I'm not like a drone-i-ologist or nothin, but from what I gather, both sides have gotten really good at detecting and jamming drone communication in the Ukraine/Russia conflict, which would probably make that a tough use case. I've read that the newer attack drones are controlled by a reaaallly long, reaaalllyy thin fiber optic line!
New attack models are using shielded electronics that don't need GPS and are immune to traditional jamming. Relying on computer vision and old school navigation math.
Go ~X speed for Y distance(+/-) on Z heading until you reach A landmark and then start a new set of instructions.
Yeah, but not in ukraine. They brute forced fiber, fly by wire.
Dead reckoning via inertial sensors, cameras, etc are way to complex for the flight controllers without heavier hardware since theyre hugely inefficient.
AI at the sophistication to do this stuff is essentially bloatware. Like running electron instead of a bare metal gui.
I’m interested in reading up on that. Where did you see it?
You can take a look into inertial navigation systems and then also terrain mapping

At the end of WW2 the very same happened. As if they didn't learn from history. Well, that are Chinese drones, which weren't part of the signals war then.
The idea would be to use autonomous drones, so they wouldn't need to communicate, the problem would be that the GPS signal is jammed.
If they're not communicating, how are they sending back lots of data?
I presume these are surveillance drones and are programmed to loop back to origin

Those fiber optic lines only work 50-60% of the time. Often the drones are carried 20km on foot into position which sucks as you know half the equipment on your back won't work.
Where did you see that?
How do they not work? Just fail in transmitting data completely? Do you have a link to learn more about this?

A jammed drone that's perched on a power line wouldn't fall out of the sky, and doesn't need to transmit 24x7, only when it detects some activity. The lack of a signal from it would itself be a signal of where the next attack is coming from. Anti-jamming weapons (missiles and autonomous drones) would also be useful, that lock on to any signal jamming sources and deliver the munitions directly to the target that's advertising itself.
