I recently applied for training at a company that specializes in satellite attitude control systems. This video was highly informative, and I can't wait to further my knowledge in this field. I also wanted to thank you for how incredibly helpful your channel has been throughout my student life. Studying engineering has been made much easier with resources like yours. Thank you!🇿🇦
Right. Controlling satellite attitude is especially important when things gets moody up there. They might need a good therapist to keep them from spinning out of control. I'm taking a degree in psychology myself :)
What is range of construction cost of average satellite? Like the ones used for earth imaginary (google maps, airbus data) and telecom. how many of satellites are used for such things? what is average assembly and design time for one?
This video is very impressive! I worked in the aerospace industry for 37 years including a number of years helping to develop an attitude measurement system for satellites. This video accurately describes all the high points of the engineering challenges that we faced in our development program. VERY nicely done!
You still need college classes to actually understand the science and math mentioned in this video, not to mention building a satellite requires dozens of people completing years of college education.
"Perfect quality" that what i was saying so many times when watching this vidéo. A content of an entier Book in 30 minutes and not illustrations but animations !!!!!! Thanks for this wonderful job.
I work in satops and this would be a great intro for people who haven't done an aerospace degree(or two). It covers the basics but in a very subtle way poses questions. A good resource!
it's cool how your videos actually help students to understand some subjects but are also easy to understand for curious people who are not specialised ! well done !
This might be the most concise explanation of satellite design I've ever seen. I would like to add this to my "new hire guide" for employees who come help me build satellites.
As CubeSat designer, this is a breeze to watch. Kudos for the details and getting all the animation details right including terminology, units and order of magnitude for numbers. Watched it on Nebula but they don't do comments so here it goes!
I worked in satellite solar array and mechanisims engineering as a design engineer for four years and this video is awsome. I wish i had it when i first started!
From a very newbie in satellite mecha design, this video is just...Awesome!!! I have no word to explain but thank you so much for working hard and sharing.
Nice video! I used to work in rad-hard electronics and its crazy how important it is to rad-hard your components, sub-system, and once you have that put together test the whole computer system. Looking at you starlink 👀. In my basic understanding, satellite design is not to design to prevent complete failure from radiation, its to design around it. The electronics degrade over time and normally designers will put multiple circuits in and will rotate them out after a defined amount of time. Semiconductors degrade much faster when they are energised vs when turned off in rad environments.
Did you know that all of SpaceX's original electronics came from Digikey? That is UNTIL they started flying payloads for NASA. Then they were required to use rad-hard parts. I wonder WHY the astronauts onboard the ISS can still use iPods and Apple Laptops?
@@stuartgray5877 Digikey sells rad-hard components too. Also, the ISS exterior already has significant radiation shielding. If it can protect humans, it can probably protect your electronics too. I'm guessing any critical devices will be hardened, but someone's iPod failing is far from mission-critical. It's also a whole lot cheaper to replace a non-critical (or backed-up) iPod or laptop than it is to have a team of engineers design a rad-hard version.
@@Snookers_ I know all that. SpaceX was using non-rad hard parts at first. They even asked me what I thought of that when they interviewed me for a job on Dragon Avionics. I said the the same thing I said above: NASA won't let you you Keep doing that for manned missions. I was correct. They offered me the job but I turned it down. I'm too expensive for them I'll be kicking myself once they go public as the signing bonus was a LOT of shares. I was told by a colleague that went there they work a LOT of OT without pay. I'm too old for that.
@@stuartgray5877 Ahh, I definitely misinterpreted your original comment. I've heard a lot of people talk about their experiences working at SpaceX and it all seems to be pretty similar - lots of unpaid overtime, and lots of half-regrets from people leaving when they did. I've also heard a few other very interesting stories regarding SpaceX that I probably wouldn't have believed if I didn't have absolute trust in the person they came from...
I was looking for a video on a satellite thermal management system and ended up watching this video. This is one of the best to understand thermal management systems and overall other systems in a satellite control. Thank you for the wonderful video.
This video reminded me of my first internship where I got to built a cubesat and really provides a basic overview about the main things about satellites. However, I would like to add one thing at 12:12 . When reaction wheels reach their saturation, it does not mean they cannot be used anymore. If they are played in a coil, their rotational energy can be converted into electrical energy which will slow the reaction wheels down, while also providing power to the satellite.
ಪ್ರತಿ ವೀಡಿಯೊದಲ್ಲಿ, ವಿವರಣೆಗಳು ಚೆನ್ನಾಗಿವೆ. ಇದನ್ನು ತರುವ ನಿಮ್ಮ ಪ್ರಯತ್ನಗಳಿಗಾಗಿ ನಾನು ಪ್ರಶಂಸಿಸುತ್ತೇನೆ ಮತ್ತು ಧನ್ಯವಾದಗಳು. In every video, the illustrations and explanations are good. I appreciate and thank you for your efforts in bringing this.
Amazing video. Beautiful visuals that add to the audio. I got Nebula partially because of you, even though I end up watching most things on here anyway. Good luck with your next video.
Excellent lecture with precise descriptions and awesome visuals that I have so far come across ... after many years being in Indian Satellite Industry. Congratulations. 🌈 Really Efficient Engineer the presenter.
Thank you so much sir for this video.. I aspire to be an aeronautical engineer. This has helped expand my understanding of satellites. This has added you a subscriber as well.
Ok, wow. For decades, I’ve been unclear about antennae gain, incorrectly equivocating it to amplifier gain, therefore not getting it. But a simple animation about an isotropic antenna next to a specialized one - eureka - I can finally conceptualize the principle and move on. Thanks.
I work in the aerospace industry, and these models and animations are quite close to real components. Great job. Should've included phase array antenna for transmission system. They are amazing ..
lol what the hell bro, you are humiliating the whole education industry with these videos of yours.What in the holy clarity is this??!Never have I ever seen anything explained so beautifully and concisely. Can you please do more videos on RF and Antenna propagation. Thanks and I hope you thrive and grow even more.
Im in my 30s and got sick of beeing a car technichian and mechanic. a very very high end sought after job opened up not far from me. its a tech/mechanic for satelites.. 2 intervjues later and im crossing my fingers i get the job.. really. that would be to build wire harness, printcards and ecu`s, welding and so on for satelites.... im sooooo hoping i get the job!!! i want the job!! loved this video. makes me more prepared for whats to come if i get lucky enough to get the job.
Awesome video, especially the visualization of radiation pattern of directional antennas with these flying arrows :) 8:56 - sorry for nitpicking, but are accelerometers useful onboard a satellite, especially if it doesn't have any propulsion, only attitude control? The accelerometers will always show zero.
This is an very beautifully done video I'm an big fan of engineering in space and all the cool stuff we build. Watching this video is making me second guess my decision of leaving engineering 😅
As a Satellite Systems Engineer myself, I can confirm this is the best explaination one can have in 27 mins. KUDOS.
How did you become one?
@@prathameshmore4739 Wow - Amazing, do you like your job as a satellite systems engineer?

