'High' Probability of Russian Attacks On Starlink In Ukraine, Says Musk (arstechnica.com) 108

SpaceX CEO Elon Musk yesterday warned that Starlink user terminals in Ukraine could be targeted by Russia and advised users to take precautions. Ars Technica reports: "Important warning: Starlink is the only non-Russian communications system still working in some parts of Ukraine, so probability of being targeted is high. Please use with caution," Musk tweeted. When asked for specific advice, Musk said people in Ukraine should turn Starlink on only when it's needed, place the antenna "as far away from people as possible," and "place light camouflage over [the] antenna to avoid visual detection." A thin layer of spray paint would work if there are no metal particles in the paint, he wrote. One Twitter user asked Musk if Starlink could face a cyberattack from Russia similar to the one that affected Viasat satellite service. Musk responded, "Almost all Viasat Ukraine user terminals were rendered permanently unusable by a Russian cyberattack on day of invasion, so... yes."

As previously reported, Ukraine Vice Prime Minister Mykhailo Fedorov asked Musk to activate Starlink in Ukraine shortly after Russia's invasion of the country disrupted Internet service. Musk responded in the affirmative, and two days later, Fedorov tweeted a photo of a truck full of newly arrived Starlink terminals. It's not clear exactly how many Starlink terminals are available in Ukraine, but Fedorov tweeted to Musk, "We will keep you posted as we roll out more Starlinks across the country."
In another tweet, he said, "SpaceX reprioritized to cyber defense and overcoming signal jamming. Will cause slight delays in Starship and Starlink V2."

    Just run a very long cable to the terminal. If putin's forces triangulate and bomb, they will waste arms shelling and empty field. Actually they will destroy that antenna, but it is a much more acceptable loss.

    Or do one better, run a wireless repeater at that point, and use a directional antenna at your own location. Slow internet is better than no internet.

      As an aside, I keep marvelling as a ham radio guy how many people, including other hams, do not comprehend the concept of radio silence. It is basic strategy and tactics for over a century! Low Probability of Detection / Intercept is the extension of this that a lot of money & thinking has been poured into over the decades (and isn't just for radar).

      Spread Spectrum was one of the first tech to try to send a signal without being spotted, but as much of today's broad-band tech actually requires it to wo

      • I wonder if SpaceX couldn't implement for Ukraine some kind of LPI mode in the dish firmware. Like, sacrifice uplink bandwidth for decreased probability of detection? Admittedly this is where a phased array fails. A parabolic dish would suppress side emissions much better.

          I wonder if SpaceX couldn't implement for Ukraine some kind of LPI mode in the dish firmware.

          They already did exactly that. There's a new low-power mode that also allows the dish to be powered from a car lighter's socket. Prior to that update the startup and operating power use usually tripped most car lighter fuses.

          • Prior to that update the startup and operating power use usually tripped most car lighter fuses.

            Most of them are at 15A, so let's just call it 12V and say over 180W. Yowza. IIRC the final design wound up with a cheap phased array with one axis of motor steering so most of that has to be RF...

            • by Cyberax ( 705495 )
              Yep. Right now it draws about 150W on startup and during the initial positioning (which is enough to trip my car's fuse). It then goes down to about 100W. The emitted RF power is 4.03W according to the FCC certification documents.
              • Thanks for the numbers.

                Cigarette lighter socket circuits are typically pathetic in every way. Might be not just more convenient but actually wise to run a dedicated circuit. XT30 or Anderson Powerpole connectors would be cheap and way better than that lighter socket crap, too.

          I have defeated beam based radio direction finding before by modulating the power with low frequency flicker noise, but I suspect that an anti-radiation missile would be too sophisticated to be deceived by that.

          Other methods for LPI require greater changes which the existing hardware is unlikely to support like coherent detection of a much wider spread spectrum signal.

      • by Rei ( 128717 )

        They can, but if you're throwing a $300k anti-radiation missile against a $500 Starlink terminal, that's probably not a winning strategy in the long term.

