- Satellites are expensive and big and only can be launched by the military, governments, or large corporations. Tomorrow morning, this will change. A 16-year old student and his team will launch a LoRa satellite: FossaSat-1
This is Julian Fernandez with his satellite. His company is called Fossa, an acronym for Free Open Source Software and Aerospace Systems, and his first satellite is, of course, called: Sat-1. According to the plans, it will be launched tomorrow, Friday 6th, 7:56 UTC. It will be on board of an Electron from Rocketlabs, a small rocket which is 12 tons and 17m long. It is optimized for small satellites and will start from New Zealand

6th of December is the launch, not November...
Andreas can u give advise on making some passive income from youtube how could you do that and i am a student . If u read please help me by giving me some advice i watch almost all of your videos regularly please help me,sir.
@@jonneycon6157 gross.
@@cannaroe1213 what ??
@@jonneycon6157, CannaRoe is indicating that your request is inappropriate and I concur with his assessment. If you want to see the revenue opportunities etc go look at EEVblog (Dave Jones) who lays out the revenue opportunities exactly. The likely answer is that you won't be able to support yourself. It's hard work, takes a lot of time, and has to be done for love of the topic first.
Thanks for the info. All the old date information out there is confusion.
One more question is what type of orbit will it have?
This is a great step for Lora and its exploration . Hope for the best for FOSSA project. Thanks for the info and for the student.
You are welcome!
This is a really impressive achievement - especially at 16 yrs of age!
I agree!
I am a licensed ham (amateur) radio operator... Ready for the launch. Have the equipment and proper antenna ready. Thanks for keep this topic fresh an alive.
So I assume you watched also the Sunday's video...
@@AndreasSpiess yes I did. I am a bit disappointed. Hopes are good.
I have so many questions! What a great project. Hopefully the folks at LoRaWAN are watching and see the value of a relay....
Just watched the launch. Very professional. Thank you for telling us about this Andreas.
You are welcome!
Amazing world we live in. Best wishes for everyone involved in this project.
You are right. And thank you!
Thank you for exposing this to us Andreas. So often I hear about these happenings, after the fact. Congratulations and best of luck to this young man and his team tomorrow!
I met Julian in the UK at a LoRa event an decided this is an interesting story...
@@AndreasSpiess it is a great story. Every science teacher in America should be looking for stories like this AND sharing them along with following up. You're helping that happen. Thank you again.
I’m very excited about this project! Looking forward to seeing the updates!
Delivered ;-)
Great information again Andreas!!! You are such a great teacher and inventor.... and now we can go to SPACE!!! Wonderful! Thank you again!
You are welcome! No Ground Station in the USA so far ;-)
@@AndreasSpiess So USA citizens can't communicate with this satellite?
No. We should have a few US guys building a ground station to participate ;-)
Thank you for the video Andreas, that is really exciting. I wonder what can this might lead to if it operates successfully. Looking forward to your next video.
We will see. First it has to work...
Thanks Uncle Andreas for another exciting and inspirational video! 😎🐱🏍🛰
Good Luck to Julian!
:-)
Good to know ! Thanks for sharing !
You are welcome!
Thank you Andreas for the announcement. I am really curious if one can actually establish communication via this satellite. Looking forward to your video regarding this.
Me too. Also what effect the doppler effect will have to the communication...
@@AndreasSpiess that needs arrow antenna we amateur Radio operators use to catch the birds.. Doppler frequency shift can be programmed into your hand held or base VHF/UHF station as channels and can be switched according to the rise and fa of the satellite pass..
You can ask any ham operator for a free demo.
@@AndreasSpiess LoRa shall be immune to Doppler shift. BTW: look at miromico.ch/lacuna-space-collab/
@@AndreasSpiess It looks like they go for 125kHz bandwidth, so locking the signal should work fine. But it will be interesting how LoRa handles possible fading during the transmission. Looking forward to listening for the sat :)
@@AndreasSpiess by coincidence I did a study whether the Doppler from a LEO satellite trajectory is a problem for LoRa, turns out for most settings it is not. A company together with ESA already launched a satellite with LoRa technology some time ago. They tweeted the communications, unfortunately the tweets were deleted.
I will keep my fingers crossed for this. I'm also keenly waiting for the first Earth-Moon-Earth LoRa transmission :D
That should be possible if you find somebody with big antennas...
Wow! I wonder how much it is to launch one of those Pocket Cubes. I remember seeing once that a "full size" 10x10x10cm CubeSat was some US$10,000 launched. Wonder if the modern-day space race has lowered that price any.
According his croudfounding campaign he needs 30000 Euros
Great video. Really exciting news.
True!
Wouw! This looks really fun to setup at home, thanks for the information! I hope you make a video tutorial about targeted for totally beginners like me :-) I'm currently trying to get the overpass times of the ISS for my location working in combination with LED's Thanks again and keep on making the video's, for me as a beginner they are very welcome!
