Downloading Images from Russian Satellite
ฝัง
- เผยแพร่เมื่อ 29 เม.ย. 2021
- My first attempt at getting images from the Russian "Meteor M2" weather satellite.
More info and step by step instructions for how to do this are here: blog.chaospixel.com/linux/201...
Edit: I'm now using a different program for this which is more automated, called Raspberry-NOAA V2 (It does both US and Russian weather satellites). More info here: github.com/jekhokie/raspberry...
- Software Defined Radio and antenna kit: amzn.to/3xW0gtF
- SAWbird+NOAA Amplifier / Filter: amzn.to/4dqLVFU

Imagine accessing a satellite to see what the agencies are trying to spy on, only to reveal seconds later a satellite photo of your exact house.
Thats when you take you pants off lay in you back yard and allow them to enjoy the scenery
Better yet a super close up of your face

That would be scary
honestly if you're casually accessing a foreign agencies satellite you should expect that
That ackward feeling you get when you try to tap into a Russian weather satelite, and it pulls up someone's game of Defcon. Then the air raid siren starts sounding outside...
DOAH! 😆
greetings professor falken shall we play a game
@Bigga Nigga Yes I think he is just receiving the data transmission, like a person listening to radio, so should not be a problem.
A good example of how someone is brainwashed by their government propaganda to the subconscious level
It's raw image data, you could probably run it through VLC and get a decent signal that might update
That shifting signal appears to be the doppler of the signal as the sat breaks horizon and gets closer in orbit. Thats another reason for using helical antennas for sat work
Thanks for confirmation. Was my first thought but I’m just a noop
Im completely ignorant, only watch because im interested. What makes helical antennas different?
@@hoteny Short answer is that if a satellite only had a vertical antenna and it moved across the sky the a ground station would see a slightly different polarity depending on where the sat was in relation to the ground station which would result in greatly varied received signal strength throughout the orbit pass. A helical (circular polarization) does not have this problem since rotationally speaking it doesnt matter what angle the sat is as long as the direction of rotation is the same( clockwise, counter clockwise)
You sure? More likely that it was a bird, maybe a plane...
@@FartInYourFace234 a bird? bro...
I take back my statement on the a/c suit video: THIS is how urban legends/creepypastas start. Downloading mysterious signals from Russian satellites, that's the sort of thing a protagonist does before he finds out there's a giant monster that's disguised itself as a city and it's eating people but the government is covering it up but the Russian sat shows it for what it is and then someone from a three-letter agency shows up. Then the world ends, usually.
Heh, I saw your other comments pop up in notifications but then TH-cam seems to have eaten them. Not sure why, I think it auto-deletes anything with a link or that it thinks is questionable.
I’d like you to write that story.
@@seanfaherty That would be awesome!
I was a resident of the monster city. I managed to escape, and have been on the run from a satellite ever since.
That would make a fascinating “B” movie - the type that achieves LEGEND status! Do develop it 😅
This is the kind of person you want to be friends with. Probably likes craft beer, probably has great conversation, probably joins you for tabletop gaming and is a competent and polite player.
That's the type of people i surround myself with, i am like that too
If you arent playing with competent and polite people, youre doing it wrong
@@flandersnatch2285 I try. But many times, there's someone at the table who is:
- Polite, but struck with constant analysis-paralysis, slowing down the entire table.
- OR, less common (thankfully), competent, but a total dick. AKA, complaining about the game, the snacks, uncomfortable chair, etc. Or just plainly, looking at the phone during the game!
@@DudeWatIsThis interesting. Analysis paralysis is fine, there's plenty of ways to work around that which your GM can implement.
From asking people to think about what they're doing on other peoples turns and deferring turns, to turn timers and "up next" warnings, and a whole bunch of stuff in between.
For me and my table, players being slow to decide isn't incompetency but accomodating those players while slowly addressing the issue is part of being polite.

I want to say that in Russia it has recently been a very popular topic to receive images from NOAA satellites. Everyone who bought an SDR receiver for himself, besides listening to military negotiations, watched satellite images.
какие ещё военные переговоры ты там прослушивал? Военные шифруют свои переговоры.
listening to military negotiations? Is there any videos of people doing that?
@@Neilukuk it's a common practice. No one ever thought of doing a video about it, because its too boring
@@Neilukuk Secret military communications are of course encrypted. I'm talking about ordinary negotiations between the military.
@@keenasp1869 Not over military radio, it's encrypted? People would definitely report on it if they could hear in to it.
This is definitely one of my new favorite channels, linux, old computers, doing sketchy stuff with satellites using stuff from your garage, perfection
Edit: people from my friend groups keep finding this video and comment because they are also weird nerds, hello weird nerd friends
sketchy stuff xD
It's actually fully legal to RECEIVE signals from ANY source. Where the law comes in is TRANSMITTING signals 😉
@@eijmert go hard, play with 210 volts of unsympathetic angry electricity and point it at the sky to get some data, sounds like a chaotic phone call with the gods who in this case are very chill and are saying "chill, look at yourself" but in Russian.
Genuine question, what's the point of making your sexuality your entire personality if you're just going to overlay your Fatherless Flag with a retarded skeleton?
@@SSZaris I mean for starters that's bullshit, it isn't fully legal to receive signals from any source.
Secondly with Satellite signals, the reception of these signals can be legal, but the decoding and use of the data can be subject to legal restrictions. For instance, it is generally legal to receive satellite television signals, but it would be illegal to decrypt pay-TV services without authorization.

