Last 30 days jammed positions from aircraft around Helsinki.
1 minute resolution. Each dot a message filling criteria NIC 1-6, categories: A2, A3, A4, A5, A6. Fast as lightning.
Reference for a friend.
This is a more easily digested way of showing how bad GPS jamming in Finland is nowadays.
Since July about 7% of all flights in Finland are affected by electronic warfare from Russia destroying the planes ability to use GPS for navigation and time.

Russian research vessel AKADEMIK MSTISLAV KELDYSH is on her way home to Kaliningrad.
Just as in Feb 24 she slowed down from her more common 9-10 knots to 5 as she passed the wind, power and submarine infrastrucure dense south Baltic Sea.
Speaking against shenanigans is the fact that no NATO vessel paid any interest. AIS-caveats apply.
AKADEMIK MSTISLAV KELDYSH has managed some quite extensive miles of oceanography last year.
ERRATA: it should be "to 5-6 knots" not "5 knots" Sorry.
After a lull since end of July the Kaliningrad GPS-jammer was tuned to a high power, 24/7 mode at the start of this work week.
Presumably RU Baltic forces judge drone attacks to be more probable. Or they want to annoy western aviation extra this week.
The same effect, but illustrated by @lemonodor 's brilliant gpsjam.org
In the hiatus from July til now the jammer has been on only during nights, like clockwork. Visualized her by last months 5-min average percentage jammed signals.
