    The jamming equipment could be the size of a briefcase; the received signal is below the noise floor.

    Or it could be one satellite already in the air beaming to a specific area. Or a constellation of satellites already in the air who handoff coverage of a specific area. Or a hack of an existing satellite constellation command and control channel to reprogram the transmitters to cover up GPS L band.

        I’m familiar with radio systems. You could absolutely put a 1 kW L-band jammer in a briefcase, with an effective radius of probably a couple of miles.

          Huh. I went to go look at that stuff and it’s definitely 2024. At any rate news articles made it clear that airports have dealt with GPS jamming for over a decade already and the FCC is pretty quick to send someone out with RDF equipment if it’s not a transient signal from a highway. Planes aren’t falling out of the sky so they’ve got a good idea of how to handle it already.
