Not just jamming.  Spoofing and providing wrong

Note that this is (at least as reported) only affecting
the ubiquitous US civilian GPS signals which is what

There's also the encrypted US one used by the military,
and then there's the European ("Galileo") system,
the Russian, and also the Chinese options.
