Every system is a sensor if you hold it right.

Russia is running GPS-jamming machines in St Petersburg and Kaliningrad, affecting aviation and sometimes shipping around Baltic Sea.

Some of my most appreciated work has been localizing these machines in time, space and volume.

Here's a rundown of previous geo-work, reversed chronological order.

AIS-spoof-station WHISKEY 365 in Finland is offline.

It operated with a noteworthy 100% uptime for over a year. Oct 30 it started publishing anomalous data and caused a mass spoof event Nov 2.

Now offline since a few hours.

Guess: they were raided by FI authorities.

The AIS-receiver station responsible for the mass spoof event Nov 2 in Baltic Sea show anomalous data patterns during 8 more days but returned to normalcy Nov 9.

From a baseline of ~30 ships/h, for 8 days it reported 56-113 ships/h.

Speculation: Mass spoof might have been a mistake by attacker.

Swedish police and armed forces operated tonight at Landvetter, Gothenburg, Swedens second largest airport.

Drone(s?) were sighted around 17UTC and air traffic was put on hold with flights diverting.

Still no photos as far as I know :-/

Det kan ju inte vara något annat en rysk operation för att slå sönder den ukrainska järnvägen.

Nov 2 Russian subsea sabotage/intel vessel YANTAR was allegedly operating just off the Netherland coast, among a good chunk of European critical infrastructure.

The ship is specialized in subsea missions and ran by highly secretive GUGI, Main Directorate of Deep-Sea Research.

Today at 1109Z what looks like a mass spoof event of AIS-signal took place in central Baltic Sea.

In an area from approximately Bornholm to mid Gulf of Finland hundreds (thousands?) of new AIS-messages suddenly appeared. A large part of them military ships.

Russian ship YANTAR, specialized in underwater missions of sabotage/intelligence/engineering/research has made one ping in the Baltic Sea today. Last seen on AIS by Skagen, Denmark in Jan 2025

Operated by Main Directorate of Underwater Research (GUGI)

Likely a stunt, like 2024

Russian Navy’s landing ship, last seen outside German Lübeck a few days ago, weeks before of Danish island Langeland, now seen escorting gunrunner cargo ship SPARTA IV further north.

Starting to smell like a continuous armed presence in Danish straits.

I believe new.

HNLMS Johan de Witt (L801) and a German naval vessel are operating in the Irish Sea tonight, quite close to where Yantar hovered last November.

German SIGINT vessel OKER is further north, in the Firth of Clyde.

Danish Armed Forces tried to shoot down a drone that was intruding over an army base a few days into the Danish drone debacle a few weeks ago.

Several army sources and witnesses nearby told Radio4.dk

Topical “graph of truth” by Katja Berlin in Die Zeit —

Q.: Who takes an interest in German infrastructure?

Black column: German federal governments until a couple of years ago
Blue column: German federal governments as of a couple of years ago
Green column: Russia

Touché.

🚨Amazing:
🇳🇴 Norway’s drone detection system protecting Oslo Airport comes from 🇨🇳 Chinese company DJI Aeroscope, with system updates coming directly from DJI in China.

Unexpectedly that 🇨🇳 system was down for a full 19h from the evening of September 22nd, which is why the airport had to be closed.

The DGPS-stations of Skagen and Hammer Odde are unreliable, states 2 NAVTEX from today.

DGPS is supplementary to GPS and is used to correct.

As should be obvious from map these are strategic locations.

Previous instances have sometimes coincided with more ship jamming.

Is traffic picking up to/from Kaliningrad?

Four visits by the huge An-124:s in the last two weeks, with three visits the last three days.

First visits (in my book) from RA-73025 (Airbus A319-115), RF-86902 (Il-76MD), RA-82030 (An-124-100), RF-78794 (Il-76MD)

Sweden minister of defence Pål Jonsson attributes Baltic area GNSS/GPS jamming to Russia. I think a first?

In same news, not only ambulances on Öland but also cows get spoofed, both to the sea and to Kaliningrad.

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".

Russian air defence is keeping track of when Swedish signals intelligence aircraft S102B Korpen take off from Malmen, Sweden and Russian forces are notified and warned.

Other SIGINT aircraft does not seem to cause this warning to be sent.

Go Sweden!

The word ”illegal” is very prominent and frequent in the text.

I think new? The practices used to be described with only non-legal negative words.

”Illegal” implies a right to act and enforce. Maybe!
