UK : GPS Satellite Jamming exercise July 2011

Just the MoD checking that they can confuse and confuddle at will if need be.

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.

For those interested, you can sign up with OFCOM for updated lists of such exercises here.

I've still got my compass and map, so assuming that magnetic north stays roughly put where it is, I'll be ok...

Any mention of what this excersise is for?

I can't think of a reason myself other than to test for a future GPS blackout operation and using citizens as guinea pigs.

No mention of any reason, just what it states in that comment.

I've never really looked into the whole GPS jamming malarkey, my attention was drawn to it from a link I was directed to by a friend of mine who knows I'm a bit of a radio geek.

I wonder how often these exercises are carried out on both sides of the pond?

why hasn't this been done sooner?

switch it on and then arrest anyone looking lost! haha

locals know their way back and forth, the right software could store these routes and flag up any out of the ordinary trips.
