There are sooo many GPS interference exercises NOTAMed! Here's an animation I made of GPS interference NOTAMS in effect on any given day in the U.S. from 2022 to 2023: https://x.com/lemonodor/status/1722275349554487750

And they affect thousands of aircraft--Here's a thread where I analyze an earlier exercise at White Sands, called NAVFEST: https://bsky.app/profile/lemonodor.bsky.social/post/3ml7afb2...

  * Approximately 4000 aircraft experienced significant GPS interference
  * 90% of which were commercial jets
  * The military appears to have been jamming outside the posted NOTAM hours
    2750 aircraft jammed during the window, 1250 jammed outside the window.
  * Used to be called JAMFEST but "the Joint Spectrum Center became
    uncomfortable with the idea of associating its RFAs with events with the
    word 'jam' in their names."
