Limited GPS jamming will take place this week as HMS Queen Elizabeth visits Glen Mallen. 

Between 5am on Monday March 14 to 11:59pm on March 20, airspace restrictions and limited GPS jamming will be in operation across the west of Scotland. 

These measures are standard for carrier movements and are in operation to keep the ship and its crew safe. 

Airspace restrictions will cover Greenock and the surrounding area, whilst jamming will take place over a larger area including Largs, Cumbrae, and down to Irvine.
