Well, if you ever tried to use a more powerful RF transmitter than your neighbor, you can overwhelm her signal, no need to "jam" with noise or mine for that matter.
I should have used a different word than jamming for the GPS map distortion, since it might imply that I was referring to sending random gibberish, so wikipedia to the rescue:
Now, knowing that DGPS (https://en.wikipedia.org/wiki/DGPS) is pretty common, I don't see where's the difficulty on sending a fake signal in the GHz range, more powerful than the weak one coming from the km high satellites.
Considering that some(most?) drones send their return video in the clear, I wouldn't be surprised if the GPS systems end up being not properly engineered to handle this scenario.
