The Baltic GPS Jammer is in Kaliningrad.

Fourth proof, refined dataset, second method.

Jammer seems to be stationary or atleast always on land.

Animated over time: radio horizons of the positions where planes first encounter the jammer.

Kaliningrad, Russia outlined.

For background on data see previous post or "method auonsson" in search.

We are using calculated radio horizon circles to triangulate the jammer.

Somewhere along the circle the jammer is. Where they most often intersect is the highest propability of location. Image
Obviously you have to imagine one of the little men a Russian electronic warfare machine and the other a high flying airliner.
This does not fit very well with the large concentration of circles east of Kaliningrad.

I think the explanation is the concentration of aircrafts in Suwalki gap and around Vilnius, ie very close, and that the jammer runs in lower power for that direction. Image
That makes my circles too big given that they are calculated on an assumption of max power.

We have previosly seen how the jammer can be directional and I think that is what is in play here.
Further along this line, the last week the Jammer has occassionally ran in a low power configutation only affecting planes in the immediate vicinity, mainly Gdansk.

This part is still preliminary data. Stay tuned. Image
Again, I want to encourage others to test my hypothesises. While I believe I am in very sound waters, more eyes are better.
Someone who could try a completely different method?
Someone who could do a proper stat testing of the results?

Data here:
Link for the lazy, most of what I written on the subject.

Lest anyone misunderstands, the circles are not the affected area.
This map shows all the points used for the center of these circles and the historic max reach of Baltic Jammer (polygon line) Image
In case anyone doubts that NATO knows exactly where, what, how and why this jammer is?

4 days ago Baltic States + UK wrote a letter interpreted as "Baltic Sea closing for shadow fleet".

No sanctioned tanker has arrived since (unusual*) but coming 24-36h the claim will get its first test with 5 sanctioned tankers inbound. Image
* It is unusual to not see daily sanctioned tanker arrive to Baltic Sea, usually a few each day.

But, the last 4 days lull ismight be explained by weather: Atlantic storms, low temperature and an increasingly frozen Gulf of Finland.
The ice is growing thicc around Russia's Baltic oil terminals.

Ice data outlets list a bunch of ice-breakers in service, but other sources have stated Russia lack capacity to keep the ice-sensitive rust-bucket tankers in play. Image

Underappreciated fact:

The paths and positions of the cable damages around New Years 2026 were to most of Estonia's internet backbone routes.

Had it fully succeeded/happened by accident (lol) Estonia would have been left with a crippled connectivity. Image

I just deleted a post where I had misread a press release.

5 cables have been damaged, but 3 of those from storm conditions. Image
I might not have been that wrong.

There is a SE-EE incident and a FI-EE incident.

The SE-FI is described as two breaks on the same cable last I read.

As per usual the details, allusions and contexts are vague in news and statements.
Updated map of cable breaks between Sweden and Estonia, based on press release from Estonian ministry for digital affairs.

The details are murky and partly incoherent and I have asked Swedish authorities for clarification.

Whats clear: there are several breaks on one cable. Image

Russian logistics ship ADLER is at anchor IN Sweden.

Possibly broken down. Usually runs heavy weapons to Russian bases in Africa / Middle East.

Was inspected by military aircraft 2h ago. Swedish Coast Guard just arrived to area.

Tnx @butafly over at the better site. Image
@butafly Coast Guard patrol is about to dock in Höganäs, port a few kms south.

Here they will likely pick up more staff for whatever they plan.

Guess: Nationella Insatsstyrkan or something similar. NI are police, but carry proper guns. Or, a cadre of really nitpicky bureaucrats =) Image
@butafly ADLER is very much IN Sweden, only 2 nautical miles from the coast.

Legally Sweden have much more legroom here then if she was outside our territory.

Let's see if we use it. Onboard one would likely find weapons or supplies headed for Libya/Syria or similar Russian base.

@pmolpmol lists three ships interesting as suspected drone carriers in last night attack on Copenhagen Airport.

In this thread, I will argue that Russian ship ASTROL 1 is an excellent fit.

Right time, right type, erratic track just before attack, highly suspicious background. Image
Article that led me down this rabbit hole, by @pmolpmol nyheder.tv2.dk/live/krimi/202…
ASTROL 1 is a largely flat cargo ship with hatches that likely would serve well as drone pads.

She is a similar model to SCANLARK, recently apprehended by German authorities on drone suspicions and to PORT OLYA 4, drone import ship on Iran trade. Sunk by Ukraine. Image

Copenhagen Airport is closed for operations because of drones in the air.

Northern Europes most busy airport. Image
