alt Hacker NewsGPS jamming is fairly detectable right? I wonder if we could create some crowd souced map of jammers. I think this kind of already exists as fairly course data but if a bunch of people installed fixed GPS sensors at home and wired them up to note every time their location lock is lost or moves. It could create a hyper detailed map of where the jammers are and track them moving in realtime.

They're easy to find, but not necessarily with stuff from off the shelf. Professionals with the right equipment though have no trouble locating them. The FCC is happy to hand out 5 and 6 digit fines for operating a GPS jammer and has fined retailers tens of millions for selling them.

Similar things already exist - although it's used for increasing GPS precision and detecting faulty satellites, moreso than detecting jamming, so the networks might not be dense enough to detect small areas of jamming.
For one state's example, see [1] - choose 'RINEX archives' if you want historical readings.