This channel is not focused on beginners. So it might need some stamina from your side. The results, however, are rewarding...
Andreas, vielen Dank für die Info!
Das ist so cool!!!
Bitte, gern geschehen.
அருமையான முயற்சி !!!!
நான் ஒப்புக்கொள்கிறேன்
Thanks for drawing attention to yet another fascinating project. I already have the hardware (and am licenced) so might have a look at this.
Can you do a video on manufacturing extra time to do all this good stuff! Can I buy extra time on AliExpress?
I could not immediately find info on planned orbital parameters? I assume orbit will be quite low so passes will be short.
The Orbit will be low (minimal 300km) I will be published after the successful launch. I am curious how Doppler will influence LoRa...
@@AndreasSpiess Yes agree, doppler situation is interesting. They seem to be using 125khz bandwidth sf11.
I see on their Github there is software for a simulator. With the short pass time this could be useful to verify the basic operation of the ground station in advance.
Hi @acomz, I have a good friend in AliExpress and he tells me that "Extra time" is out of stock with no date for replenishment... Really sorry.
Acomz
So you’re not looking for quality time then?
@@AndreasSpiess We did a bunch of studies on Doppler. Will work fine with SX1268T modules with TCXO modules, standard crystals ara a mystery yet
Amazing!
Yes!
Thank you for making this very informative video!
Is it possible to operate on the required 436.7 Mhz frequency, with the aforementioned TTGO 433MHz Board?
Should I go ahead with the purchase or some extra modules will be required?
Maybe you go to the telegram group. There are problems with the satellite.
Grüezi aus New Zealand!
So you are close to the "action" tomorrow morning ;-)
@@AndreasSpiess It's already Friday almost midday here. Fairly close, I'm in Wellington about 330 km from the launch site.
Kia ora from the Waikato (about 400km from Mania). Only an hour til launch :)
Morning Andreas, have a wonderful day mate. I am a ham from Victoria Australia if they need help.
Thank you for offering your help!
Oooooooooooh that's sooooo coool!
:-)
Great Video Andreas. Do you know more about the orbit of this satellite?
I assume you watched the today's video.
Awesome!!! Now us hobbyists will have access to a satellite!!! 😁
Radio Amateurs have built and launched many many satellites (over 100 of them) that hobbyists with the appropriate license can use.
These range from small cubesats like this one up to a payload as part of a geostationary television satellite above Africa covering 1/3 of the world between Brazil and Thailand.
And best of it: equipment for such communication becomes cheaper all the time, due to developments in SDR and microwave semiconductor technology.
Awesomeness!!!!
It sounds like a good idea for a radio ham like me who’s interested in experimenting with contacts to low orbit satellites. If we think ahead of how that principle could work for all LORA Systems over the world and 24/7 we probably need dozens or hundreds of them.
On the other hand this/those satellites will be just some more of them uncontrollable bits of debris orbiting our planet, soon. Or is there a way to remove the satellites from their orbits safely and without any residue?
You are right of course with the debris. Everything has advantages and disadvantages :-(
Pa sixty6 the way you remove cube sats from orbit is to plan the orbital altitude so that the time it takes to decay is a bit longer than you want to use it for.
Would be nice to have one in geostationary orbit, but think we need to wait a while longer for that kind of thing.
We have one there thanks to Quatar. But you need big antennas for that one.
@@AndreasSpiess Not really that big. A 50-60cm satellite dish will do it. The smaller the dish the more TX power you will need.
So many questions! I assume you will need a quarter wave dish or something to be able to get a signal?
I do not think. LoRa has a very high link budget. I assume a normal antenna should be ok. But time will tell...
Nope, Monopole will suffice!
@@FossaSystems that is outstanding, bordering on witchcraft :)
3d printed, and electric power pumps, and first aprouch to returning first stage to earth. Interesting rocket.
The return was successful, they said.
bang! goes your distance record Andreas!
This one is not surface-surface ;-)
i have watch many stream rocket launches, and many off electrons they are reliable
Good to know.
No way ..fair play to the guy legendary
???
@@AndreasSpiess the guy launching a satellite is a legend
Thanks!
Great news sir
:-)
Maybe they can pair with the things network project, and have world coverage in the future.
How much extra energy does it cost compared to sending a signal to a local Lora tower?
If the thing works you should be able to use normal LoRa boards and antennas.
So am I right in thinking because the frequency is in the ham radio space and that it works as a relay you would have to operate a node and gateway seperately to the normally 433 or 868 deployment? And would need a ham licence
Up and downlink are on the same frequency.
Having worked satellites I'm curious how the ground based modules will handle doppler shift.
Me to...
