With Starlink internet, data is continuously being sent between a ground dish and a Starlink satellite orbiting 550km above. Furthermore, the Starlink satellite zooms across the sky at 27,000km/hr! How can the dish and satellite maintain a continuous connection? And then how is data sent back and forth? Well, in this video we're going to dive into the inner workings for the ground dish and Starlink satellites, and see how a beam of data is formed, how this beam is swept across the sky, and then finally what exactly is in that beam that allows for incredibly fast internet! This is an incredible feat of technology and engineering, so stick around!

How many shooting stars did you see throughout the video? Post what you counted and we'll pick a random correct comment to receive a prize. Also, check out the Creator's Comments found in the English (Canada) subtitles for many additional details. Note: you can access them via the options button -> transcript -> English(Canada). FAQ: Q1) Do the two phase shifts from beam steering and 64QAM mess each other up? A: No. For transmission, the data is encoded into the 64QAM signal and sent to all the beamformers where then the beam steering phase shift is added. Then the signal is sent to the front-end modules which increases the power for the patch antennas.
12 shooting stars Branch Education!!
Almost 10 times🙂
i think about 12-15 idk
42
22 I'm very sure
Way cool. Very interesting process. I'm glad there are smart people in the world who understand all this stuff.
Hello Zack, it's nice that you too like these type of videos. Have a great day.
cool
It is the job of an engineer man
Nice to see you here Zack
Hey! Jerry, don't u think Elon musk is a con artist? He is just lying to his investors and the customers, his cars are a safety hazard
The fact that a TH-cam channel produces greater content than a big science tv channel while in the same time making it easy to understand blows me always.
Your videos are so good (and infrequent (in a good way (for quality))) always leave me wondering how do you people make do.
Anyway, keep up the amazing work.
actually fucking nuts that this content is available.
hugely underappreciated channel.
I greatly appreciate it! We're slowly building a team... to make it more frequent, but still maintain the depth and quality. tbh, it's always a little boggling how cursory a 2 hr long science special on 'quantum computers' or 'some other complex topic' is when it's on the TV science channel. Like I love it- but still it doesn't get into the deep details.
@@BranchEducation exactly. Someone who see this kind of stuff doesnt want to be just told that the dish uses math to boost the signal. He/she want to learn how .
What is this tv you speak of? It has channels? Is it like a serious competitor to TH-cam? Sounds like an interesting concept, what's the website address?
@@BranchEducation you made this video unwatchable. stop being so cringy. "dishy" ... WTF don't you have any respect at all towards your viewers ? do you think we are special needs ?
With my degree in physics, all the concepts are pretty natural and intuitive for me, but my mind is still blown to realize that some engineers and technicians actually made it real, and error proof, and commercialized it! And as a teacher, I can still say that you did an amazing job explaining how these things work. Great job, and thank you!
I agree, as an engineer the concepts used are very familiar. Got a chance of use a dish last week in the middle of nowhere and it blew my mind. Its crazy how long we have evolved in the past years where we SMS was mindblowing.
Give God the Glory great things he has done!
An electronics engineer, all of these technology, physics and protocols are familiar to me and very intuitive, even mathematics in physics level. But the amount of technical math to pull this off is an I don't fucking know how. To have this precision is god stuff but it's only one of these technologies.
This is the epitome of TH-cam. The fact that such high quality educational content is free is one of the few things that give me hope that technology and understating is the true epitome of research of advancement in society.
My thoughts exactly. As much as it’s been polluted by garbaj 2+2=5 nonsense there is stuff like this that shines through and gives hope
We need more videos like these for our children and less garbage on TH-cam.
I am absolutely ASTONISHED by the technology behind Starlink, and equally STUNNED by the effort Branch Education put to make it so accessible... This is very high quality content !
Thank you! We appreciate!
Satellites don't exist. GPS not working in ocean. GPS is just the triangulation of cell towers. Internet cables are buried under the ocean. Time to wake up. Trust your senses..