I work on satellites and this could honestly be a great intro video to show someone for an internship.
I am finishing an internship working on satellites and i can confirm i wish i saw this 12 weeks ago lol
oh wait a minute hey yuri lmao
As a Junior in my aerospace engineering degree, whose looking for an internship, this was a really great video :D
Hello Dr. Yuri. I am a space enthusiastic intern at a space tech uni, could you help guide me build a satellite?
What is range of construction cost of average satellite? Like the ones used for earth imaginary (google maps, airbus data) and telecom.
how many of satellites are used for such things?
what is average assembly and design time for one?

The efficient engineer videos are far better than college classes.
These videos are a COMPLIMENT to college classes, not better. This is a very harmful and damaging sentiment.
They're not even comparable. You go to college for a degree. You watch a video for a quick overview.
You still need college classes to actually understand the science and math mentioned in this video, not to mention building a satellite requires dozens of people completing years of college education.
Do know the formulas for these systems?
Not even close mate, this is like 9th grade science at most
"Perfect quality" that what i was saying so many times when watching this vidéo. A content of an entier Book in 30 minutes and not illustrations but animations !!!!!! Thanks for this wonderful job.
Do you have any idea what program has been used in this video to create these animations?
I work in satops and this would be a great intro for people who haven't done an aerospace degree(or two). It covers the basics but in a very subtle way poses questions. A good resource!

This is absolutely beautiful animation. As an engineer myself, I am chuffed to bits with this one.
Good job. This taught more than school did on the subject.
This might be the most concise explanation of satellite design I've ever seen. I would like to add this to my "new hire guide" for employees who come help me build satellites.

very well explained for beginners
Love these videos
now this is how one is supposed to nail a video
I laughed at this video heading. If you could put a " thought" in low orbit, it's considered a satellite.
What a beautiful video.

Can you please make the video on welding......your contents are really amazing 😍
I love his videos. So cool
We need a tutorial like this one but for the oscelscope please❤
Thank you very much my friend
Nice one 💯👍
Please do a video on plate theory, electric propulsion, chemical propulsion, or deployable structures.
So awesome ✨
As a satellite I can confirm that this is the best explanation
Interessant Satellites within Power Control
I felt happy just by looking at the video length, even before watching the video
I need to know more because I want to help others and make progress
