GPS World Magazine:
<https://editions.mydigitalpublication.com/publication/?m=59713&l=1&p=18&view=issuelistBrowser&ver=html5>
Current edition (Aug 2024 Pg 30):
"Israeli Air Base Identified as Alleged Source of GPS Disruptions in
Mideast"

Argh.  Everyone seems to be practicing their GPS jamming.  If you skim
the pages, you might notice advertisements for GPS "simulators" and
locating equipment.  There are also some advertisements for non-GPS
inertial navigation equipment.

US, UK and Oakland airport show little GPS interference.  The middle
east, Ukraine and Russia show high levels of interference.