_ Satellites don't exist. Those are cartoons. Men send signals to the sky at an angle (a solid dome placed by our Creator), and it reflects those signals back to flat plane(earth) at same angle. Everything is stable, the ground antenna that sends, the earth, the dome, the ground antenna that receives. Universe, solar system do not exist. Are you saying there are bus sized tin objects that float above our heads about 700 km which is supposedly 2000 C hot and doesn't melt the trash cans(so-called satellites) ??
_ Does it feel like we are travelling at 66600 mph around the sun? Earth inclined 23.4 degree? 90 -23.4 = 66.6 now you see it's 666 everywhere.. it's the devil's number.. YOU WILL KNOW THE TRUTH, AND THE TRUTH WILL SET YOU FREE.
_ Why mercury and venus show up in the night sky? Can any scientist (Illuminati) explain this? No. All 12 months, we see the same stars in the night sky, but we should see some other stars which are in the other side for 6 months. Globe is busted again.
_ Antarctica is the surrounding 300 ft. tall ice wall of our flat earth, and illuminati won't let anyone near by to discover that the world is flat, it's the most guarded place on flat earth. There is a treaty signed by 50 countries that no man can get to Antarctica, because it's the surrounding wall of our flat earth, and it extends very far.

Why i cant see the other comments?
@@beaconing7689 Good question
My background is in electronic engineering. I've watched thousands of TH-cam videos and I've never seen a more professionally made and complete video as this one. Just enough detail to not be overwhelming but complete enough to get the thought across. Excellent.
Starlink is kinda cool
I believe this might be the best video I have ever seen on TH-cam in my life.
No exaggeration.
The technology of starlink.
The script of this video.
The animations.
I’m in awe
I have been in the RF, Radar, and Comms industry since 1972. I have to say this is the best explanation of RF and the Antenna theory explanation I've seen.
Thank you.
Network engineer here, with a physics background.
Refreshing to see an accurate, techy video that breaks down so much of the system.
It's a rabbit hole of information but you managed to cover everything in enough detail to introduce it, while allowing the audience to choose whether they want to go further into the rabbit hole.
Many of the techniques used by starlink are used in your home WiFi, or other systems you're familiar with. Starlink brings a lot of things together (including Elons infinite wallet) in a way that hasn't been done before.
Thanks!! I appreciate it. Yeah- I like to think of it as supplements to courses that could fit in any 11th / 12th-grade science curriculum, and really expose students to engineering.
@@BranchEducation bro you are a genius please make a video on how to make my wife touch me
Like kessler syndrome?
Very cool
i wonder if in the future this Starlink will be able to takeover all our telco services :D
This is the best explanation of phased array antennas that I have ever seen, especially from a layman's point of view. Great job!
It feels like I actually understood something rather than in some discovery channel documentary about any physical/technological topic where they simplify so much that you can't really understand it and they interview a dozen scientists making emotional statements about how marvelous and mysterious it all is.
Dude, are you not aware of the truth yet? Earth is not a globe, universe doesn't exist, sun & moon are the same size, made up of plasma hovering above our flat earth. If earth goes around the sun, then why do we see same stars for all 12 months? Shouldn't we see different stars on different directions? Globe liars got busted once again😁 solar system, big bang, planets are fake (photoshop). Are you people even real?
Michaelson-Morley and Airy's experiment were supposed to prove the earth's rotation, but those proved the earth doesn't spin, they bite the dust, many experiments ended up with the result of non-moving flat surface. WELCOME TO REALITY. UNIVERSE DOESN'T EXIST.
Governments , nasa, isro have been lying this whole time.
Amazing thing about this video, is it explains what defence departments around the world spend so much money on. The amount of effort in phased array applications in electronic warfare are insane!!! Billions and billions of $$
I am a radio engineer. I just want to say....Waw, explaining beam forming using massive antenna array ! That is very hard thing to do but you had the simplest and clearest explanation that I have ever seen!
This channel has to be one of the greatest channels on TH-cam. Actually, the best educational content ever created in media.