This is the content TH-cam needs to recommend to me more, genuinely intriguing DIY tech content. Nice video man, you explained everything very well. Subscribed!
the drift of the signal you're referring to at 1:40 ish is partially caused by a phenomanon called Doppler shift as well as refraction of the signal by the atmosphere, it's being broadcast while it's moving towards you which causes the signal to effectively be squished and therefor appear to be broadcasting on a higher frequency. You might see it do the opposite as it goes out of range. Idk if you mention that I just saw this.
thats blueshift isnt it?
god i love this part of youtube.
@@Helperbot-2000 Dopplershift results in blue/redshift in light, for e.g. sound it results in a higher/lower pitch
Ohh I think I get it now. The doppler effect probably changes with the angle the satellite is in relation to you. When it's far away at the horizon the doppler effect is the "strongest" or at it's highest point in frequency. As it comes closer and then directly overhead the speed the satellite is traveling has less and less effect on the signal. Because when the satellite is over head, the signal comes from above and doesn't have the component of the speed the satellite is traveling at. Am I understanding this right?
@@night__walker Enough to grasp the concept, yes. It's the exact same reason that sirens pitch up when moving toward you and pitch down when moving away.
I believe one of the Meteor-M satellites was struck by a micrometeoroid or space debris and lost its primary temperature control loop. It also started tumbling but they were able to recover it partially.
It's been half-dead since then.
Maybe it's the satellite that you picked up: It would explain the low signal strenght, broken image and not-quite-top-down camera angle.
That would be super cool, imagine picking up a half-dead, probably decommissioned sattelite still trying to do its job and transmitting.
@@TheNicestPig thats some cowboy bebop stuff right there :D
@@szylaj So long as we don't start getting laser drawings of animals in the desert, we're okay.
@@TheNicestPig I know, right.
And even cooler are zombie satellites that are presumed dead and randomly resume operation after a long time:
Take a look at LES-1, lauched in 1965 it resumed transmition in 2012 after more than 40 years of silence.
Or AMSAT-OSCAR 7, presumed dead in 1981 after a battery failure, it was discovered in 2002 that it was still intermittently working when its solar panels were fully illuminated by sun, but even cooler that it had be secretly used for communication by polish protesters during the years of the martial law to avoid tapped phones.
@@Tbird761 broo whats that a reference to
I have worked in earth and space science education for years, including many years as a planetarium director, before becoming a TH-cam creator, and I've never noticed that giant impact crater in Wisconsin before now. I learned a lot in this video aside from the crater, but darn I can't believe I never knew about that crater until tonight. Thanks, man!
"They're a lot better quality than the NOAA satellites." That's because they're a "weather" satellite not a weather satellite.
The image quality was better, but the satellite quality seems iffy. This one was tumbling sometimes and now I think it's broken completely.
@@saveitforpartsr/wooosh
@@alexgoodkind7110get out of here, redditor
Image quality on satellites launched between 1980 and '93, it's surprisingly good, for a weather satelite. I wasn't expecting it to be such. And of course, it's obligatory to use sketchy linux programs nad mysterious steps when operating on Russian satellites, how else would you have fun

