GPS Jamming Trials 10-21 July 2011
Just received this from Ofcom and thought it would be interest to fellow Ppruners:
"The MoD has informed Ofcom of the following GPS jamming exercise:
Dates: Jamming will be conducted on a maximum of 3 week-days in the period 10-21 July 2011.Times: 0900 -1730 BST.
Location: Jamming aircraft will orbit at 10,000ft above mean sea-level (AMSL) along a 50nm flightpath on a heading of 270°T from Kirkwall, starting 10nm to the west of Kirkwall and ending 60nm to the west of Kirkwall
Possible areas affected: The GPS jamming is likely to affect civilian Standard Positioning Service (SPS) receivers over a large area. A minimum jammer to signal vulnerability of 30dB has been assumed for a civilian receiver. Signal theory suggests that a SPS civilian receiver should have approximately 32dB of jamming resistance.
Safety of Life Operations: Safety of life operations will take precedence over exercise activities at all times. To this end, the AWC is open to further discussion with any official recipient on the potential implications of this jamming exercise.
Contact point: During the exercise, any official recipient (or their delegated representative) and any member of the Emergency Services may terminate the jamming for safety reasons by calling the contact numbers below:
(1) Primary: Duty Controller Flying (TLT), RAF Kinloss - Tel: 01309 617857.
(2) Backup: Duty Controller Flying (TLT), RAF Lossiemouth - Tel: 01343 817428.
(3) Tertiary: Duty Air Surveillance Officer, National Air and Space Operations Centre – Tel: 01494 494812. "
