Is jamming starlink possible in a large area? Both the satellite and the user terminal uses phased array antenna so it has nulling capability, frequency hopping and not to mention thousands of satellites in orbit connected by lasers.
I think it's not practical. If russia hasn't been able to done it for last fours years then it's just not worth it.
Well nulling is a bitch indeed especially when you are out off mainlobe. However there's finite degree of freedom of this type of antenna. Starlink has like thousands of physical elements but the digital nulling is lower maybe dozens or probably hundreds. So if you can attack the satellite with enough nodes you could probably blind a satellite though there still would be more satellite avaliable in the area. Another option is to do a pseudo random fast switching between multiple nodes at different postion. That way you could probably exhaust its computing power for performing adaptive nulling.
>>17010341It would probably cause public outcry if Russia did do it and go against keeping quiet and gaining some land on the side while everyone is thinking about space colonization?
>>17010324>so obsessed with Elon you're daydreaming about being a supervillaingo outside and take a walk lil bro
>>17010421Why is this man potato shaped?
>>17010428You may not like it but this is what peak performance looks like.
>>17010324Veritasium reported GPS was momentarily tampered with by linked Russian satellites, possibly as a test. They could set up jamming on the same network?
>>17010433So we should all be potatomaxxing
Living a rich day and having a drink with Elon would be better than watching it at the movies.
>>17010324>>17010434Iran was able to jam the network through GPS and extremely powerful Ku frequency jammers.As a practical matter however Ku jamming is a last resort and is extremely short range requiring multiple coordinated jamming devices for effective coverage. This was deployed after Iran had already physically located most of the terminals used for protests.GPS is piss easy to interrupt but the Starlink satellites to my knowledge can be used to send their own time clock and position. Essentially replacing GPS as a means for locating the position of a terminal.
>>17010421I mean countries like china also doing it. This kinda mega constellation are threat to every major powers.
>>17010444Yeah it uses something called PNT. Though I don't know if it has any limitations for fast moving terminals.
>>17010444The chinese proposed a idea about using thousands of HAPS to jam dush dowlink. Although I don't know if that's scalable.
>>17010444>>17010488Also they're experimenting with satellite hpm weapons but that's too overkill in our discussion. If we use less powerful short time jammer just enough to disconnect entire satellites uplink for few seconds it could probably knock each dish for dozens of second or minutes.
Bump
>>17010444>GPS is piss easy to interruptTrue, the radiated power is tiny.>but the Starlink satellites to my knowledge can be used to send their own time clock and position.Do they have atomic clocks onboard? I did a quick search but found nothing. Iridium satellites are being tested for navigation, so I guess they have upgraded clocks, and transmitting on a different band (1.6 GHz, near existing GPS bands) that offers a fallback position in case of jamming.>Essentially replacing GPS as a means for locating the position of a terminal.These networks now have so many satellites you can do multilateration and determine the exact position of any and all terminals unless you apply some serious tricks. And for all we know, they might already track more than just terminals.
>>17010713I understand for stationary terminals it can work. Just scan through sky and peak up a satellite and rest of the near satellite positions can easily obtained from orbital map. But what about fast moving terminals?
>>17010726pick*
>>17010726Multilateration gives you one point at a time and speed matters little. You can use GPS from fast aircrafts. Satellites can also determine the doppler shift and determnine the instant velocity vector.
>>17010324Apparently there are jamming attacks against it, but I have no technical knowledge about it.I've also read a few random comments about an attack that supposedly can locate the user terminal...>>17010421>do obsessed with Elon, he takes everything against one of his companies as an attack against the man himself, and defend him for free>subtly, shamelessly implies that the OP has mental issuesLOL, LMAO even.
>>17010324reddit fan fiction
>>17010434Starlink has GPS independent proximity detector as well(for the right people). So its not dependent on GPS if push comes to shove.
>>17011609>muh right people They recently blocked the API that people like ship navigator used in gps jammed area.
Well nulling isn't absolute. It has a depth limit. I don't know how much EIRP it takes to overcome it though.
>>17011746Not the right people
>>17011609>proximity detectorSure? I know Starlink had an independent PNT facility that was recently turned off, but that is different from a "proximity detector".
>>17011818They only disabled it for the normal users, military that has access runs the full advanced capability on all fronts
>>17010324Can't you just beat its nulling by using multiple jammer node?
>>17010324Starlink
Sucks