this guy is awesome. he's still hearting comments even though the video is 2 years old
I keep getting comments on it, so I try to keep reading them!
I seriously have no idea what you are doing or how you are doing it but this is amazing. I'm going to keep watching.
I love how you go about building so much from scrap. I think that is a sign of true passion and intelligence on a subject. Kudos!
Short storytime. Years ago I broke my leg in a bad way. I was stuck in my house for 6~8 weeks with no internet or cable. I watched a video using my cell data of how to build a digital t.v. antenna for local channels.
The only part I had was the coaxial matching adapter. I'm not even sure why I decided to keep that thing all of those years but I'm glad I did. I thought it was called a bohm or something like that but I must have imagined that part. After digging around I found some 14 gauge copper wire from some old romex, two of those cooling racks for baking cookies, some drywall screws with washers and a 2×4 to mount everything on. It looked like something out of Nikola Tesla's lab hanging from the ceiling.
I was blown away by how well it worked. Almost 30 local channels in clear digital. From then on I at least had something to watch.
Your channel reminds me of that. Having the knowledge and the resourceful nature to do so is something you really can't learn in school.
Thank you and keep up the good work.
Be well and good day!
-Sputnik
Thanks! Hope your leg healed OK, that sounds like a rough time without much to do. I've been surprised by what antennas can be made from junk without even knowing much about the theory, it's fun to play with!
@@saveitforparts What I've seen on your channel proves that high tech equipment isn't really all that high tech. Yeah, the leg healed fine. I also had my girl pug Lola Scrunchie Face Von Wiggles to keep me company. I got so bored the one day I built a radio controlled six legged robot out of K'neX and old Futaba radio parts. Lola would get so riled up over that thing. She was such a weirdo. Your videos brought back such good memories. Just geeking out on what you love. Thank you.
@@awolslaboratory1388she sounds like a good dog. If she's still around please give her a scratch behind the ear from me
@@awolslaboratory1388 A bit late here, but on the comment "high tech equipment isn't really all that high tech", it applies to way more than you'd think. The core science behind how frequencies, signals, hell even data (bits) is still the same, we've just found different ways to use it more efficiently for the applications they're used for. The majority of "industrial" machines I've worked with are actually super simple under the hood, but most also have the ability/power to revoke your living privilege so a lot of the design will go into safety as well as function.
Before someone comments, I know that I'm generalizing and that there are outliers, but as a rough picture, Electrical, Computer, and Mechanical Engineering programs at schools across the country are still teaching the fundamental classes (Circuits AC/DC, Physics, Instruments and Controls, etc.) the same way they have been for the last 20-30ish years. We still widely use the same theories and laws as they did back in the 80's/90's when designing modern electronics, albeit with some new techniques along the way. And that's not to say there haven't been *any* important changes since then, but big-picture, we're still using what we have been for a while.
That signal that’s moving through the frequencies at 1:40 is likely blueshifting as a result of the Doppler effect as it closes its distance to you. You may see it start to do the opposite as it passes you.
Russia is nazi country, do you agree?
В университете на магистратуре дипломную работу писал по обработке информации со спутников. А тут чувак просто для прикола этим занимается))
3:35 The flashing dots shown is a representation of the data "Constelation" as used by QAM "Quadrature Ampltude Modulation". In QAM 256 there's 256 combinations of phase & amplitude, so any digital value between 0 & 256 can be sent by one Symbol rather than 8 bits. It's a form of compression, each symbol represent 8 bits, which is far faster, but it does degrade noise tolerance as the number of Symbols &, hence, compression is increased.
who would ever do qam256. at that point its like .2degree per phase, amp shift smt. noise would be way crazier
@@lizexi7115 QAM goes all the way up to 65536, so 256QAM isn't anything special. You'd have to ask the people who developed the standard about where it would be satisfactory to use.
Yup, same method is used for Wifi.
@@lizexi7115 Wifi 6 uses 1024-qam. Modern cable plants for DOCSIS can go to 4k qam, and some targets for 16k qam by 2030.
I've been binge watching your videos for the last few hours and these satellite capturing projects are extremely interesting
I don’t know how I got here or what any of this is but it’s extremely interesting to watch. It’s always cool to learn about what people are doing, especially when it’s something completely foreign and new to me. Thanks for the content.
First video I've seen on your channel now and I'm instantly subscribing, I want to watch more of this and maybe get into this sort of stuff myself, looks real fun and interesting to watch. Great video overall and amazing that you got a picture out of it!
You have great projects, keep up the good work! You are helping a lot of people get past block points and answering questions I didn’t know to ask. Thank you.
Damn.. how is this not on trending
From a young man who feels like an octogenary for not knowing the most basic thing about coding and/or engineering, this is amazing. It's like magic, really, I could barely understand any of the technicalities, but it's interesting to see how we, humans, expand our ingenuity with time. Pretty cool.
Nice video, I love consumer SDR stuff.
3:35 is Quadrature Phase Shift Keying (QPSK) demodulation. The received data represents the phase and amplitude of the signal. In QPSK, the phase of the signal is used to encode 1 of 4 phase states, represented by the four corners of the graph. Each state represents two bits (00,01,10 or 11). The closer the dots on your graph are to the four corners, the higher the signal-to-noise ratio and subsequently a lower bit-error rate.
Amazing project and results! I watched so raptly, just finding out you could successfully track the presence of a signal (first half of the video) was awesome, since I would think it's quite hard to even know if there is a signal going out or when, it all mixes with the background noise. Getting an identified signal is already a major achievement. When you successfully decoded a transmitted satellite image from it (second half of the video) it was jaw-dropping. I'm imagining reverse engineering an unknown format and how hard it would be, I can't even imagine reverse-engineering a format that that you have to find and filter out from background static, even if you did find random scripts online that helped. Epic achievement.
There's some info online so I'm not going completely from unknowns, it's still a little tricky to get it to work! Sadly this satellite has now died or at least partly broken since I made the video, but the NOAA satellites I've mentioned elsewhere are still working.
Really love your work. I got my foundation licence (uk), about a year ago. Got into sdr but the lack of support when installing software made me walk away, alongside a very unwelcoming local radio community. I really enjoy watching what you do. I wish you lived in Bournemouth!!
Strange how groups in the UK can be toxic at times, I would have thought local radio community would have been very interested. I used to live in Pokesdown, do you know the area?
@@favesongslist wowsers! Yup, know it well. I'm in springbourne. I visited the club at Cobham. Full of lovely people but it turned a bit sour when introduced to a sizeable minority who said: "well mate, as an M7, you can call out CQ all you want but....well, you know" There was much more so I didn't bother going back. I'm still blown away by the Pokesdown link. It's a small world buddy.
Wow! Around 30 years ago me and my friend found short article in our russian magazine - "how to receive satellite signal". I sure that was predecessor of Meteor M2. We have built double spiral antenna exactly as yours, my friend made a receiver, and I've developed sw for old russian replica of PDP-11, to process received signal. It was has not enought memory to draw image, and my software prints out scan lines received from that satellite directly to paper :):):)
As soon as I feel smart I see people like this man who remind me there’s so much more to learn 😂

