Ordinary Satellite Ground Stations cost millions. We will build one for 20 dollars for the newly launched LoRa satellite. Let’s build it in parallel to the launch of the Electron spacecraft from Rocket Lab. Will it be successful? In my last video, I announced that the 16-year old Julian Fernandez and a small team built FossaSat-1. We will accompany the launch and in parallel, we will build a Ground Station and test it with the real satellite. Will it work?

For the moment, the TTGO boards seem not be supported by the satellite. Better use an ESP32 and this board: s.click.aliexpress.com/e/kRL6uyYY

The satellite currently is not working properly and cannot be reached with small antennas. Also the TTGO board shown in this video currently seems not be supported. Look at the alternative in the description or follow the Telegram stream.

[@FossaSystems]

An update for everyone here: FOSSASAT-1 is shown to be working correctly and healthy. However, due to the antennas not having deployed, the signal is very weak and can only be picked up with large antennas. LoRa remains not functional for small stations due to this. We are working to deploy the antennas manually from earth and hope to fix the issue. We are also launching two more LORA satellites in march to expand the network :)

This is brilliant. Thanks, Andreas, for covering it otherwise I'd have been completely unaware!

[@myounges]

Thank you Andreas for your efforts to teach and share all this information!

[@stationHQ]

Just what we have been waiting for since the word Lora became known! As usual Andreas, thanks for your pioneering work and putting us in the forefront of following and joining in the creation of ground base stations! Keep up the good work

[@garthmikles3933]

Thanks again Andreas for the concise information and instruction. Your work is greatly appreciated and your teaching and sharing with us is profound.

[@anandmoon5701]

Good initiative by young scientist, and many thanks to you Andreas for explaining the logic behind the operation. you have made this complex concept much simple to understand.

[@sarveshk09]

Amazing Job 👌 FOSSA Team! And as always thanks for a great video Uncle Andreas!

[@lintangwisesa]

Great story & super clear explaination, Sir. Thanks a lot.

[@GeorgeWMays]

So cool. An old friend of mine used to say "neatness is its own reward." This stuff is neat.

[@delta-game]

Awesome! Please keep us up to date on this one.

[@HolgerBarske]

Amazing adventure. I hope this going to deliver results soon 👍.

[@avejst]

Impressive work the young people have done

[@joeynovak07]

Wow!!! Sooo cooool!! Thanks for posting this.

[@metalpachuramon]

Wow! That's awesome, I didn't know that there were these kind of satellites for people to experiment with

[@ZechyC]

Brilliant video. Thanks Andreas

[@StephenFarthing]

Another great episode from the ham with the Swiss accent. :-)

[@brainfornothing]

Very interesting. Thanks for sharing !

[@chris.b83]

damn, how cool ist that "finger stick" :D

Andreas - when working amateur satellites on the 70cm band with a simple whip antenna from a handheld, i use a whip that’s around double the size of the one shown. Also i have to hold it at an angle and i have to change angle as the satellite passes. If 0 degrees means holding it perfectly vertical and 90 degrees means horizontal, then for best reception i need to hold it at around 15 degrees to acquire the sat as it comes above the horizon then over the next 6 minutes or so i have to follow its trajectory over the sky, keeping the whip antenna pointing perpendicularly at the sat. You probably know all this already but i mention it because a purely vertical orientation is really hard to make work at higher powers so lora powers i expect even more trouble (although lora’s far better sensitivity should help offset this but not sure by how much)