You don't ever get this level of detail and explanation on a multimillion dollar production on TV.
Small nitpicks - in the orbital animation at 2:50 TV satellites should be shown to be geostationary, orbiting above the same area as the earth rotates. This is important because it explains why TV dishes can point at a single point in the sky, while Starlink beams need to be electronically steered. Furthermore, while the earth is correctly shown as rotating counterclockwise from the north pole, both satellites are orbiting in the wrong direction, east to west, while nearly all satellites orbit west to east to take advantage of earth's velocity.
Overall though, very nice video that explains complex electronic and communications concepts.
Thx for the added details
well starlink also needs to transmit signals, so not only the movement of the satellites is what requires it to be electronically steered (phase arrayed)
Yes the retrograde orbits love it! Doesn't look like many people noticed though don't see very many comments. I think somebody got too focused on explaining phased arrays and forgot about orbits
And you can transmit data with a traditionnal dish if you have a Block upconverter, like in a VSAT
I wouldn't say that's nitpicking- it's just plain wrong and misleading. After I saw that I stopped watching.
I'm an engineer, and thus I was amazed by the level of detail provided here, it is very educational and in my perspective one of the most valuable videos over the internet for the content, simplicity to explain, and understanding level of the subject explained. Please continue to do more videos like it, I'm for sure watching this video a couple of times more to pay attention to details that I missed on the first watch. Kudos to the people that created it!!
These days the Yoytube and Tiktok college are much amazed me than those knowages back in school
Have a look at the signal path channel where the guy does microwave analysis of the dish PCB
My husband is an EE and watching programs like this with him and our 6yo makes explanations make sense to us!
im engineer too and its so lovely video he made it easy for people to understand it well
The amount of dedication and detail of this video is out of this world, literally a master piece. Thanks.
How incredible! I made a 4x4 phase array in undergrad and that was weeks of headaches and only worked in simulation. I can’t imagine getting something like this off the ground. Your videos are of amazing quality!!
As a satcom engineer with over 40 years of experience in the field, I can say that you did a really good job of distilling this information down to something a layperson can grasp. Well done.
I would point out that in addition to receive only satellite TV antennas that communicate with geostationary satellites, there are also two way antennas that communicate to GSO satellites as well, along with other variants which provided two way communications with other non-geostationary satellite networks in different orbits.
I'm glad that you enjoyed the video!! I included details for geostationary internet in the creator's comments, but I don't actually know exactly how non-geostationary satellite networks work.

@@BranchEducation Wow! What a candid, honest answer. The world needs more educators like you.
RideGasGas, thanks for your comment. Glad to know there are few old guys still interested in this stuff. I first worked on analog computers in nuclear bombers 55 years ago. It wasn't until 37 years ago, though, that I got the chance to work in computer data communications for a large telecom. As a sys tech in a major data center, I was disappointed that their tech was so old school in the late '80s. All the computer data connections were via RS-232c (25 pair) cable. It wasn't until the very late '80s and early '90s that they began using TCP/IP and RJ-45 in house. Even then, it took them many years to replace everything. By then, I had retired. You'd laugh at the punch cards and paper tape we used on some minicomputers to load data. LOL! All that was from a center where we monitored datacom from several mainframes, 2,000 minicomputers, and around 30,000 servers on a WAN that covered 9 U.S. states.
I'm a phd student working on these kinds of projects, and I want to applaud you. This is the cleanest and clearest explanation of phased array antennas I've seen and will be super helpful in helping me explain what I do to others
What's your phd in?
@@BranchEducation Computational Electromagnetics. We do a fair amount of metamaterial/metasurface (the latter of which is often a variant of a phased array) design, simulation , and optimization work. Your explanation of beam forming I think did a great job of striding the line between useful info and minutiae. No need to go into full array-factor theory for an introductory video, but still get the point across with the appropriate nod at the end about side lobes and such.
That sounds super cool!! Would ya perhaps be familiar with smartphone antenna design? Or perhaps wifi router antennas?
