GPS problems today?

Has anyone been using their GPS today - and noticed the signal dropping out every couple of minutes before returning? It's been happening on my Garmin since about 11:30 this morning (until about 14:30, when I switched it off), and the only other GPS I could find looked like it was doing the same.

It was happening very regularly, not dependant on what I was doing with the boat - so not like a loose wire/connection. Is Uncle Sam playing with the system (or delivering 'a message' to someone) today?!?

Hmm....

Never mind the Yanks - I saw a notice somewhere warning the MOD were doing some testing - can't remember when or where though.....

GPS jammers are quite cheap and effective these days - scary thought!!!

I also saw that but can't remember where...maybe they're blanking our memories too Codders.

Edit: just remembered. It was a navtex message. If it's still in the machine, I'll post the details.

Hi JW - thanks for that, I was wondering whether that sort of info was posted anywhere.

There was a short article on this in this months PBO...should be something on Admiralty Notice To Mariners that can be found on www.ukho.gov.uk
Normally the localised jamming trials only last a few hours so you should be back up an running shortly - from memory though, I thought the trials were taking place off the western isles....

The only GPS info messages I've got left in the navtex are that for Navarea 1, satellites 18 and 23 are 'normal conditions restored'.

Messing with our signals!

It seems to me like it might be time we all start wearing our tin-foil hats! It might be mysterious waves blocking GPS signals today, but tomorrow, it could be mind control!

Based on this image, those "in the know" are already doing this!
