I don't think this is really news. Anyone with an SDR good enough could easy replicate and alter GPS signals. Since the satellites are so far away, spoofing and jamming are simple affairs. You could affect GPS for miles with something you can carry in your pocket. You can see a crude form of this around tall buildings. Multipath from large structures is enough to "spoof" GPS by hundreds of meters.