@@BranchEducation the theory behind them yes, those kinds of design no. Most of my work is more in the optical range.
@Ben Zerbe ah, well if ya have any video topics in mind, feel free to email us
I worked as a radio and antenna engineer for over 30 years. This video really provides an extraordinary explanation. Thank you so much for giving us videos like this. We are waiting for other great videos
_Those little details in the animations that make them technically correct are a HUGE aid to correct understanding. Your animations are far beyond just pretty pictures, and it shows! Your videos are amazingly good at helping engage the next h neration of engineers and scheintists that will hopefully fully make some thing far better than Starlink one day. My deep, deep gratitude and admiration for what you do._
Wow! I'm a retired Nuke Engineer with a BS in Physics. This brought me back to the days of being an undergrad trying to comprehend antenna theory. My early career was in submarines where I got to see the phased array stuff in the real world with sonar and radar. Great video!
Nice video.
As an engineer and semi-physicist who understands these topics quite well, I was looking for a summary/visual to help explain it to less technical people. This is very well done, and unlike many presentations on the internet, there is no glaringly wrong information. A testament to the research done. Assumptions and simplifications are identified. Good job indeed.
I was blown away when your team explained cell phone and display technologies, and now you take it to another level. Salute to you!
I want to say that the quality of this video blows my mind. i am glad to see that there are still channels focused on informing the viewers. not only that but really going deep on the subject matter. So for that alone, I thank you. I also want to thank you for the hard work you did in animating the video so that the complex things you were talking about had a very high quality visual aid, that helped immensely to allow what was being said to be comprehended and retained. The script was amazing also.
Words can't express the scale of knowledge in your videos. I use Starlink daily (heck this comment is being sent to you via Starlink at this moment) and now I understand more how all this is possible. It's incredible how this works and the labor of love you put on these explanations. Thank you.
❤
Exceptionally clear explanation of Phased array and QAM and the overall understanding of the Starlink data transfer is so easy to ingest. The voiceover and graphics are exceptional. Best technical video I have ever seen and I have been in IT for 50 years.
I am half way through watching, but I couldn't stop myself from thanking you for making such a video full of comprehensible knowledge!
Studying this in a course is one thing and seeing it with such a good animation of a real usecase is completely different thing. Thanks for making such videos, I am sure lot of effort goes into this.
But you may agree on that both course level work as well as this type of high level presentations are worth? One of my concerns is that my son wishes he could do away with university without realising that even E. Musk completed his undergraduate degrees in physics and economics. Good day
@@richardacevedo280 Don't get me wrong. If I have to choose one of them I will always go with University studies. This helped me recollect what l learnt, making me feel good.
@@muttarameshchandraprem1478 you cannot learn if you cannot visualize yourself in your head
@@richardacevedo280 I have a BA in Applied Math And a BS in Computer Science. I too am concerned with the discussion of limiting the math, science and arts to focus on just building electronic devices. The arts do more to push the math and science than anything. An education is a "total mental" experience!

As an electronics engineer familiar with this technology I am really impressed at the level of detail you go into with each aspect of the technology whilst maintaining an excellent level of clarity throughout.
These are seasoned engineers that have become real systems engineers.

@@richardacevedo280 you silly goose. We live under a Firmament that cannot be penetrated. NASA is SATANIC. Do not be Deceived
Absolutely agree with your comment.
Too good
In just 2 of your videos I have a level of understanding about electromagnetic waves and how it drives our most advanced technology than I ever thought was possible. I just assumed some concepts were beyond my ability to comprehend. Turns out the quality of the teacher is as important to our ability to learn as the amount of effort we put into it. I cant believe I understand this! Thanks for expanding my horizon!
It's been a while the days of 2.5Gcollular and first get WiFi when I learned the core concepts here as an engineer implementing this stuff, so I was super excited at how much you've just caught me up on current concepts like beam forming and 64QAM in under 30 minutes using an incredibly well explained approach (simplifying where helpful without omitting important information). My quickest subscribe ever! Amazing work. Thanks👍🏼
As a electronic graduate, I understand almost everything, it difficult to explain this complexity but the animation, simplest explanation of everything of how it works, you guys made this engineering a piece of cake..Your team really deserves appreciation.
