- This is a bonus project / display for Open Sauce 2024. I tried to make a scale (in distance, not size!) model of satellites in geostationary orbit. Just a quick demo of the actual distance to TV satellites, GOES, etc.

"Not great as a teacher' ??? Dude, youve taught me lots of things. Id say you are a dang fine teacher. Plus you keep it interesting....
I totally agree
Yeah this is where you're dead wrong. Probably the best teacher on youtube or the internet, who knows but you're in the top 5
I am a ham operator in Europe and since a few years we have access to a geostationary satellite. I am in the process of building a ground station to work via this satellite and yes, your demonstration was very very informative. Great job..
What satellite is this? The qo-100, or there is another one
It is qo100
Cool, where are you from?
I'm jealous of QO-100 over there! And you get a ton of stuff downloaded to Svalbard that folks in Northern Europe can overhear.
@@saveitforparts you should be jealous 😂😂.I think this satellite offers emergency channel and its telemetries are open to everyone. There is also a websdr that listen 24/7 to the QO100. I also listen to this satellite using a rtl-sdr v4 using an amplifier and a pcb antena
Cut the globe in half and 3d print an inner ring to connect both. That should make everything easier to construct in the first place and assemble/dissasemble.
Brilliant idea
You're on of the best teachers for this kind of thing! Glad you're going to Open Sauce!
A very cool video! Wish I could visit your exhibit booth. The fixed position of geostationary satellites explain why a dish has a different azimuth, elevation and skew in every location.
As you mentioned, a dish installed near the equator is pointing almost straight up, whereas a dish up in Northern Ontario (my area) is barely looking up at the sky.
You could make a clear plastic strip with coloured dots drawn on it matching your RT image along it to show the orbit that is long enough to overlap for about 95 degrees so it doesnt sag at the ends. So 6 equidistant punch holes.
I've actually always wanted to get a grasp on the scale of geostationary orbit - Neato!
How to get rod back thru? Use tape to attach thin flexible wire into rod before pulling rod out, and other way to assemble it back.
Outstanding sir.
This is top quality effort for both entertainment and education.
Awesome vid!! I've got an 8in globe that was given to me back in the mid 70's. It's still in great shape but due to smoker stains, it more resembles a post-Borg Earth. 😎👍
Awesome little project. Can't wait to see this tomorrow!
I agree with blue, you are a great communicator and teacher!
I had to pause the video at 6:54 and visualise the satellite pattern in a way my brain understands.
What I did was hold some pencils fanned out between my thumb and finger. if you have your eyes on the same plane as the pencils (standing at the equator) they are all in a straight line, but tilt the pencils up a bit to simulate being further from the equator then they turn into an arc. The same thing can be explained with the globe and rods but I think the closer the rods are the easier to explain it this way, its a bit hard with the 90 degree spacing. Also a bigger scale would help so you could actually put your head on the equator and look out at the sattelites but something simple people could hold up to their eye like the pencils works too.
Cheers for the video, sendin love from Australia!
I would have loved to go bigger with more satellites, but had to limit myself to what would fit in luggage and on the booth table. Maybe if it were hanging from the ceiling it could be bigger, that would be fun.
An interesting collection of globes. They explained the satellites very well. You would make a good teacher.
6:00 That looks like an MTV award.
This is a neat idea. It's kind of interesting to see it visualized because I've known the numeric distance in miles and kilometers but hadn't ever really fathomed how far geosync orbit is from the surface.
Thanks man! Hope you get sauced. Er something.
Maybe instead of a full 3d wire model, make a plexiglass disk with satellites laser etched on it. Add a 1/2 globe in the middle for perspective. It will be more rugged as well to ship. -73-
Very nice. Kinda want to replicate the model myself.
Such a simple concept, yet so interesting to see demonstrated in real life, good one
You choice of globe is Big Clive approved.
You could print out something for the table showing the inner and part of the outer Van Allen Radiation belt.
Years ago I did a diagram of this for a sci-fi RPG I was running, it hurt my brain a bit realizing how big/small things were. Best of luck at Open Sauce. (:
I love your satellite and ham radio stuff. And axman.
Could you add in a tiny motor to have the earth rotating slowly in unison with the satellites?
That would have been fun if I had more time!
@@saveitforparts I get it!
thank you
I would of loved to have a teacher like u
Binge watching your channel. Great work!
I had no idea about this, has crossed my mind but never looked it up. 😮
it doesn necessarily have to ocupy space inthe table, you can add a piep or rod let´s say 1 m between the stand and the globe, in table you will ocupy the sapce required for the stand and since it will be up in the air you will just use space in the air volume up from the table and it shall give you space for other things being very close to the stand
Hang it from the ceiling
Add a small motor
Looks like fun
Idea : cut them at 5cm from the "earth", then 3D print of find some tubing to reassemble that ? a bit of glue at opensauce will do the trick I guess
The c band and ku band sats are in what is called the Clarke belt. Named after auther c Clarke who predicted that satellites could be positioned there and stay
If you up to Open Sauce we definitely need a colab with Electroboom in your garage, Styropyro sending a 10 TW laser on a moon and receive it with rtl sdr or practical engineer on the sandland!
Your small geodesic dome you should make a Globe with it on a pedestal. 😊
awesome stuff and very interesting and informative big thumbs up 👍😃👍
I’m so glad that I went
Hope you had fun! We really enjoyed it. I'll try to do a video on it when I get caught up on all my emails and comments and whatnot!
It would be great to have the Moon on there too, so people get an even better idea of scale.
Know what's cool? When I click on a video because it looks interesting to discover it's saveitforparts.
A photo of the rings of Saturn also show how geostationary orbits look curved.
