Has there been any progress with coming up with a system that can _reliably_ jam them?

- dron3r 6y agoYou can jam signals they rely on, like GPS and cellular, but there are already drones that are capable of flying on vision alone, so no.
- jojobas 6y agoINS chips providing enough precision for autonomous operation over last few kilometers are rather cheap nowadays too. A small-ish plane frame could easily deliver a grenade from sleepy suburbs 10km straight to the Oval Office with only few minutes of warning (assuming somebody could actually detect it in time at all). We're just lucky nobody seems to be bothered to do that.
- implements 6y agoWell, if you managed to detect and track an incoming drone you could ‘jam’ its camera with a high-powered laser - or something that threw up a curtain of flares or burning magnesium, or whatever.
- brendawalsh 6y agoDoes that work for a fleet of 10 drones? 100 drones? 1,000 drones?
- xvector 6y agoNot sure why you're being downvoted. Legitimate concern.
- HarryHirsch 6y agoA drone swarm dropping hand grenades is like targeted artillery. Experience from WW 1 is that it's straightforward to defend against artillery fire, just retreat into a shelter. A target that's worth five dozen drones with grenades can afford a bunker.
- Zenbit_UX 6y agoSo simple in your scenario... The target just needs to jump in their nearest bunker, better hope they happen to be attacked outside their bunker eh?
- asdff 6y agoI don't know if you could ever stop a low cost drone short of using a shotgun. Even if you had some sort of directed EMP technology, the drone could position itself along the correct precomputed vector from far away, cut off electric, and glide the bomb to the target silently.
- ggm 6y agoOh great: low budget stand-off weapons. This is not going to end well.
- mschuster91 6y ago> the drone could position itself along the correct precomputed vector from far away, cut off electric, and glide the bomb to the target silently. An octocopter/ordinary drone can't do this - their electric goes out and they fall from the sky. For a glider you'd need an actual flyable airplane model (something like this: https://laughingsquid.com/a-15-foot-long-radio-controlled-airbus-a380-model-plane-taking-off-and-flying/ https://laughingsquid.com/a-15-foot-long-radio-controlled-ai...), and these are expensive as fuck - a single engine alone will run up well into four digit range, if not five digits (something like the JetCat P1000). And at that point, you could also go ahead and buy an outright RPG, should be far cheaper to acquire depending where you are, or buy a couple junker cars, load them up with fertilizer bombs, and distribute them where one expects the target.
- nl 6y agoThis is wrong. ISIS used[1] the X-UAV Talon. This is a off-the-shelf 1.7M wingspan drone plane available for about $150 without electronics (which are around $50-$200 depending on how elaborate you want to get). It's capable of 100km+ flights[3].

- PeterStuer 6y agoReliably jamming drone comms would also jam all other radio based systems in the area. You could try to narrow your beam, but that could lead to evasive pattern dodge manouvers, and would be harder against a swarm of the things. Even then, the drones could get by with extremely crude, near ballistic autonomy (erraticly fly 500m in that compass direction and detonate on the moving blob near the pool).
- dasKrokodil 6y agoWe need an anti-drone drone!
- bouncycastle 6y agoThey can just get an anti anti-drone drone
- baq 6y agostrong narrow fabric jams the rotors. there was a hunter drone product doing exactly that from above. can't google it now, maybe there was no business.
