For the non-believers in GPS interference, here are some papers
written about a local GPS interference (or jamming) incident:

Spoiler:  The interference was caused by a broadcast TV antenna
mounted amplifier and I had nothing to do with finding the source.

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.