Wouldn't want to be this guy's neighbor and catch an iskander missile while asleep
that meteor m2 LRPT Demodulation table at 3:59 looks very very similar to the QAM256 modulation constellation graph table that we use as ISP field technicians, those typically show actual bits of information in each little square since it would be 256 by 256 divided by 4 quadrants.. the more sporadic and spread apart the bits are from their little box margin of error is what results in a higher BER (Bit error rate) or to be simple.. data loss

This is a great image capture! At about 05:26 in the video, your cursor passes by the ORDOVICIAN ROCK ELM IMPACT STRUCTURE. An ancient meteor impact sight in western Wisconsin. The snow covering the region enhances the appearance showing the outline of the disturbance. It is thought that this may have been part of a single impact event with as many as four impacts sites spread out from Oklahoma panhandle to Thunder Bay, Ontario. *The Ordovician Period lasted almost 45 million years, beginning 488.3 million years ago and ending 443.7 million years ago.(*UCMP_Berkeley)

That's all man, keep on rocking on and well done
Yeah it's fine, it goes off to the side sometimes but whatever :-P
First time the TH-cam algorithm recommended me something good...
If he's on US government lists, it's to make him merit-based job offers (pretty rare that government competes with industry but more common in STEM). If he wanted to, he could have a job having people in suits shaking his hand congratulating him for work he considered "meh". His mediocre is competitive with some of the smartest of the smartest, and I'm saying this not because of space and satellites per se. It's because of the RF engineering background. If he isn't one, he would take to it like a fish in water. And that is material so challenging to even study let alone apply practically... it makes electrical engineering graduate students cry and have sleepless nights. Designing complex IC is another. The people who tinker with stuff like this are the ones everybody wants to hire.
This man has a good degree of knowledge in a LOT of EE/CS related disciplines, but it's the RF eng stuff that gets me. I'm basing all of this off of only 1 video, but I want to explain why this is really impressive beyond the obvious. He's working at a graduate level here, or future grad student. I don't know. But this is really impressive to me.
Just last decade, I used to see a bunch of haggard EE grad students, some in PhD fellowships or other programs where they're expanding upon existing knowledge. The degree isnt what's important. This guy might have written a dissertation and 100 published papers, but if he did or didnt do that? Doesnt matter. You have to really love this stuff to do it at all. I'm saying this because just like my impression was formed in a short video, he's being even more humble than other smart people you see making these cool science project videos. When people look smart even next to people with people attaining graduate degrees in the same field, catches special attention and it has nothing to do with receiving signal from a russian satellite. Nope, it's all the setup he did before turning on the camera. He's working with some of the most abstract concepts in applied mathematics, imho.
RF is one of the most abstract areas of EE, and everything is abstract. I'm talking about: you take your questions to maths people, not other engineers. In terms of difficulty: some of the math is so challenging that it reached what I call the "descent". If you look at some of math's greatest mysteries, it isn't pagefiller type cartoonish style. It's literally a few characters. The math side starts to LOOK simple again. What looks simpler to a 15 year old on a page is something that strikes fear in the heart of grad students.
I don't wanna pry into this guy's knowledge or what he does besides making awesome YT videos, but this is especially difficult to make look easy. I guess I should watch more. Great attitude and approach to all this. It's crazy difficult even if it's just a fun project, so you seem like someone who's going to do very well whatever path you take. I hope you keep the great positive attitude! Thanks for showing us this project. It's sweet
Are there any good RF engineering resources online you can suggest?
