Folks, I have received the following....
NOTIFICATION OF GPS JAMMING EXERCISE: HEBRIDES RANGES, 8 to 12 April 2013
Dates. Between 8 and 12 April 13
Times. Between 10.00 to 12.00 GMT and 14.00 to 16.00 GMT daily.
Location of jammer. The jamming aircraft will fly a ground track based
on the Benbecula (BEN) VOR 275° radial. The aircraft track will extend
from 10nm west of the BEN VOR to 60nm west of the BEN VOR
Frequencies. 24MHz bands centred around 1227.60MHz and 1575.42MHz.
Jamming aircraft altitude. 3500ft Above Mean Sea Level (AMSL).
Affected areas. Interference prediction plots for a Civil GPS receiver
at 165, 3000, 10000 and 30000 ft AMSL
It is recognised that this trial will have some effects on local
operations but as always safety of life will take precedence over trials
activities. Therefore, in order to reduce these effects as much as
possible, the following measures will be carried out:
a. The jamming will only be transmitted in a westerly direction away
from the mainland.
b. Continuous jamming will be limited to 12 minutes maximum per run
with 5 minutes minimum between runs.
c. Both Benbecula Air Traffic Control and Stornoway Coastguard will be
informed each day as to whether jamming activity will be taking place
and when exercises are complete for the day.
I hope that is helpful.
