I'm surprised this isn't already happening in Ukraine. They could fly small surveillance drones deep in enemy territory, perch on a power line, and send back lots of data. Not just video, but also sound and triangulating signals. This would also be useful in fog by monitoring major roads where high altitude drones and satellites would be obstructed.

The problem is signal jamming which forced using fiber.

So the limit isnt batteries, its fiber spools.

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.

Maybe it'll lead the US burying their power lines

The cost to do that is unimaginably high.

So was rural electrification to start with, but it still more than paid for itself. It has also never been easier to bury lines with horizontal boring machines.

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

Everything I’ve found about the drones in that conflict indicates they use automated navigation for pursuit once a target is locked, but human pilots before then.

as soon as it sends RF it'll be located and destroyed. There has been lots of work to make fibre connected drones, so that they can't be located as easily (also the pilot)

Why not lasers through the air?

you described two different steps: human pilots get to desired area and target locked. For the human part, if the drone isn't using fiber optic and is getting jammed (many types of jamming), the human pilot might not be able to communicate with the drone. If that's the case, how will the drone get to the desired area? that's where the two things i posted come into play.

How do they not work? Just fail in transmitting data completely? Do you have a link to learn more about this?

Cable breaks

Well, there's a difference between breaking and being broken. I wouldn't say 33% of all B-17s "didn't work" because they were shot down.

And we have 20x the manpower to review this footage? I wonder if you're just generating a bunch of data that cannot be practically used. "More coverage" isn't always the best answer. "Bet…

We have done automated utility inspections for the past few years. Computer vision is not a problem any more. When we were starting we had to annotate thousands of images. Today some use cases require less than a 100. More interesting problems are pre-field planning, sagging, or BLOS compliance