@@AndreasSpiess It would be rather embarrassing if they missed that vital little detail with physics. There is nothing in the LoRA spec for doppler shift so you'd need to wait until the speed into or out of the line of sight is near zero, basically the midpoint of visibility.
Just a minor question : you meant 6 of December right ? 😅👍
Yes, you are right! I pinned a correction to the comments
Can you make a video about that sattelites with some technical details like how that sattelite sent and recived data from earth ground station like you made? And what radio component and antenas are used on that sattelite?please🙃
I am no specialist in those topics. I did a series where I built a ground station for a geostationary satellite (QO-100) and videos about TinyGS, where I show how to build a receiver for the small LoRa satellites.
@@AndreasSpiess yes, i've watched them all, but i am interested on sattelite technology, specially the antenna and radio part, anyway thanks for those ground station videos🤩😍
Makers may take a look at the DRF1268T from DORJI. I am starting work on my own PCB.
Julian uses this module on his ground station
How exciting
Yes!
A small propulsion from a teenager, a giant leap for LoRa. And the best part is they use 436mhz rather than 868mhz. hopefully, TTN will "officially" support 433mhz one day. Waiting for the sunday video.
This project is not LoRaWAN compatible for the moment...
Do a video series about some of the HAM license theory! I know the laws differ between countries, but I'm sure all the theory is the same.
AFAIK David Casler does this: th-cam.com/users/davecasler
Thank you very much Andreas, I feel very proud of Julian, Andalusian like me.
It seems he is half Swiss, too ;-) So we are two proud persons.
Andreas Spiess, Wirklich? Ich wusste es nicht, er wurde in La Línea (Cádiz) geboren und studierte in Madrid.
Welche Verbindung hat er zur Schweiz?
Seine Mutter vielleicht?
Du musst ihn selbst fragen. Er hat es mir gegenüber erwähnt.
Egal, es ist wichtig, dass junge Menschen sich diesen Herausforderungen stellen. Vielen Dank für Ihre Aufmerksamkeit.
Looking forward. What is the orbit of the sat? And the footprint?
73 de 4S6TMP
This will be published when it is up and stable AFAIK. It is low orbit.
TLE's to be published soon or on our twitter @FossaSys
Thank you @@@FossaSystems. Will stay in touch.
👍👍👍
:-)
I wonder the reasons for using non 433 & 915mhz bands ? Was this just to limit the amount of potential traffic or other reasons ?
Guessing there's a lot of earth bound traffic on those free frequencies, would make it harder to hear a fainter signal. I guess they chose something close so you could theoretically still use off the shelf lora transmitters, maybe with some different antenna tuning.
Guessing Power. To hit a satellite would take more than the few mW an unlicensed user in the ISM is allowed, so move to a licensed band (nearby) and let licensed operators use their licensed power budget to reach the dinky cube :)
@@SittingDuc Thanks for that, what orbit elevation is the sat going to have I wonder ?
Sir, can we cube satellites remain stationary in the Leo orbit 📡🌍
No. Only geostationary satellites can do that.
what kind of ITU licensing is required for 436.7Mhz
You need a Amateur radio license
Did Launch Happened
Yes. But the satellite never properly worked.
didnt know new zeeland had rocket launches, but then i havent check if they had.
It was also new for me...
I am very interested in this project, I will order some modules and make a start over the winter - i am sure my UK Amateur radio licence will help :) 73 M0XXQ
The license is always good. Hopefully the rest will also work...
hello,nice video,,new friend
Thank you
looking forward to do some tests.

After the today's video you should have the info to do so.
Satalites are big, shows a space ship without anything for size reference
The satellites are only a few cm big
Hi
Hi, I am very interested in buying some products.
I got an opportunity to set up a LORA lab in my organization which works for nanosatellites.
Could you please give me the list of equipments with the cost to buy a basic set up for LORA in nanosatellites application?
It will be much appreciated.
I M a TH-camr and not a consultant ;-)
I want to do same please guide
Maybe you ask FossaSat. I am not involved.
He will probably regret he named his company starting with "Free" in The Future
I do not know his plans...
73, 51 - TKS
You are welcome!
I'm interested! I'm a ham and I'll help anybody in central Arizona. Cheers! Chris - NI7I
Thank you for offering your help! I think those are the projects which keep also Ham radio interesting for young people...
