Hello
Just read this following link in my local newspaper and thought I'd post it as it may disrupt some of our users coverage as a lot of new planes use the GPS for their ADSB I have been told. Probably a minority of users this time but interesting to keep an eye on in case it gets to be more widespread.

I guess this may also affect AIS reception in ShipTrax.
I think more users of Radarbox/SBS1 etc and AIS users have occasionally disruption from gps jammers on board trucks; truckdrivers use gps jammers to sabotage the track & trace system on board.
Also restaurants, cinemas use gps jammers.