I first encountered phase steering 40 years ago. It's amazing to see how far it's come.
Likewise the first 64QAM kit I used back then was a 7 foot tall 19 inch rack for 140Mb/s @ 12GHz terrestrial linking and only went 20km. 3 years later there were 7 of them in the same 7 foot tall rack
Each rack drew close to 3kW for 200mW transmit power
As an aside, audio modems used 64QAM for 33k6 and DSL uses hundreds of discrete 64 QAM carriers. The difference is the carrier frequency and symbol rate
That's pretty cool to hear about! During the research, I saw images of the early phased arrays and Lincoln Labs using dipole antennas. Pretty cool stuff indeed.
Could you transmit data modulating frequency, phase and amplitude? Then you'd be able to have a sort of 3D array of symbols!
@@SomeRandomPiggo phase modulation and frequency modulation are closely related. Frequency shift keying was the original method of modulating signals in most cases
The problem is that frequency modulation generates masses of sidebands and ends up being spectrally fairly inefficient (AM is inefficient from a power point of view)
@@miscbits6399 I see, quite often if an obvious idea seems good, its almost definitely been tried before

Scale is the answer
This feels like the old school Discovery channel, before it all became reality TV. Huge quality, simple to understand without the content being dumbed down, thanks for the great video
Extremely informative, enlightening and entertaining. Easy enough for a laymen like myself to understand but details are complete. I am in awe of the technology.
Mind blown.
Saw this video on Roku. Had to comment my appreciation for the research and work that went into this. Thank you.
Things we take for granted, are so complex and require lots of work and research. Im truly stunned by the working of this system as well as the animation and overall video. Detailed yet easy to understand and focusing on the required points. I thank each and everyone involved in making of this video, thanks for the information.
Thanks!! We appreciate it!
So true! and then we'll have people bitching about delays while posting a pic (give it some time. it goest to the space!). Or this service costing $$. This is astounding piece of work!

I was an electrical engineer a long time ago. It’s great to see some of the fundamentals of transmission lines and signal processing in a clear visual manner. Great work.
The amount of knowledge and design put into this tech just terrifies me in a sense that i understand how extremely complex each concepts presented/applied in here. This is literally human sorcery.
I worked on law enforcement radio equipment 20 years ago and thought I had a good grasp on most of the basics. This blew my mind!
I'm amazed by the high quality and detail presented in an incredible series of animations here. Good work guys.
@Science Revolution If you had any idea of how much nonsense you're telling you'd be ashame
Awesome Work On A Whole Top Beam Level.
i was a radar tech in the navy, this is an Excellent, Grade A explanation. top notch
I am amazed and blown away by the level of electronic technology as explained in this video. I had an intense interest in electronics since I was a boy - first, building a crystal radio from a kit and then many more from scratch for my friends. (they called me 'Brainwave') Later on I built many more electronic projects first with tubes and later with transistors. I grew up on a farm and was destined to be a farmer but my interest in electronics eventually led me to a career in mainframe computers starting in 1965. And of course, I built my first personal computer from a magazine article around 1975. Over the years I have gained a very good understanding of how radio and TV work, and the learned about computers from the ground up as I started my career as a field technician - installing and maintaining mainframe computers. So my understanding and knowledge of electronic technology now also included the digital realm. I am now 83 years old and many years retired and no longer in touch with the latest and greatest. So it was most rewarding to come across this video and the clear explanation of the workings of modern satellite technology. Thank you.
I also do not usually comment, but I needed to express how impressed I am by the depth and quality of your content. Too many other educational videos take specific technologies for face value and don’t go much deeper than surface level. I appreciate you digging into every process down to the electron level before moving on.
I think I would have done much better back in school if we had videos like this, as I'm a very visual person.