Ich habe einen Traum für das Donaudelta. Vielleicht träumen wir zusammen. Keine Ahnung ob es realistisch ist. Idee bleibt Bewegungssensoren im Donaudelta zu plazieren. Datenabfrage war angedacht einmal am Tag eine Drone aufsteigen zu lassen und Bewegungsdaten von Tieren oder der Natur (je nach Sensor einzusammeln mittels Lora) solltest Du irgendwann auch träumen davon lass es mich wissen. Mein Wissen ist jedenfalls zu gering bislang um den Traum umzusetzen. Du hättest ja dort einen Freund in Constanta vor Ort, der so etwas betreuen könnte. Vielleicht wird es ja einmal ein Projekt im grösseren Rahmen als Dein Sommerprojekt. Ein Mitmachprojekt für Deine Follower. Bislang kann ich Daten für die Wassertiefe sammeln. Aber die Idee oder der Traum Lora zu nutzen spinnt weiterhin. www.openseamap.org/index.php?id=bathymetrie&L=1
Ich selbst habe leider keine Zeit für Zusatzprojekte. TH-cam ist ja nur mein Hobby. Und mein letztes Sommerprojekt war nicht so erfolgreich. Aufwand zu Ertrag war schlecht für mich, auch wenn ich einberechne, was ich über die Passivität der Menschen gelernt habe :-(
Du kannst gerne Florin kontaktieren. Sein TH-cam Channel heisst Voltlog.
@@AndreasSpiess beim Sommerprojekt habe ich nur ab und an einmal quergelesen. Es hat einfach absehbar meinen FINANZRAHMEN um Welten gesprengt damals. Voltlog habe ich schon länger abonniert. Die Passivität von Internet Usern kann man anders durchbrechen.
@@AndreasSpiess Ich fange es mal so an. Du hast eine Biosphäre also Vögel, Fische und wenige Menschen und Du hast Lora und Bewegungssensoren. Das Fledermausprojekt um Lora war schon genial. Die Frage ist, kann man es übertragen? Was fällt Dir dazu ein on einem Brainstorming.
You should encourage people to take ham radio licence on first place. De VU3GDP.
I think you should watch my summary;-)
@@AndreasSpiess my concern is many students developing cube sat and nano sat using frequency reserved for ham radio, but without following the emission rating and other ITU convention rules, failing to make use of their satellite and get some critical data and feedback from a well established ham community across the world. These are termed as rouge sats in our community.
I personally feel, being a popular channel on TH-cam you can really help us in this regard.
Thanks in advance.
@@gurudattapanda FossaSat-1 complies with all IARU and ITU regulations.
@@FossaSystems thank you. Please publish your frequency of transmission, modes, telemetry for navigation and medium to submit the reports after the launch.
All the best.
Julian has a Spanish license. And most of the guys I see around the project are also licensed hams. So no worries.
My concern is more that our hobby disappears because no young people follow. Just check the average age at any Ham convention. And then, governments will take our frequencies away. Also not nice ;-)
Just for everyone’s info BIRDS 3 satellites already in orbit tx Over LoRa. Try to track them!!
How to track that? Here the description:
"The mission board has two RFM95W Semtec Long Range (LoRa) modulation based transceivers for LoRa Demonstration Mission (LDM). No antennas will be connected. The design has taken to ensure there are no RF leakage outside the satellite. A 50db attenuator has been placed between the two transceivers to ensure that."
Andreas Spiess please find info from this web site.
birds3.birds-project.com/2019/06/19/tle-data-of-birds-3-satellites/
You can find QSL info as well.
Thanks for your great videos. Waiting for the next one.
Thanks for giving the information. I'm a beginner but will add this as a project for sure. No idea what hardware etc. is needed yet, but let the journey begin :-)
@Tharanga: Where do I get the information on how to use the satellite?
@@AndreasSpiess with stamina :-) birds1.birds-project.com/amateur.html
"I hope not abs or pla" lol
Yes. Would probably melt ;-)
@@AndreasSpiess Andreas I am very curious about some experiments which are meaningfull only in space. There are some experiments and theores that claim violation of law of momentum conservation. Emdrive just one of such examples. Do you ever thought about checking some of them in space?
No, I do not understand a lot of mechanics :-(
Spanish technology
Made in China ;-)
nice, now when space debris fall on our heads we have a chance to dodge !
Pocket text message communicator anyone?
Maybe a slow response time if you have to wait for the next pass?
@@AndreasSpiess Agree, but more important that such a thing could now actually be realised at all - impossible before. Not sure if rubber duck whip antenna will have the required gain, but a slot or panel antenna has +10dB or more (slot dimensions 350x116 approx). Ideally it would be a cellphone-sized unit with at least a one-week battery life - an impressive pocket ham radio global toy that actually worked!
so, more micro junk in space that will trash the ground based optical/radio telescopes even more and be impossible to track after a failure.
This was also my first thought when I saw the video. Too small to observe the position and movement and too big for a mild crash with important orbit infrastructure.
@@clausdieterhamann1875 Such satellites do not have a very long lifetime because the mass/drag ratio becomes smaller and smaller when you have such a small formfactor.
(mass decreases by 3rd power, drag decreases by 2nd power)
Also the orbits are normally very low, in the 200km area.
So no need to be worried about space trash...
Amazing!!!!
Yes!
