A Latvian government organisation overseeing electromagnetic spectrum have identified the Baltic Sea GNSS/GPS-jamming to originate from St Petersburg, Kaliningrad and Pskov, all Russian military heavy areas.
ESAKARI have notified intnl org's. h/t @signalseta
GPSJAM also shows GPS interference at this location on the India-Pakistan border on April 30 (h/t @lemonodor.bsky.social )

Good timing on this piece on global conflict and aviation infrastructure. GPS is woven into the fabric of aviation safety, and it is under widespread threat. www.vanityfair.com/news/story/i...

Amazing new GPS interference map and analysis tool from Stanford: rfi.stanford.edu This isn't an easy clone of GPSJAM like some others, this took tremendous work and pushes the state of the art.

GPS-jamming caused 4 near-collisions in Gulf of Finland last year. Ships made it because Finnish coast guard intervened.
The cause seem to be both external (the St Petersburg jammer et al) and endogenous (ships manipulating their own AIS)
It is general consensus that oil tanker collisions are bad.

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.
The Kaliningrad GPS/GNSS jammer is running on low power last two weeks, back to summer levels after a month at higher output.
The jammer in St Petersburg, covering Finland and Estonia might be tuned down a bit, but less clear trend.
More jammer stats in following posts.

Starting a few days ago there seems to be new potential GPS jamming activity around the border between North and South Korea. The last time I remember there being interference in this area was back in May. gpsjam.org?lat=37.39031...
I kinda made a pack for OSINT, flight tracking and event geolocations.
Work in progress.
