Folks,
I have received the following announcement:
___________________________________________________
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.
