The theory that they broadcast communication on a band near GPS in order to discourage jamming of their early warning system sounds likely. Flexing the ability to jam GPS is pointless, since it's obvious that any state actor who has military satellites in orbit has considered this option or have the capability already. Therefore, the disruptions must either be regular tests of the capability, or just actual communication. Right?
> The theory that they broadcast communication on a band near GPS in order to discourage jamming of their early warning system sounds likely.
Is it? If it is an early warning system, could it be jammed briefly so it would fail to warn, couldn't it? It will be a global disruption of GPS, but a brief one and I'm sure people wouldn't be concerned of it due to other news.
> Flexing the ability to jam GPS is pointless
Do you believe that cutting sea cables is a sensible action? Or sending drones to neighbors? It is what they call "hybrid asymmetric warfare", I'm not sure how it is supposed to work, but presumably it may let them take over the world or something.
Probably they just strive to normalize deviations, to boil frog slowly. When people become used to some stupid actions they widen their repertoire, until everything short of tanks crossing the borders became just normal news noise nobody reads twice.
There is definitely value in having a demonstrated as opposed a simply supposed capability, though. And actions that are 'almost-certainly-but-not-completely-provably-us' is very much something Russia likes to do.
(One question I would have about the comms theory is whether the amount of power being used would be reasonable for that use-case. Jamming tends to be much higher power than just communicating, but also GNSS signals are very low bandwidth as comms channels go)

Forget "state actors", truck drivers have taken out entire airports with GPS jammers:
The US still has a fairly robust network of VOR's / VOR with DME / VORTAC stations. Good for navigation, but there's no timing component, beyond what's inherent in how they operate.
Admittedly, that'll never be of use outside aviation as its line-of-sight only. But if the sun threw a Carrington event (or worse) at us, I think a lot of western aviation could carry on.

I'm aware of the FAA's MON, Minimum Operating Network.
Exactly: that doesn't help boats. Or people in cars. Or farmers:
yeah, I have to admit I was commenting on possibilities here without having gone into the article yet -- having now looked for real, I agree that the disruptions don't seem very useful for actual jamming and repeatedly like this for years across satellites and bands in this specific way doesn't make sense for some mistaken targeting either.
The video did not settle on the jamming of von der Leyen plane on approach to Plovdiv, but AFAIR it was a (likely unintentional) lie.
Never acknowledged by von der Leyen nor by her press secretary because it exposed the lack of basic world knowledge around von der Leyen and her office.
TLDR: Neither von den Leyen nor her office knew about ADB-S nor about the multiple services that collect ADB-S broadcasts and republish, and there was none around who could stop them from announcing an embarrassing lie.
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.
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.
>must surely be impacting the Russian residents as well, right?
They don't give a fuck.
Was watching a youtube video by a russian the other day talking about war & sanction impact and things like ride sharing apps literally say on screen the location is going to be wrong and to select pickup spot manually. It's just assumed to be fucked as a given even at an app development level
Jamming in general will affect everything using those frequencies (and potentially more besides) in a given area, so if you're using it you're weighing up the effects it'll have on your stuff as well. (early in the current Ukrainian invasion, reportedly Russian electronic warfare units were screwing up their own side more than the Ukrainians)
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.
Doesn't sound like you have actually been there. Military is a major employer, but in a territory inhabited since 1944 there are generations of people born there who didn't see a reason to live, the same foreign gastarbeiter as in any Russian city, etc. I.e plenty of ordinary people who could be inconvenienced.
>I wonder if we can do something now that we know the source.
Russia signed the 1967 Outer Space Treaty (OST) in 1967, this may be a treaty violation of this or other treaties, something like that or retaliation regarding it may be possible.
You can hack the satellite, or use other electronic warfare options to jam or interfere with it's operations.
You can shoot it down with a missile.
The X-37B is in space right now and interfering with space assets is a pretty obvious possibility for why it exists at all, but it's secret so nobody says these things.
If you start shooting down stuff in orbit, it'll invite retaliation, but even without retaliation there's a huge risk of a Kessler syndrome (especially with all the stuff that SpaceX has put into orbit in recent years).
> especially with all the stuff that SpaceX has put into orbit in recent years
I've heard this repeated a lot but I've never seen anyone do the maths. StarLink satellites are all in very low orbits, so intuitively it seems like most debris from a collision would just end up deorbiting.
No, Kessler syndrome is pretty unlikely in this case. All of the guilty satellites are in Molniya orbits. Debris from destroying them would not greatly effect geosynchronous orbit or the low earth orbits used by Starlink.
I've thought about this before - do you actually need to "shoot it down" (make it explode)? What if you just nudge it a little and either make it spin or change its orbit? If your missile can reach the satellite then these seem like things that should be possible, no?
Depends, if you nudge it only a little, its own onboard stabilizers / thrusters should be able to correct it. It'd have to be more than its own systems can correct for.
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.
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 started. Not sure if it is government sponsored, or just various smuggling schemes like some ships spamming China harbors. =3
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."
> Note that Cosmos 2546 was launched in May 2020 and so cannot be responsible for the interference events that occurred in 2019. Moreover, Cosmos 2546 was not over Europe during some interference events after May 2020. But during all events on the 75 days shown in Table 1 there was at least one EKS satellite above a 35∘ elevation angle with respect to every reference station that observed the interference. Thus, it is highly probable that the EKS constellation is collectively responsible for the wide-area transient GNSS interference events noted since 2019.

It doesn't help those that use GNSS for precise timing (TCXOes can only 'free run' for a finite amount of time before drift compounds 'too much').

Obviously a bad idea, but frying it with some sort of high powered electromagnetic pulse would seem the smartest option with plausible deniability.
I wonder if the US already has such weapons in orbit.