I can't even imagine how long it would take me to absorb all that information reading it in a book or listening to a teacher trying to explain it.
Thank you to all of you that contributed to this and other videos like it.
Educational systems everywhere- globally speaking, are absolute garbage dumpsterfires that are built on crooked groundworks with crooked understanding of knowledge and crooked misconceptions on what methods are best to relay this knowledge... Oh yeah, and they're also currently saturated to the brim with politics.
Stay away from them and question everything you ever "learned" if it came from a school.
Same here. A teacher could repeat the same thing over and over for a month and I would still have questions but show me a diagram and I'm done.
Can’t say how much we appreciate the quality of these videos ! Keep up . Great respect !
This is incredible. Thank you to the team involved for researching and creating this video
As a retired Navy engineer this was very informative and interesting. I worked on phased array 3D radar, so this was not entirely new. Although the technology is very advanced from my work in the 1980's, the basics are the same. This was done in such a professional manner with super graphics that one run through pretty much brought me up to speed. Super job, folks.

Well, that was my later years. I retired in '84. I started out on 55b tracking radar, but quickly saw that opting for a different school would be a good Idea. I went 48 while it was still young, about 1966, and then kept up with all the schools on the radar until my retirement. I was lucky to stay either a technician, or teacher, until the very end of my career when I made E8.
@@mm8ball So are we FC fam then, though? All my schools were in Dahlgren, and though that's mostly AEGIS central, iirc there were a couple of non-Aegis schools there. Feel like maybe something 48 adjacent was one of them. Something SSDS related maybe, idk.
You guys did an astonishing job here! From the amazing 3D animations, to the clarity of the detailed explanation.. Speechless... Bravi!
Elegantly explained. Thanks. Watching just once is enough if you have understanding of underlying subjects.
Thank you to all the staff behind the scenes who contributed to making excellent content.
I'm sitting here stunned by how well I learned how this technology worked. I don't just know, but I actually understand how the 64 QAM encoding works and in general, how digital information is encoded and like... what it looks like. I'm stunned. This is an incredible presentation.
This is all thanks to the behavior of light. So if our communication system gives life to your devices then what electromagnetic frequency encompasses your conscious? Probably the sun. Entanglement could be Entangled mind. You could really be in two places at once. As a wave in the corona of the sun and as a particle, which is partial, here on the earth.
Hold onto that! I don't know if you have a background in STEM but if not, this is a very strong indicator of your inclination towards it.
Hi
This is a fantastic explanation with an important level of detail that is left off so many other explanations. As an electrical engineer I could see this being useful in universities as an introduction to the topic to help give people a baseline understanding to build on. Great work 👍
How am I just now finding this channel. My heart breaks for my younger self. So great. Thank you!
This video is incredible! Really enjoy the animation's way of explaining sophisticated knowledge like how the phased array of antennae works! I took a lot of notes with the screenshots, learning has never been so vivid!
Amazing video. As an RF engineer who has designed satellite ground stations, this is by far the best video and training I have ever seen.
As soon as you mentioned phase shift, it immediately clicked to me how the steering would work. I was pretty proud of myself at the moment because I consider myself dumb. Thanks for all the effort and time spent on this great video.
Thank you!! Glad to help you recognize how smart you truly are!
This is now my favorite TH-cam channel. I am completely mesmerized by every video 🤯
An absolute masterpiece of ingenuity. This video's quality does it justice. Quickest subscribe even though I'm already subscribed to more channels than I watch regularly. My respect!!!
It's been a while since the days of 2.5G cellular and first gen WiFi when I learned the core concepts here as an engineer implementing this stuff, so I was super excited at how much you've just caught me up on current concepts like beam forming and 64QAM in under 30 minutes using an incredibly well explained approach (simplifying where helpful without omitting important information). My quickest subscribe ever! Amazing work. Thank you!
Your videos leave me absolutely speechless every time. You consistently explain and demonstrate complex concepts in very accessible terms, and with phenomenal visuals. The production quality is always fantastic and each video always proves to be well worth the wait.
