Chat control skjuts åter på framtiden

EU-lagen ”Chat control” har strukits från justitieministrarnas dagordning, när de träffas i Bryssel på måndag och tisdag.

Vad är det för jäkla gubbkärring som kommit fram till att polisen inte skall strida mot fienden i krig?

Ni tror väl inte att polismän vore de första att dumpas i en källare i en svensk Bucha?

This is my explanation of the massive spoof event such as on June 14, it was simply a very good day for signal transmission. The transmitters in Kaliningrad are high power, under right condition, signals travel far beyond horizon, and all targets solve a location based on identical data

Ramon Zarate @oldsun.bsky.social · 4d

In short: The spoofers send fake satellite trajectories AND fake distances to these spoofed satellites. This is the only way two disparate receivers are going to solve positions at same place

No publications I have seen have dissected the content of a Pole-21 signal. I would very much like to see the transmitted ephemeris, how doppler frequencies are modulated and what time codes are sent. But I guess that is saved for some completely different eyes to read

and another point, we are playing games, solving puzzles with AIS and ads-b (I do it instead of sudokus). It is like looking at the world through binoculars turned backwards. The real organizations already know the truth based on sigint satellites such as Hawkeye360

If the ephemeris where correct and only fake distances are sent, the receivers will solve for fake locations RELATIVE to the true position of the satellite. But now all targets calculate positions vs same absolute location, the spoofed (fake) satellites

"The matched-code jamming signal did not have any navigation data, whereas the spoofing signals were modulated with fake navigation data. The false navigation data on the spoofing signals passed all parity and sync"

Ramon Zarate @oldsun.bsky.social · 4d

BROADCAST is the keyword here. The spoof signals are not tailored per target, regardless if receiver is in Gdansk, Bornholm or SE Gotland, they are spoofed to same location in Kaliningrad (during optimal atmospheric conditions). How can this be achieved? Note some passages in the articles

A thread to summarize my take on the GPS spoofing riddle, how do spoofing signals look like? How come faraway targets. from different locations teleport to same place (note, I am merely an armchair tech sigint hobby analyst). I have studied this from the comfort of my home.

But somehow the circle is closed if the president now gets in the debate on the Pentagon Papers. Maybe the want to investigate sources again, maybe start to wiretap political opponents?

The conclusion in the Pentagon Papers (the whole story leading up to Watergate) was that very early on it became apparent to decision makers that despite major military escalation, there was no road to decisive victory in Vietnam

Aaron Rupar @atrupar.com · 5d

Trump: "The problem with Vietnam, we, you know, we stopped fighting to win. We would've won easy. We would've won Afghanistan easy. We would've won every war easy. But we got politically correct. 'Oh, let's take it easy.' We're not politically correct anymore, just so you understand."

American production will not be cheaper than foreign+tariff. Cost will, at best, balance at foreign+tariff. American workers then received low paid jobs and high price products. Loose-loose

Ramon Zarate @oldsun.bsky.social · 5d

But we are merely guessing, looking at side effects. Would be interesting to find some observables to get more understanding

Ramon Zarate @oldsun.bsky.social · 5d

It is not only blasting signals, the ephemeris, frequencies (including Doppler effects) and pseudoranges (the clock signals) need to be carefully crafted to create the spoof locations

Ramon Zarate @oldsun.bsky.social · 5d

Ducting is a very seasonal effect, but one idea may be that they are targeting tropospheric scatter, firing fairly high energy signals at sky that will distribute at high ranges, ”raining down” on receivers

Ramon Zarate @oldsun.bsky.social · 5d

The details of how the jammers operate is still a mystery to me and there is still work to be done for a hobby enthusiast. Which satellites are spoofed? Do they transmit same ephemeris? How many transmitters are needed to modulate a circle? Capturing gnss signals would be high on wish list

Ambulances on south Sweden island Öland are reporting daily issues with their navigation systems, including spoofing and software that hangs.

These nowadays widespread sea level effects are puzzling. From known jammer locations one can not reach this far via line of sight. Space? Ship?
