![]() There will be plenty of stories told after the war, but for the time being, how Ukraine is beating drone jamming is very much a secret weapon. Other sources mention rumors of Ukrainian projects to counter jamming, but everyone I contacted preferred not to give away anything at this stage. ![]() It might even be targeted by a drone which homes in on the jamming signal itself, like a low-cost version of a HARM missile. This makes it easy to hit with artillery or mortar fire. Blasting out a lot of noise requires a powerful transmitter which can easily be located. “And during a conflict, the innovation accelerates,” says Withington.Īn alternative method is to target the jammer and physically destroy it. Electronic warfare is a continuous arms race, as each countermeasure is met with a new counter-countermeasures in a never ending game of cat and mouse. “It’s certainly plausible that they have found a way to counter Russian jamming for a time,” says Thomas Withington, a military analyst specializing in electronic warfare But he emphasizes that anything the Ukrainians do will not be a permanent solution. warfare vehicle Ukrainain MoD In Electronic Warfare Nothing Is Permanent One way of preventing jamming is to target the jammers - like this destroyed Russian electronic. But we do not know which of these approaches Ukraine uses - if any. And smart receivers can switch frequency to find one which is not jammed. A notch filter blocks out signals which are not precisely those of the controller, reducing the noise produced by jamming. Jamming is harder to counter, but there are plenty of known techniques from the military world, such as the use of several antennas to create a highly directional receiver that can screen out jamming. This update means that instead of transmitting their actual locations, the drones claim to be at zero latitude, zero longitude, a spot known as Null Island. To make things easy for drone operators, Ukrainian engineers built a black box called Olga which plugs into the drone’s USB port and makes the necessary changes automatically. Previously, Ukrainian drone operators worked out how to modify the firmware on their drones to counter DJI's AeroScope tool, which locates quadcopters and their operators. “Maybe I’ll tell you all about it later,” Volokhov says, then goes back to summarizing drone bombs. He looks offscreen, as though there is a piece of equipment he is considering showing us, but decides against it. No problems! I could show you, but I probably won’t, because there is a certain known-how of ours. “But this problem was overcome and now it is not with us. “After arriving here it was 4 kilometers, after a certain period of time they were reduced to 2…”īut, as Volokhov notes, things have now changed. In Kherson Terra’s drones could advance 8 kilometers, but things soon got worse when they moved to Bakhmut. For a long period of time the opponent dominated us,” Volokhov says, and describes the familiar pattern of growing interference. Then, nineteen minutes in, he mentions electronic warfare. He also mentions his units experiments with using FPV drones as dive bombers, a technique which has only recently emerged. In the video Volokhov mainly talks about the different types of drone bombs that his unit has used – one derived from a U.S.-supplied 40mm grenade comes out as favorite – and the 3D-printed drop mechanisms and means of attachment to drones. The answer is at least hinted in a subtitled video posted by Mykola Volokhov, known by the call sign Abdula, commander of the Terra drone unit, which has posted many videos of combat operations. ![]() ![]() Rather than being completely eclipsed, Ukrainian drones seem to be having a resurgence. This is surprising because the counter-offensive means Ukrainian drones have to push ever further into Russian-controlled to carry out their missions. We have seen a marked uptick of new drone videos during the counteroffensive, showing small drones directing artillery fire and bombing Russian trenches and vehicles, while small FPV kamikazes appear to be taking out significant numbers of Russian tanks. However, in the last few weeks things seem to have been changing.