This video was no different - as someone who has never quite understood the domain of electronics and wireless technologies, I found this content very interesting and really enjoyed watching it.
Great work as always!
Thank you tons!! The next set of videos will follow similar levels of depth, so we're excited to finish them up.
😅

I have no words to describe the quality and the depth of knowledge that this video provides! I wish I had such a source of material during my graduation.
This is most detailed and knowledgeable video I saw since my engineering… made me appreciate in awe the technology we take for granted .ll. Thank you for this great work
I am really impressed by the quality of animations and explanations. Big respect
Much Appreciated!
This channel is the only reason I'm not leaving TH-cam. The quality of the content is superb and visuals are unmatched.
Hello from Starlink space
As a retired radio engineer this is a fabulous production. Crystal clear explanation of the subscriber connection. Have you made one for the other connection ... Satellite to satellite and satellite to ground stations ? I'm subscribed for sure !!
The way they figured out how to form beams and do all of this blows my mind. It is also wild to be that we are constantly fighting each other as a species, but there are some amongst us that are so focused and intelligent that they’re pushing us forward into the future.
You think starlink isn't a weapon? 🤣😂🤣
Dude, get real. Don't even consider the cost of engineering this system, just go with the physical properties.
These are supposed to be used to bring internet to "under developed" (without internet) areas, right? Well "under developed " areas tend to not have a bunch of extra $ on their hands.
But before they could turn the first penny of profit they had to launch hundreds of these satellites into orbit. Then ship out a receiver dish to each individual customer.
How much do you think all those satellites and receivers cost? And that's all before getting the first customer.
And you think that's another business venture buly spaceman Elon? It never occurred to you that this whole idea could never even recoup the startup costs, let alone turn a profit?
You're watching this video, so obviously you have some interest in the starlink system. But that obvious flaw never crossed your radar?
So naive and trusting
This is a stunningly good explanation, huge thanks from this retired nerd! . Its amazing how simple and reliable SpaceX have made this highly complex technology to use. I know a few people here in NZ with Starlink, and it absolutely rocks for our relatively tiny rural population. One friend had his zero-techie wife unbox and set it up, and within 5 mins they had 250 Mbps. And even the US military were gobsmacked by how SpaceX managed to drop in 000's of terminals into the Ukraine military 2-3 days after the war broke out, and completely neutralise Russian's prior mega attack on the Ukrainians' Viasat satellite military comms system. The Ukraine military now have the world's best integrated comms system for weapons targeting and control, and Starlink is one of the key reasons (along with Ukrainian tech brilliance). The Russians also tried to radio-jam the Starlink terminals, but Starlink downloaded a patch to all terminals immediately to stop this jamming in its tracks. Starlink is now Ukraine's military backbone as well as providing wifi internet to 100,000+ Ukrainians in areas where the Russians have destroyed the mobile infrastructure. And, amazingly, these hugely complex terminals can all run off a 12V vehicle cigarette lighter.
The situation in the Ukraine is not of Russia's making. It is all down to NATO aggression which is led by the US and the UK. Agreements and commitments were not honoured by NATO. It takes brilliant minds to build this technology but it takes commonsense to stop us all getting killed and you people seem to be lacking in that.🌱
Yeah.. but not. This will not help the Ukrainian, Nazi authorities. You have no idea what signal jamming is. A patch alone can't fix it. For Russia, it does not cause any inconvenience, the presence of Starlink access points for Ukrainians. Ukrainians need this in many ways only to send fakes to the West. Each access point is a transceiver. If this transmitter is located in a special operation zone, it will be localized and destroyed. Over time, depending on legislative decisions, these access points will be taken away from the population, or deactivated.
Even tho it took forever, it was a super fun video to research because of just how impressively complex it is. I agree, it's soo awesome how this tech is helping out the Ukrainians defend their country. It's also crazy to think that this tech was designed by a fewer than 1000 engineers.
