‘Starlink can obviously offer far more robust positioning than GPS, as it will have ~1000X more satellites over time. Not all will have line of sight to users, but still >10X GPS & far stronger signal. Just not today’s problem.’

These are scientific stations, capturing raw gnss data, used for capturing mapping, continental drift etc. What's good is that raw satellite signals are captured and made publicly available.
I revisited June 14, known noisy day, with new take on resolvers. These are Rinex data from stations Hoburgen, Bornholm, Gdansk and Braniewo. Note the shooting lines, these are valid solutions, but diverging from station

What we see here is signal strength per satellite over time as it is panning over the sky. The disruption is when the spoofer takes over, we do not see the characteristic increase/decrease when satellite passes, the spoof signal is irregular

Geolocation challenge
Russians are publishing footage of what they claim is the flight of a FP-5 Flamingo missile during an attack on Moscow on the night of October 27.

I was having a look at traffic gps data for central Moscow. It is really crazy, wherever you go, you will be teleported. But here are some highlighted hotspots. Red means high jam ratio

GPS jamming situation in central Moscow. Holy mother of God

🔥🔥On the Mi-24 combat helicopter "Shahed Hunter," there is no more space left for marking down the shot-down russian drones, and the crew has started combining the badges.

The aircraft has shot down over 120 (‼️) enemy UAVs.

This is only 25km from where an Estonian security service officer was kidnapped in 2014 by the FSB in a raid across the border and jailed in Lefortovo prison
Estonia has closed off a road/border passing through Russia after larger than usual groups of troops have been spotted.

Comment: I am hard pressed to find any insignia on those filmed and SE news claims "little green men".

We see more reports of civil infrastructure in SE Sweden impact of the gps jamming, ambulances, farmers, cattle gps tracking. Strava is impacted. Have not seen anything on the robotic lawn movers gone missing, but I guess it is coming

Not sure if this is anecdotal, or a trend with increased range
