CPS systems easily jammed

• Telematics systems that depend solely on GPS are highly vulnerable to deliberate jamming, a leading system supplier has warned.
'As GPS becomes more commonplace there is a growth in the availability of CPS jamming devices," warns Nick Randall, chief executive of Siemens VDO Trading.
Siemens VDO's own Datatrak network uses low-frequency radio signals for positioning information which Radon says is much harder to sabotage.
However, an Internet search will reveal hundreds of pages about GPS jamming techniques—including some which outline how to put together a simple jamming device that can be built using readily available guidelines and materials for a cost of "around £30-40" and will effectively disrupt low-power CPS signals at ranges of up to 500m, according to Bendel!.
Such devices, says Rendell, could easily be used by those looking to steal or hijack goods vehicles from another vehicle, travelling close to their target. "In sectors where security and system integrity is important, operators are recognising that GPS on its own Is Insufficient," he warns.