You need to reread history of Ukraine and check your propaganda sources. You will find that all of Zelenskyy's and Azov data is monitored.
@@BranchEducation you did a great job! Have you noticed the two panicked Russian trolls in my replies?😂
This is the best explanation I have ever seen in TH-cam, thank you so much for this.
Thanks! This was an absolute wonder of an answer to my questions! I’ll be watching many more.
Impressive. I am a long retired electronics engineer and found this video as clear and compelling an explanation of a complex system as one might find by a truly gifted instructor.
The videos on this channel have really allowed me to appreciate just how complex technology is and just how tiny and precise some of the things that hold up our lives are!
Great video, it’s been many years since I studied communication systems but your video helped give me the general big picture about how starlink works. Thanks
You guys are making difference in millions of lives.
Great video, right down to the antenna theory. James Maxwell applauds you :) I'm an RF design engineer and have been working with phase array antenna systems for the last 3 decades. Now days I do a lot of the beam steering control code. I'm passing your link on to some of my young coworkers, and others.
This is seriously the best engineering animation I have ever seen. I understood the basics of phased arrays but this is mind blowing. I wish I had learning resources like this as a young student. Thank you so much!
Excellent Video! I work in the modulation part of satcom but I never had a good explanation of how phased array works. Now I do! - Thanks!
So grateful that there are dedicated, brilliant people at BranchEducation making these educational videos. This is what I wish learning was like when I went to school. The future looks bright for education. Thank you.
Just found this video, and I'm blown away by the quality. I am an electrical engineer in this field and have worked on almost every aspect of what you guys have described in this video. Your animations do an amazing job of describing how some very complicated processes work in laymen terms. I am going to share this video with many people - thank you for what you do!
The creation of these animation must have been about as difficult as designing the actual Dishy. Amazing!
Remote cabin in Northern WI have Starlink last summer and worked great. No cable or Direct TV nonsense. Hook up with app and worked within a few minutes. Turn on and off when you leave. No ongoing charges. This is big.
Very nicely done.
As a former MPEG/DVB trainer, I can relate to the amount of work, bringing the complex subjects of satellite transmission, phased array antennas, beam forming, modulation accessible to a wider audience.
Very well done.
It is amazing how everything we take for granted is loaded with deep layers of systems, history and science. I can't wrap my head around everything that was explained but I am in awe of all the solutions brilliant engineers have come up with to solve these complex problems. And thanks to this channel, we get a peak behind the curtains. Truly astounding!
Amazingly simpler and clear explanation without skipping any of the important information's
Preparing for a job interview with Starlink, greatly appreciate this information. I will be sure to flaunt my newly acquired knowledge.
This is absolutely incredible. Wow, you guys deserve so much praise for all this research and work.. not only for this video but all of your videos are immaculate... thank you for providing this to us for free... without ads no less. I genuinely have no idea how you guys do this so well but just wow. You explain it so understandably.. I don't think there is a channel with anything near the quality and clarity as the videos you guys do. So yeah, all I can say is thank you very very much.
I have been using a StarLink system for about 6 months. I love it for speed but it does have brief outages during Zoom calls and streaming films. The video is truly amazing, incredible and Brilliant. The complexity of the concept and design of the StarLink is mind boggling. I've never seen such a well designed video explaining such a complex subject so well executed. Kudos to all involved. Thank you.
A truly marvelous tutorial explaining an elegant ensemble of beautifully coordinated engineering concepts. Thank you!😊
Most well spend 30mins of my life. This is astonishing and great thanks to Branch Education for bringing this content.
Some mindblowing moments right there! Especially how they redirect the beams without motors and the data transmission technique ❤
Wow!!! So clear and easily understood. As a retired professional developer of educational material, I have to give the developers 5 stars! Makes me want to go back to college for engineering. Thanks a million!
A big thanks to the creators. It was like revisiting 3 years on engineering studies within 25 mins, rather in a more lucid way.
You just made it all clear. I love the explanation on beamforming using the array. Mind blown.
