Russian Special Military Operation in the Ukraine - Mark IV: The Partitioning of Discussion

[Susanna]

Doesn't actually work that way

A radio source that drowns out the signal from the controller can easily be pinpointed by multilateration, it's called radio direction finding since we only need the angle to the source rather than angle and distance.
Are you talking about something else?

Yea one small problem nobody is going to build one of those just to take out one dude with a drone jammer backpack its really expensive

Thats why the backpacks the russians are making is working so well for them

I could build one with an ESP8266 and some cables, if jamming backpacks become common equipment not countering them is down to failure of creativity.

I really doubt that

1. Can't hear the controller? Revert to radio seeking mode
2. In radio seeking mode, move in a random direction. If the radio jamming becomes stronger, keep going in that direction
3. ???
4. Profit

Basically, I don't believe you. Btw kindof odd chip choice pretty sure that cant direction find/doesn't share a band with the drone control/jamming?

move in a random direction.

Thats not going to home particularly well

It's not the best chip, but it's something I've used, that has the right capabilities, and that's very easy (and cheap) to buy in bulk.
It absolutely does share a band. WiFi, which is what the ESP8266 is built for, sits on 2.4GHz just as commercial quadcopter receivers do.
One way to set it up would be "if you lose contact with the transmitter for more than x seconds and return to base mode is set to anti-jamming, obey yaw and pitch commands from serial". The ESP8266s could be used in sets, for example one per limb of the quad slaved to one lead controller (which could be the actual RX if you're willing to flash new firmware to the quad itself, dunno how much customisation is done on them). Each has an antenna positioned such that it receives from partially overlapping cones and is otherwise shielded. Calculate yaw and pitch toward strongest signal, and tell the quadcopter controller over serial. You would want the quad to first rotate such that the jammer is in front of the quad, on the edges of two cones, and from there it's just a matter of rocking back and forth as you dive towards the target. When left front receives stronger, yaw left. When right front receives stronger, yaw right. Thinking about it you'd also want one wide cone on the bottom, to direct your pitch.

This approach would be easily misled if multiple sources of jamming are present yet spread far apart, it would dive towards a spot on the ground between them. But from the drone videos I've seen, soldiers seem to stay together.

You can do it simply by feel pretty easily. The video signal fades a bit when the drone gets somewhere close. EW is not a digital knock-out. I've seen several drones hit targets with EW and the drone operator maps out where the signal gets bad and uses that to hit where the EW is.

Here is a good example of that. Don't watch if you don't want to watch someone die etc.

To my knowledge, Russia have never been big on HARM missiles. Or drones.

That's not to say they can't - they have always been good at electronics - but don't expect a HARM quad copter carrying a grenade in a glass this side of... ooh... August.

Edit: make that June.

I've heard that too. Really want to get a cheap drone for fun but the battery life sucks balls.

I'll never understand this nonsensical "mongolic horde" insult. Mongols were badass!

@snov is right. "Point to the strongest radio source of this frequency" is a super simple task and that chip, and other sub-dollar chips has enough processing to be able to do it without issue.
An 8266 is a good choice because it is cheap and it has a mature development kit.
EDIT, you don't even need a microcontroller for that. Just 5 spiral coil antennas tuned to the freuency. One pointed forward and the four others off slightly out of center in each corner. The control loop is then : if strongest signal is from antenna pointing straigh forward then continue forward. If strongest signal is from one of the others, then turn towards that antenna. A pure analog circuit could do that easy.

Personally I would go with a 5$ chip with a 10$ camera and just run image processing to track the human shape in the centre of the camera. A 5$ ARM can do this with no effort. That would allow to track and target any human in its sights instead of just the human with a jammer backpack.

When someone (typically a hairy sole Romanian) calls me a mongoloid, I just say thank you! Being compared to mongols is a great compliment, horses, horse archery, conquering, throat singing, all of these are marvelous.

Agreed, but the issue is getting that analog control circuit to tell the quadcopter what to do. The quad will listen for either serial commands from the RX (modern method) or square servo pulses for each degree of freedom (old method). A microcontroller can easily bit bang the serial commands or output servo pulses on its pwm pins.

 

[Kankichi Ryotsu]

They do realize the mongols were great conquerors right? That's not to say they weren't brutal, but it seems kind of schizo of the nato propagandists to paint Russia as this incompetent backwater region who can't into kyiv while simultaneously saying putin is literally Gengis Khan. Which is it? Are Russians incompetent or are they the most fearsome land empire to exist?

This is outside Avdeevka. The Ukrainians are having a hard time reforming their lines here. The purple is the regions Russia took today. This is turning into a real bad situation for the Ukrainians.

Ukraine has had small holes that they could fill easily enough the next day. The situation around Avdeevka is turning into a big hole that keeps not getting filled. If the situation here is not fixed soon by Ukraine, they may lose the opportunity to ever fix it. The longer the defenders here keep getting slammed the weaker and weaker they get. Without reinforcement they will simply break.

I know I might sound like a broken record but this is incredibly bad for Ukraine. If a big enough hole opens up the entire Ukrainian line will be nonviable and a massive retreat will be necessary or a massive chunk of the Ukrainian army will be destroyed in short order. I can't emphasize how bad this is enough.

They might stabilize this with reinforcements but everywhere has pressure being put on it and if they pull from somewhere else that place will have the Avdeevka problem. Maybe Ukraine has some super secret weapon to save themselves but I doubt it. I'd say they could retreat and give up a bunch of land in the Avdeevka area but Ukraine has demonstrated that it is extremely unwilling to do anything like that.

The definitely subscribe to the Zap Brannigan school of thought that retreating is for cowards and Russia lost the war because a year ago they chose to sacrifice land to protect their soldiers until they had control over the theater.

Khokhols refer to Russians as katsaps - butchers.
One can probably see how that can be an insult during peace times.
During war it becomes "not the own they think it is".

In a belated celebration of Defenders of the Homeland day, here’s a video from Aveyevka:

An old man got reunited with his grandchildren after two years. When the Ukrops tried to evacuating him, he refused, waiting for the Russians to liberate his home.
