A few years ago, Putin hyped the Kinzhal hypersonic missile. Now electronic warfare is knocking it out of the sky with music and some bad directions.

    Is it okay to discuss this publicly? As funny as it I’d, I really don’t want Russia to get informed.

    “They think we make the attack on each receiver and as soon as one receiver attacks, they try to swap in another receiver and get a signal from another satellite. But when the missile enters the range of our system, we cover all types of receivers,” they said. “It’s physically impossible to connect with another satellite, but they think that it’s possible. That’s why they started with four receivers and right now it’s 16. I guess in the future we’ll see 24, but it’s pretty useless.”

    They’re just wasting so much resources and don’t even know what they’re doing. “Just keep putting more receivers, they can’t jam them all… can they?”

      that’s not even the most incompetent part imo

      the fact that the missile tries to change direction too quickly and just breaks itself apart from the aerodynamic pressure is crazy… it’s literally hobby robotics 101 to put limits on acceleration etc

        It’s just the life of each software dev: don’t need to account for this situation, because the target would never move by 10000kms within seconds. Plus, the buyer would never bring a failed unit back to ask for a refund, so why bother and spend more on development. Unless it’s a liquid fuel rocket, you wouldn’t be able to change Trust and speed once fired.

          but any software engineer knows sensors and inputs aren’t infallible … and neither is your code! you apply limits to account for anomalies, which should just be an expectation

      the theoretical reason for doing that is that if you have to split jamming power over broader frequency range, then for every n^2 times increase in bandwidth, here number of channels, range decreases n times. however gnss signals are so weak, it probably doesn’t matter, and if you’re adding extra power per channel, then it doesn’t apply

      now if missile detects that gnss is fucked with (signal too strong, wrong direction, physically impossible location), the correct thing to do would be to fallback to inertial navigation while accepting that accuracy decreases until gnss can be received again, if at all, and acted upon. theoretically speaking, it’s a matter of software update, better hardware also can help with that, so idk why would they release this. maybe there’s something that prevents this

        They probably released it because the situation has changed in a way that makes the information irrelevant, probably because it’s in the past, or knowing it could somehow damage the enemy. Any communication from a country at war should be treated as propaganda. Or, they know Russia will treat this as misinformation, so they are free to tell the truth.

          plenty of drone teams release geolocated videos day after they happen, but in this case i’ll guess that real sauce is classified top secret, that thing is outdated info and everyone is five steps ahead

          ahem

          triple the defense budget

    Night Watch uses a jamming system called Lima EW […] Once the song hits, Night Watch uses Lima to spoof a navigation signal to the missiles and make them think they’re in Lima, Peru.

    Those jerks are dooming those missiles with the worst possible fate: thinking they’re being sent to Peru

        For tourists, absolutely. For the average person born and grown there though? The government is unstable, poverty is rampant, and life standards are questionable at best

          Sure. I know lots of Peruvians but they’re mostly college educated. Inside Lima it’s pretty nice but in the villages it’s very poor.
