#2I don’t see the assumption of the cause in the PDF (difficult to read on this tiny mobile device).
Could it be iron ore or something else affecting the magnetic fields? Does this happen elsewhere on earth?

#3I experienced a very odd GPS failures about a week later (September 24) in south-eastern Sweden. At one point I was driving for about an hour (in quite isolated areas - around https://www.google.com/maps/@58.0381615,16.2094966,13.37z) without my iphone being able to get a gps fix. It's never happened before, or since.
The phone was fixed to the car's front window with plenty of sight towards the sky. I rebooted the device twice but it didn't help.
Our natural instinct here is to blame the russians for these kinds of things. At this time our biggest military exercise since the 90s was taking place in this region, with a lot of US involvement: https://en.wikipedia.org/wiki/Aurora_17
(One random theory: the russians were trying out some kind of remote, localized target GPS jamming tech. The GPS outage stopped once I got closer to the largest city in the region (150k people).
Additional rationale: If they unleashed GPS jamming signals that made hundreds of thousands of people lose GPS it would probably have made news. By localizing it to just affecting a couple of hundred people in isolated areas they would avoid that kind of mess.)

Seems unlikely to be a natural phenomenon, considering it's never been noticed before.
Could be the Russians are up to something? Jamming GPS signals would be a significant strategic advantage in war time.

The two-sentence "Result of the Check" section ends with "and the strength increased the closer to the Russian helicopter wing".
As professionals, they state the observations and facts and don't cross into the realm of speculation.

But after a few tens of meters in the air we see a noise signal. [...] The noise signal is on GPS L1 (1575.42 MHz) with 1 MHz bandwidth, see Figure 3-5.
So the signal is jammed by something sending a noise signal around the L1 frequency, whether intentionally or not.

They are doing this in bigger Russian cities. GPSes often doesn't work in downtown Moscow or St. Petersburg. There's plenty of information available on the internet about this. Also, they have their own positioning system, that is also available worldwide - Glonass

Care to link to any of that information?

#10There was massive solar flare activity in September which may (or may not) have something to do with this.
