Nice talk about the project by the maker:

Very interesting, because it is not just the usual gps talk
At the end he casually mentions so many things that he could also talk about, including that apparently the encryption on GLONASS military signals was already hacked, and that many parts of the mil-spec GPS are "securiy through obscurity"... Is this true? If so, where can I find more reading material about this? It was my understanding that the P(Y) code in GPS is encrypted using (basically) a OTP, and not based on obscurity at all? Doesn't GLONASS use a similar system?
Could you please comment on this:

How does he track the jamming?
How do the russian jam?
How could they ever jam up such a large swath?
Does that even have a discernible effect on modern GPS receivers in smart phones?
Surely it doesn’t effect military systems, they would anticipate jamming, right?
Sometimes the interference seen on those maps does affect phones, sometimes it doesn't.
Coincidentally there's a huge region of GPS (at least) interference this week over the New Mexico area, from a military test. My guess is that people on the ground won't be affected, unless maybe they're very close to White Sands Missile Range between 18:30 and 22:30 GMT.
