How to Build a Radio Telescope (See Satellites 35,000km Away!)

Over the last 2 months me and my friend Artem (you met him in the last video) built our first radio telescope. It was built mostly out of off the shelf components, like a satellite dish and Ku band LNB, as well as some parts we 3d printed. When all was said and done we had a system that could not only take images of the sky in radip frequencies (in this case 10-12ghz), but could also be used to track satellites. With it, we were able to see the ring of satellites in geosynchronous orbit, over 35,000km away, This is only the first of what I suspect will be many more telescopes like this. Next time we'll be building ones that are far larger and can see things like the hydrogen lines so we can image the milky way.

I make my living as an Electrical Engineer, specializing in microwave radio systems, and I'm an amateur astronomer. I mention all of this because it's the only way I know to describe how crazy hungry I am for videos like this one, and how I gulp it down when I find one. This video is an absolute delight ! My hat is enthusiastically off to you guys. Now, please permit me some criticism that I hope you'll find constructive: Please give some more consideration to the question of what your finished video is to be. Is it to be a demonstration of what you did, how you did it, how much fun you had doing it, how gratifying your results were, and how the viewer can use some of your great innovative ideas ? Or is it to be an operetta, with some catchy tunes in the foreground and some occasionally intelligible murmuring in the background ? Why do radio commercials or RU-vid technical videos need music at all ? And if music will be used to set a mood, then please don't use 6 to 10dB more music than it takes to set the mood. The verbal description is the priority here. Until you can either dramatize the script with sufficient skill to make all the details stand out from the background, or else hire a professional voice to do it, please highlight the priority content, and put the background back in the background. Back off on the music. We want to hear everything you have to say.

@thethoughtemporium 6 лет назад

I'm glad you liked the video :) As to the sound/music, the issue is that I mix the videos on a professional set of headphones and so it's really inconsistent how other people hear it. I can hear everything perfectly fine on my end, but on some sets of speakers it's much harder to hear. Because of that I've adjusted how I put the videos together and you'll notice that in new videos there's either no music, or it's much quieter.

@Alcohen2006 6 лет назад

The Thought Emporium Good ! Thanks for the reply. Reading more comments, I see that I wasn't the only one, so I know you've gotten the message. This is the first of your videos that I've seen.

i did not see building a radio telescope, this was building a mount for a radio telescope. a lot of info was lacking. how do you connect it to your computer , the software to use, decoding the frequencies from the dish etc. the video did not reflect the title. it looked cool when i first watched it and wanted to build my own. but now i watch it again , it just shows a complete radio telescope being mounted only.

@daniwalmsley611 3 года назад

You don't need a bigger dish, you need more dishes. You can increase the angular resolution of radio telescopes by pointing two or more at the same object and measuring the distance between them. The images can then be combined like stacking exposures with optical telescopes. The larger the distance between the dishes and the higher accuracy in the measurements improve the angular resolution. This is how we took the picture of a black hole. By combining radio telescopes from all around the world with accurate positioning we were able to have the angular resolution of a dish the size of the earth

Great job! I'm building something similar originally for solar tracking the sun. I made some 3D printed worm drives that have a very high torque and need no holding current for the steppers. As a result, they have microradian accuracy which is way overkill for solar tracking, but it can also do astrophotography, satellite tracking and radio astronomy just by changing what is mounted on it.

@brockam Год назад

The ionosphere of Jupiter can give you some interesting results. I believe you can use an old television yagi antenna to monitor the noise storms from there when the Sun is being active. EME stuff is super cool too. There are digital transmission protocols that HAM operators use that have excellent copy right at the noise floor. The software used for those is freeware, and you could use a computer soundcard to interface with a radio to transmit and receive, or maybe more accurately to encode and decode... your radio and antenna would be doing the transmitting and receiving.

The simplest radio telescope is just the dish and the satellite finder. As you move it around, the sat finder will only make noise if you're pointed at the sun or one of the satellites. It's a really simple demonstration I think your students will like :) All the motorized bits were just because we wanted to make an image. I'll upload all the 3d models on thing verse or something.

@jameselger572 4 года назад

Hello, try a noise cancelling antenna! Here's how it works, it uses two antenna. One sits in the focal shadow of the receiving cone. One antenna faces the dish, and accepts focused RF. The second antenna catches all that local radio noise astronomers hate, a straight antenna behind the focal plane a ground plane separates focused from noise by geometry, on the parabolic side is the focused from space receiving antenna. Now, we just use plain old phase, keep track, and build a operational amplifier to eliminate unfocused noise by means of common mode rejection. It is the same as noise cancelling head phones but, all RF. Have fun! The next phase, dual equalizer input op amp variable gain stages. You can amplify until you hear the atoms the transistors, we the use a variable notch filter to cancel it out before it's distorted by cut off or saturation, and continue until the motion of one electron, equals 1 watt, or 6 to the 28th power of ten .

@jameselger572 4 года назад

How to get rid of noise. Next, power levels, long exposures, and the search for common denominators due to photon scattering destroying signal data over great distances to find units of measure, and hidden base n features. Like finding signals in powers of ten, or six because, they only have a total of six fingers....

@jameselger572 4 года назад

Switch to an telescope's calibrated movement, or calibrate yours so that if you find something, you can tell other astronomers where to look.

@jameselger572 4 года назад

The only lenses you get are amplifiers...

@jameselger572 4 года назад

You'll be fighting 60 Hertz all the way. I did build amplifier with that kind of gain, and every stage or two, I had to us a notch filter to put the 60 Hertz on both inputs and the whole signal, on only one input. Recursively using common mode rejection.
