Most jamming in unintentional.  For example a TV news station sets up a
remote truck and aims the truck's microwave antenna right at your GPS
antenna.  Your GPS would be down but only for hours or a day or so.    Or
in some other case a transmitter on the same tower as your GPS fails in a
way that causes it jam everything nearby.  THese things happen.

There are about a quarter million cell towers in the US alone so these one
in a million events do happen frequenty.  But if you only own one GPS
receiver the changes of it happening even once is remote.
