GPS being jammed in Cumbria

The Ministry of Defence has a firing range at Eskmeals,ive worked near there on the odd occasion in ravenglass,and the locals say they block the gps from time to time when doing tests,i dont know if this is true,but thats what i heard.
 
You could be experiencing major interference. If there's another broadcasting antenna using the same frequency band (or a close band) then it will block out the GPS signal.

It's most likely illegal since the FCC would have very strict rules about any device using that band.

Thanks for that, it's a new one on me.

Following the Ofcom connection, I found this:
The Ministry of Defence conduct occasional tests on military systems which may result in some loss of service to civilian users of the Global Positioning System (GPS) including in-car navigation devices and networks which rely on GPS signals. Ofcom seeks to provide citizens and consumers with information about possible interruptions to these services. It must be emphasised that this notification process only warns of future jamming exercises that are brought to the notice of Ofcom and may not cover all jamming exercises. It cannot be assumed that any loss of service is due to jamming exercises.

It appears that this sort of GPS jamming happens quite frequently and without much publicity. I wonder how long it has been going on for :confused:

The FCC is an American agency with no jurisdiction within the UK, or anywhere outside the US for that matter.
In the UK Ofcom is responsible for licensing and protecting the use of the radio spectrum.

According to BBC online:
The illegal use of Global Positioning System (GPS) jammers in the UK has been revealed in a groundbreaking study.

GPS jammers are believed to be mostly used by people driving vehicles fitted with tracking devices in order to mask their whereabouts. (LINK)

Oh, I thought you were talking about something actually related to the thread.

Sorry about that, I forgot who I was talking to for a second :)
 
It seems a bit of a fault in car security terms if a GPS tracker can be blocked by a simple jammer or are car security trackers more sophisticated somehow?

Also, good job Werewolf.
 
Must be a problem for the local emergency services who use gps.

Reading this thread, reminds of the lorry driver I spoke to year before last at Keele services M6, he had small grey box (about 4"x2"x 1.5") which he picked up by his trailer, & presumed it had fallen off it.

There was remains of glue on the base, I suggested he give it to the police & get them to contact his boss about it.

I do wonder whether it was a gps blocker?
