How does that work? fiber optics are delicate. you mean free-space optics?

Very long spools are connected to the drone and it is flown by wire until it strikes its target.

Like a TOW missile or early torpedoes? Surprised we still use that method, but I guess it works!

Yes the method is nothing new. The novelty is FPV, considerably longer range (15km+) and relatively low cost.

TOW missiles were, believe it or not, FPV..

Optical tracking isnt fpv

here's a video from ukraine showing fiber optic cables all over the ground: https://files.catbox.moe/fx980o.mp4 maybe someone will find this interesting like I did.

Currently in Ukraine both sides are apparently using spools of fibre on their drones due to the RF environment. ISTR reading that they're able to carry several KM of fibre each.

Delicate doesn't really matter - these are kamikaze drones carrying shaped-charge explosives or anti-personnel grenades, often taking out individual soldiers one by one (as well as tanks etc). Seems wasteful but potentially the near to midterm future of warfare?

This is incredible. Especially the link below to buy the system. I see it unspools at the drone to prevent tangling. How you prevent being traced if some of the enemy’s survivors follow the thread?

How do you prevent being traced?

I believe the answer is you shoot at them with automatic weapons.

incredibly thin, hard to find fiber optic, laying on the ground in a live combat zone -- essentially a non-issue

it's the same idea as SACLOS anti-tank missiles that are "wire guided". if someone is shooting those at you, you have way bigger things to worry about than tracing cables -- you're in a killzone, so try not to die.

why follow the cable - they already know what direcion you are in. By the time they can follow the cable several km back you have already moved elsewhere. and of course you never are alone so someone else is watching for them to come and will shoot them just like any other attacker coming your way. attackers have it easier as they can stick to cover while following the cable means they are in the open in places near your line.

Your drone has a friend to tag the survivors.
Re:Portable drone jammer uses a Raspberry Pi tactical Softwa... by mattlondon on Monday February 17, 2025 @02:02AM (#43076032)
From what I've seen and read, the thing preventing you being traced by someone following the fibre is simply huge numbers of drones literally flying into enemy soldiers and detonating.

It is terrifying viewing the videos as people try and (unsuccessfully) dodge the drones, or are accidentally shot by their own comrades who are trying to (unsuccessfully) shoot down the drone, or are run-over by their own side's tanks/APCs who are panicking and trying to (unsuccessfully) outrun a drone, or are blown up trying to (unsuccessfully) take cover in a trench/dugout/building/APC/tank and a drone literally just flies in through the door/window/hatch and detonates (perhaps followed by another two or three for good measure)

Genuinely sounds absolutely terrifying, more so than any other horror stories of e.g. WW1 & 2.

To be certain, by "incredible" I meant more "fascinating", or "intriguing" and not "cool!". War is obviously horrifying and for this reason I haven't even watched any of the videos. That's what made the fibre development novel to me.

I certainly hope we reach a point very soon that we stop the senseless killing.

Not wasteful at all when compared to the cost of "conventional" munitions.

You can get it shipped today, 3km, 5km, 10km variants available! :D

gotta "send inquiry" -- may not actually be available, and pricing TBD
Re:Portable drone jammer uses a Raspberry Pi tactical Softwa... by relaxing on Sunday February 16, 2025 @06:51PM (#43073112)
free-space optics are sensitive to atmospheric attenuation and los. you mean fiber optics and be careful not to fly in a way that exceeds the bend radius.

Re:Portable drone jammer uses a Raspberry Pi tactical Softwa... by red-iron-pine on Monday February 17, 2025 @04:11PM (#43083325)
very well, and functions similar to SACLOS missiles.

arguably the same basic idea, just with more maneuverable payloads.

crystal clear recordings out there of said drones if you're willing to stomach r/combatfootage or similar
