Ukraine is constantly inventing new techniques that are re-thinking what drones can do.
Recently they have been using them to drop spikes to slow vehicles which are then hit by a second set of drones.
At some point soon these drones will have specialised capabilities and will go out in swarms to autonomously figure out how to take down objects.
- chasd00 3y agoAren’t these drones regular cots drones with some modification? Wouldn’t taking the door off a microwave and pointing it at the drone cause it to fall to the ground? Surely it’s more complex than that and I’m missing something.
- sandos 3y agoObviously Russia is already doing massive amounts of radio interference, that has always been a problem, which Ukraine has partly overcome. Partly. Googling for it you can see that it is massively diminishing the usefulness of drones for Ukraine.
- Log_out_ 3y agoJammer hunting drones already exist. In fact that was the idea behind the Shaheed predecessors in the first place. Set a course, then home in on strong em devices.
- stackedinserter 3y agoFrontline on both sides is saturated with electronic warfare system which are essentially microwaves with open doors. Both sides put them on trucks, armored vehicles, set up near trenches and even carry on their backpacks. There were absurd cases like this https://imgur.com/a/4LqgLED https://imgur.com/a/4LqgLED Drones evolve under this pressure. Dynamic frequency changes, computer vision, maneuvering (like "go up when lost signal") and many more counter measures are adopted on both sides.
- mig39 3y agoConsumer drones already deal with a hostile RF environment well. Finding the frequency with the least interference, using a wide bandwidth for control, and a different one for video, and programmable signal-loss behaviour. Cities are hugely hostile to low power transmission, especially in the 2.4 and 5ghz frequencies. The effective range of cheap DJI "mini" drones in cities is measured in kilometres. If you get away from the city, you can double and triple your effective range.
- Gud 3y agoWe are not talking "interference", but an enemy actively looking for your signals and overpowering it with massive high powered RF. Flying your drone around in a city is not the same as flying it against an opponent skilled in electronic warfare.
- RealityVoid 3y agoMost drone RC systems use FHSS. Those make them resistant to naive jamming. You can get fancy with jamming, but so can the way the FHSS works.
- fullspectrumdev 3y agoNo. That’s been tried already lol. You can jam the signal, but you can work around signal jamming in software by having it back off or gain altitude.