I'm not sure those are in geostationary orbit, I thought the rings moved at various speeds relative to the planet's rotation? I'll have to look that up now :-)
@@saveitforparts correct, they aren’t geostationary, but they are on an equatorial orbit.
The shape would be right and most people have seen a photo of the rings at a low angle.
I remember seeing satellite dishes in Fairbanks and the surrounding areas look like they were pointed almost at the ground.
Yep, way far North for geostationary use! I think some of the big ones like UAF's Geophysical Institute or the NASA station at Fox would also point low when not in use, so the didn't collect snow.
You can make a glomobile with the left over globes
"not great as an educator" really? you do a great job with your videos and making such models to show people these concepts is a really good method (only a few people can build a mental model in their head easily.
I head disussion with a couple kids in school about the ISS the moon, satelites etc. I already thought about how to give them an idea of what is where (the planets) by, maybe having them stand in scaled distance to each other but maybe preparing a globe that way would be a great addon and you could have a moon at the end of the room as a bonus. I might 'steal' your idea ;)
Since I have no radio telescope (yet) may I use the picture of the geostationary satellites you created, I guess this would make a great story that someone took it with a bunch of parts he hacked together showing you dont need being a huge organisation to explore this area of our world.
Here's a fun argument: One satellite is launched in the usual manner and eventually reaches a geostationary position. Another satellite is gently lifted by a space elevator winch (which is itself geostationary) and is carefully placed right beside the first satellite; it never exceeds 5 kmh during the entire process. Will the 2nd satellite happily stay in place?
Had a huge argument about this years ago. I know the correct answer.
5kmh relative to what? Missing that detail makes your question unnecessarily confusing, from an orbital mechanics POV it's actually impossible because it's never doing less than 5kmh while it's still unrefined rocks before it's even manufactured. If you say the surface of the earth below it's final orbit is zero, it's vertical velocity is slow, but it's horizontal acceleration is huge very quickly. Sorry mate, it's not a great question IMO.
@@rubikmonat6589 Earth reference of course (didn't think that that would even be a question). Sat 2 never exceeds 5 kmh during the space elevator winch process, straight up gently on a fixed rail. No sideways at all, which is precisely the crux of the entire "argument". Carry on...
I vote weird multiverse planetary system for the extra globes
Had a guy come by the booth and discuss alternate dimensional TH-cam with me for a while, couldn't tell if he was an alien or not :-)
I absolutely need that satellite 3d model, do you have a link?
Do any of the other globes fit the size of Venus and mars?
It might be interesting to put them down the street to show how far away they are
Wonder if you could put the smaller globe in the middle of a bigger clear sphere, and put the global satellites on the inner surface of the clear sphere?
That would be cool! Good idea!
And please make video of your booth at open sauce
Yup, that's durpy if i've ever seen one.
What is the scale ratio of your model?
Talking about drawing to scale, 99.9% of people can't draw a true to scale picture of the Earth and Moon. The simplest way to draw it to scale is, take a sheet of standard printer paper and turn it landscape. In the top left corner draw a 10mm circle to represent Earth. In the lower right corner draw a 2.5mm circle representing the moon and that's it.
Most people don't believe it when you show it to them, cause school's general science books could never illustrate them correctly to scale on the same page.
US-Letter or DIN A4?
Depending how long the table is, a moon to scale could be fun.
@@NotaBurnerac-iv6ppI assume a global standard page, since they used mm. Not USA going through a rebellious phase page. 😊
@@rubikmonat6589 Using stickers, all you need is your Earth sticker and your moon sticker and enough room to be able to fit them and 30 Earth diameters between them. So you'll need a table 32 Earth sticker diameters long. for example, if your Earth sticker is 6in diameter and your moon sticker is 1.5in diameter, you'll need a table that's 192in long.
Maybe something more of a mobile hanging from above?
one minute ago gang rise up
Just my suggestion, but do your presentation like you do you TH-cam videos. Everyone there are people just like you and your TH-cam audience. So do not look down on yourself, but just tell the people what you know and have learned.
Can you do a video in Ham Sat
you said rod lol
I left Open Sauce with one of these satellites. It totally wasn't intentional. 😉
JK Lol 😂
Honestly I'm surprised more didn't break! I think we gave away one astronaut at the end :-)
Glad you only have a globe problem not a GLOBAL problem 😂
Can I have one Potato cannon pis
درود برشما مهندس عزیز اگر امکان دارد زیر نویس فارسی بزارید .من از برنامه شما استفاده میکنم سپاس🙏🙏❤❤❤❤❤❤❤❤👍
I get why you might use miles for everyday stuff that a viewer might have a frame of reference for. But when you are talking about astronomical figures, there is no benefit to using miles over the units used by the entire scientific community. Nobody can visualize eight thousand miles. Nobody's like, "Ok, that's three times grandpa's driveway at the farm." Just use frigging metric.
Maybe it's more suitable for his channel demographic? I agree use metric for anything that isn't related to north American grandpa's farm.
@@rubikmonat6589 But, it's not, that's my point. There does not exist a demographic that works with figures like 28,000 miles and has an easier time visualizing that than 45,000 km. The problem with visualizing that distance isn't the units being used! So just use the units that the audience will find used if they choose to learn more in the future.
The stationary satellites in orbit are also known as Clarks belt named after Arthur C. Clarke.
Arthur C. Clarke. After the crest of World War II, from his base in Stratford-on-Avon, England, a young officer in the Royal Air Force, Arthur C. Clarke, who dabbled in science fiction writing, floated the idea of global communications satellites in a 1945 letter to the publication Wireless World.🛰🛰🛰🛰🛰📡📡📡📡📡📡
