Nato exercise ends GPS jamming over fears public safety could be at risk

DEFENCE chiefs have suspended the jamming of satellite positioning systems during a military training exercise after complaints it could compromise safety.

A Nato exercise called Joint Warrior 112 is taking place off the west coast involving military forces from 14 countries. As part of the operation Global Positioning System (GPS) services were jammed in a radius of 20 miles around warships.

GPS is used by fishing boats, coastguards and others at sea, as well as by hillwalkers and motorists.

There were also reports of failures of internet connectivity, mobile phone reception and satellite TV reception.

Politicians and council leaders have questioned the jamming exercise, with one MSP accusing the Ministry of Defence of wilfully compromising the safety of mariners in the north and west of Scotland.

An MoD spokesman yesterday said temporary jamming is routinely practised in military exercises and is an essential part of preparation for real-life operations.

Advance warning of when the jamming would take place was sent out last month to minimise the impact, he said.

He added: “However, in order to be absolutely clear that there are no genuine safety concerns to address, JTEPS (Joint Tactical Exercise Planning Staff) have suspended jamming for the remainder of exercise Joint Warrior 112.

“This will provide a period of time to reflect with all the relevant authorities about the conduct of GPS jamming and ensure that all parties are fully aware before the beginning of the next exercise which is scheduled for spring 2012.”

Angus Campbell, leader of Western Isles Council, said he will seek assurances from the MoD about future exercises.

He added: “Whilst the total effect of the jamming is unclear it is totally unacceptable if the MOD’s exercises are causing disruption to island communications networks.”
