Russian EW forces has moved or retuned the St Petersburg jammer.
I believe it is repositioned to better protect Kronstadt naval base and Primorsk oil export port.
As a side effect or also desired effect it is affecting a larger area north over Finland, since early July. 🧵

Positioning is done by counting where the highest density of radio horizons of jammed planes intersect.
Resulting area is just west of St Petersburg. An area housing both a main naval base and hugely important oil export facilities.

A few months back data pointed to the jammer being housed southwest of St Petersburg, close to Narva, Estonia.

Same data as above, but other background map.

This illustrates the area used for analysis and each red dot is one of the 10'954 aircraft messages used.
I filter for only the first message per 3 hour period per aircraft individual, to avoid having chatty aircraft get to much weight. The west hot zone is an artefact.

Next up I will quantify how this new reality has affected aviation over Finland. It is drastic increases. Stay tuned!
Earlier localization of the Kaliningrad jammer.

Many thanks to @live_airplanes for data and @PajalaJussi for intersection analysis code.
Disclaimer: this method has an unknown precision. I am confident on country, but dont believe it is precise enough to pinpoint exact position of the responsible electronic warfare machine.
