frank-123 Posted March 17, 2011 Report Posted March 17, 2011 had this email sent from offcom today 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. ...........................................................................
OLDYELLOW Posted March 17, 2011 Report Posted March 17, 2011 Be interesting to see how this effects the birds during that period , also the great digital change over will be happening in August so wonder how that will effect the birds
frank-123 Posted March 18, 2011 Author Report Posted March 18, 2011 another email today The MoD has informed Ofcom of the following GPS jamming exercise: Dates: 19 – 26 May 2011. Times: limited periods between 0700z 19 May to 100z 2 May 2011. Location: The ground based radar jamming events will take place in the SW approaches against the remote radar head at Portreath 21-22 May, undertaken by F-18 Growler aircraft. Additionally there will be radar jamming against deployed targets in South West Wales throughout the period 19-26 May. Communications and airborne radar jamming will take place throughout the same period on the East Coast with aircraft operating within the North Sea Military Danger Areas. Communications and maritime unit radar jamming will take place in the SW approaches and Bristol Channel. Falcon aircraft will operate from Sea Level to FL240 unless jamming AEW aircraft where they may operate above FL245. Contact: G R Pickett Sqn Ldr SO2 Air C2 JTEPS Mil 9360 58786 Civ 01923 958786 Note: Safety of life operations will take precedence over exercise activities at all times.
