Tracing a powerful GNSS interference source over Europe

Interesting to see that they are able to identify the specific satellite. I wonder if we can do something now that we know the source.

Working on construction projects on the Romanian coastline (just South of Ukraine) and on the Polish continental waters (just West of Kaliningrad) we experienced jamming on a daily basis.

It's been known that Russia does GPS interference near their Western border and the Baltic down to Ukraine for several years now. It's something airline pilots prepare for now, and expect.

Not sure why this is being couched as novel or surprising.

I do not see any discussion of the power required for such wide-area jamming. Even as the useful GPS signal is quite weak at the ground level, this satellite would require power in kW range, right?

TLDR (conclusion from the paper): "By a combination of these techniques the satellite Cosmos 2546 (NORAD ID 45608) was identified with high confidence as one source of the interference. Further analysis pointed to the Russian Edinaya Kosmicheskaya Sistema, an early warning constellation to which Cosmos 2546 belongs, as collectively responsible for the wide-area transient interference causing GNSS degradation across Europe since 2019."

Hmm - the timing is uncanny that only 2 days ago I started building a dead reckoning system.

There's a live map too: https://gpsjam.org

Being engaged to warfare with Russia and being jammed in response. So weird.

tl;dr - it was Russian satellites

You can likely bet that Space X with their thousands of sats deployed in space already has among them a few hundred stealth US military sats strategically placed and ready for the command to deal with the few Russky sats causing these problems ... think our Space Force.

This thread seems an intended call for all NAFO warriors to quickly gather with anti Russian speech. Fair enough, there's a war, GPS jamming is to be expected. Maybe annoying for some, but a need for others. Hope the war to not escalate further, it will be more than GPS inconvenience.
