sippeangelo | on: Tracing a powerful GNSS interference source over Europe
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?

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.

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:

People like the Resilient Navigation and Timing Foundation have been trying for years to get some kind of GNSS backup accepted:

China has certainly put their money into resiliency (both navigation and timing):

Some folks are certainly cluing in: South Korea has (e)Loran and the UK and France are joining up with them:

Unless the actor happens to be a state that puts a great deal of emphasis on flexing & appearances regardless of how pointless it is

Why these capabilities, if they exist, were not used to send Iranian drones to a wrong target? Maybe because they do not exist. Israel definitely would be happy if thousands of drones were rerouted to a neighbour country or into the sea.

Even if that's for communication, repurposing it for mass jamming shouldn't be that hard. It already has this effect. Unless it's low power satellites that wouldn't be able to sustain radio signal in anything longer than short bursts.

Or actual jamming mistargeted for some reason, or used because it was deemed necessary.

No, Russia does these "tests" all the time to see and gauge the reactions. Ex flying just a bit into EU airspace.