    • by Jzanu ( 668651 )
      Your proposal is actually a very good one. Historically many German army battlefield communications during war were conducted by cables manually laid in forested and overgrown regions. While these could be disrupted by area bombing, the only really effective countermeasure was for allied soldiers to track the communications group troop movements and use infantry to cut the lines. Of course interception was more useful in many cases but aside from that, the technique provided reliable communications that co
    • If you can run wireless repeaters, why not just use the wireless repeaters to deliver the Internet along with some combination of fiber-optic cables and plain old microwave to connect to the outside world or the still fairly conflict-free parts of the country? Does the Ukraine have a difficult topography that makes satellite-based systems an attractive option?

    There are a few things people could do to camouflage their antennas: a few light coats of paint, patterned contact paper, shelf paper, lightweight fabric, place it next to a few other round objects like garbage can lids, set a pizza box over it, pretty much anything with a low moisture content to help it blend it.

    Musk also wrote that mobile roaming [has been] enabled, so [the] phased array antenna can maintain signal while on [a] moving vehicle. It sounds like keeping these mounted on a mobile platform would also keep them from being destroyed as easily, but they would be a little harder to disguise. Perhaps in the back of a truck with a thin tarp over the back would keep them out of sight.

    • Musk also wrote that mobile roaming [has been] enabled, so [the] phased array antenna can maintain signal while on [a] moving vehicle.

      If he'd do that here in the US, I'd sign up immediately. That would be a killer feature.

        Apparently Russia doesn't have a lot of missiles anymore, so it's indeed likely that they would get a visual confirmation first.

        • Yea, I see a lot of artillery but not a lot of missiles. For a while I thought they were saving those for backup but then thought as fast as he is pushing his forces in the country, he might just not HAVE any cruse missiles. I know he doesn't have airpsace control yet after all this time, so does that mean he doesn't have any anti air either?

        If Russia decided not to use an anti-radiation missile after detecting it, then visual identification would be desired before further action, and I sure would not want to be on the receiving end of a raid intended to capture prisoners.

      Yeah, "pedo guy" was the moment I fell out of geek love with Musk. But let's not pretend that this doesn't completely validate the concept of Starlink providing alternate communications in crisis situations, or that it's not a good thing. Would he have done it if it wasn't good PR? Maybe, maybe not. Probably not, even. But let's not shit on him for it. There will surely be some good reason to do so soon enough.

            Local oscillator leakage is only reduced to the point where it meets FCC part 15 requirements or similar, but the level is still too low to track from any significant distance. A couple of times during transmitter hunts, I tracked the transmitter's local oscillator while it was in receive mode so that I did not have to wait for the transmitter to come back on, but that was at 100s of yards at most with a gain antenna. Once the hiders of the transmitters figured out what I was doing, it became routine to c

  • A parabolic dish will have far less lateral emission to begin with, but you could put the dish in a barrel too and line the sides with microwave absorber for relatively little cost. That's going to be a very weak source when you aren't in the line of sight of the dish.

    • You still would have to setup the dish though to maintain line of sight with the satellite though, or am I missing something?

      • As I understand it, since Starlink satellites are in a low orbit and basically whizzing around all over the place (in aggregate, especially compared to geosync), you can just point the antenna kinda anywhere vaguely upwards.

        In theory, as long as there's open sky to point at, there will always be at least 1 or 2 satellites within the antenna's "field of view" and within communications range, simply due to how many there are/will be in orbit. Since they're supposed to have a really good hand-off protocol as

      • Yes, but a geostationary satellite is stationary. The dish only needs a very small stationary view cone. You can pull tricks to minimize scattering in other directions which would be infeasible with a phased array aiming antenna for LEO satellites, which needs to see far more of the sky.

        A phased array might not scatter too much from an efficiency point of view, but a couple percent is more than enough for an adversarial detector even if it's irrelevant for efficiency.

    • Its a phased array. Lateral spread is minimal when you steer the beams... https://en.wikipedia.org/wiki/... [wikipedia.org]

      the receiver needs a wide horizon to pick up and drop satellites as the cross the sky

      it is the same reason that satellite phones suck on canyons and large cities

    It is amazing to me how many postings on this topic there are without mentioning the possibility of decoys. There are a lot of cheap devices you can program to look like an intermittent Starlink base station to a radiation seeking finder (either handheld or on a missile) and they can be battery powered. You can scatter thousands around your operating area.

    Then it is just a matter of updating the software to keep ahead of the enemy's detection improvements. But the real base stations will be safe enough as long as they aren't high duty cycle.
