating their use.

Charles Curry, managing director at Chronos Technology, said he believed instances of jamming, using products bought cheaply over the internet, were on the increase and had the potential to cause chaos.

Chronos was involved in a recent project to gauge the frequency of GPS jamming events on motorways and urban and rural destinations across the UK and the results showed regular use of devices by motorists.

Jammers swamp the signal used by firms to keep track of their fleet, making them ‘disappear’ off the radar.

“There are 60 websites selling these things,” said Curry. “The big worry for the fleet manager is his own drivers who might want to do something that doesn’t relate to what they do officially for the company. We have instances of this.”

In 2010, criminals used jammers to prevent LGVs from being tracked in order to steal metal worth £6m. Two men were later jailed for a total of 16 years.

Professor Bob Cockshott at the National Physics Laboratory said: “Companies using tracking for their business purposes, for asset control and control of their vehicle fleet, if an employee can interrupt the system then it must be a worry to them.”
