Earlier quoted context omitted.

The city has half a million residents and the oblast has a million residents. There's restaurants, museums, grocery stores, car dealerships, parks, zoo's, malls, stadiums, factories, train stations, an airport, ports etc etc. It's a real place.

I never said it wasn’t. Killeen, Texas is also a real place. How many people do you think don’t have at least a 2 degree connection to the US military? Do you think anyone there is going to think twice about going along with what the military is doing? Or could if they wanted too? And Killeen is far, far less isolated geographically.

It is like saying Detroit is military base because there are some military related buildings.

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.

Russia is constantly GPS jamming EU.

So funny seeing non-EU people and/or people friendly to Russia comment (not you)

Carry on!

That jamming near Kaliningrad must surely be impacting the Russian residents as well, right? Unless it is very carefully aimed which seems unlikely since it is also trying to cover a very large volume.

Russia does not care, nor does it care about its population.

Where are you from?

I ask because you have western privilege, like me, and assume our governments care about its people. Why I lucked out being born in Sweden, the more I learn about the world, the more I am convinced I lucked out ahahaha.

No one gives a fuck what russian residents are thinking about it. And if they start to talk about issues - police will quickly force everyone to shut up.

1) with the exception of probably a few pensioners (who also depend on gov’t funding), everyone in the area is dependent on the military. It’s a giant military base in the middle of nowhere. 2) anyone not military (and hence in on it), is a pensioner or the like and won’t give a shit about GPS. This is not a thriving urban metropolis or tourist location.

Why lie? It _is_ a tourist location, with > 2mln tourists annually (for their 1 mln permanent population). It also has quite a diverse economy, with Avtotor being a major car assembler (though not quite what it was pre-war), a fishing industry, amber mining, a TV manufacturer, &c. With a significant military presence, of course, but "giant military base in the middle of nowhere" is just ridiculous.

Crazy what the Russians destroyed... (you?)

Hey, old military installations (albeit ancient) are still a type of tourist attraction lol.

Most places in Russia are hunting and fishing locations too, hah.

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

Your local cellphone towers already provide a more accurate position beacon signal for GPS modules in most parts of the world. Additional RF beam-forming in G5+ systems also make it impractical for lamers to jam long-distances due to limited coherent signal propagation. Indeed, amateur Hams have caught Russian ships jamming/spoofing local port traffic several years before the various official overseas conflicts start…

Agreed about cellphone towers providing accurate position, but not with enough precision and highly dependent on the number of towers in the vicinity.

What i started building is for a highly unlikely scenario which is ; no internet + no GPS + no cell tower.
