Before Christmas, I got a package from Lacuna. It contains this small module that should be capable of transmitting sensor data to a LoRa satellite and last for a few months with this battery. After my last experience with FossaSat-1, I am skeptical. Do you want to accompany me on the journey?
We all were disappointed when FossaSat-1 did not work. I would have loved to transfer a LoRa message from a 20 dollar sensor node via satellite to my computer before the turn of the decade. FossaSat-1 showed that many problems have to be solved before we can transfer a message via satellite. But let’s have a quick look at who sent me this package.

I love how it combines all Maker passions - the hardware side, software ingenuity, radio wireless comms using digital protocols, and especially outer space tech - its a Maker tour de force. Even something like a dedicated repeater has to address having a receiving antenna and transmitting antenna operating in close physical proximity - those industrial grade repeater installations up on mountain tops are really something - now condense that concept down into a tiny, affordable LoRa gadget - couple to a solar panel and appropriate battery, a weather proof enclosure - then spread them across the land on rooftops like a modern day Johnny Appleseed planting apple trees across a continent

I’ve made comms links over 9 miles through dense urban environments using LoRaChat and arduino. It was over the amateur bands, allowing me a watt of power, but if someone was capable of writing software to store and repeat, these devices could be dropped anywhere. No mains power is even required. Imagine a single solar panel and board on top of a high mountain or hill, acting as a repeater!? Even using non ham band frequencies, it’s totally possible to create 300+ mile coverage zones that allow users to send a short burst of data, and have it repeated out. It’s possible to create a bluetooth and app connection, so people could carry a small box, connect it to their smart phone, and send a text out, have it repeated, and received over a massive area. All without the internet, the cellular grid, etc… Ham radio is hard focused on voice comms and computer to computer data xfer. Someone needs to start looking at the modern world, where short texts and data xfer is king

@Andreas Spiess the lora capable hamshield goes far beyond meshtastic. The only drawbacks are that it requires a ham radio license and has no store and repeat functionality.

Likely sparking extreme interest in the field

Ich weiss nicht wie der Emfänger aufgebaut ist. Hier gibt es einen 868MHz Filter, wenn man einen braucht: www.aliexpress.com/item/32854454729.html

@@AndreasSpiess merci, ja den kenne ich. Und den gibt's auch noch www.passion-radio.com/ism/868-saw-830.html aber 3dB Verlust finde ich nicht so ermutigend. Aktuell nutze ich den sdr RTL v3 Stick, aber ich werde evtl zur Sicherheit auf einen günstigeren stick wechseln oder den Antennenabstand vergrößern, da ich doch Sorge habe, dass der Eingang vom sdr kaputt geht durch den sehr nahen airband Sender...

@ Andreas Spiess A great work sir. A big motivation for young Engineers to do research. I have a question can we achieve direct access to the geo satellites with this ? Is there any possibilities can you point out . Thankyou in advance . Have a great day God bless

@AndreasSpiess Жыл бұрын

No. You have to use other protocols. Maybe you watch my QO-100 video series

At the higher ISM (900 vs. 433) frequencies, doppler shift will be a bigger issue, especially at lower apparent elevations when the path length is changing more rapidly. I wonder if the space segment receivers have any special tweaks to deal with this? I'm not familiar enough with the LoRa waveform/modulation envelope to know if it would be particular sensitive or tolerant of doppler shift. Thanks again for the very interesting video!

@AndreasSpiess 4 жыл бұрын

LoRa seems to be well suited for doppler effect related problems because of its chirp technology. And I know from Thomas that they worked with Semtech on this problem.

Hello @Andreas, There is also a french company/project name Kineis (www.kineis.com/en/how-it-works/) which will be based on a constellation of 25 satellites. 1st prototyppe sat has been launhed on Dec 18th 2019. It is a follow-up on the ARGOS system which is well known world wide for tracking boats and which is also use low power beacons. They also offer Kineis Adventure for tracking adventurers similar to SPOT system or PLB (Personal Locator Beacon).

Unfortunately they don mot provide any technical data. So it is hard to assess.

@barbudor 4 жыл бұрын

@@AndreasSpiess I have asked for more details. Let's see what they will provide. There is also an article on the French Wikipedia (fr.m.wikipedia.org/wiki/Kineis) with little details on the satellites (cubes 20cm each side, 650km, UHF + VHF + S band antennas). Nothing clear on the exact frequencies used.

Andreas, great video and very exciting for you to receive a signal via sat! You mentioned fossasat you need an armature licence but for lacuna you do not. Is that because of the frequency used by both? Is 436 part of the HAM bandwidth but 866- is not? Greatly appreciate your videos

Yes. That is the reason

@AndreasSpiess 4 жыл бұрын

It still works. But not for the intended purpose because the antenna is not deployed. You need very big antennas and high power to reach it.

How will this topic aid a RC Plane that is using the .915 Frequency? I don't want to drop out of the sky with extra traffic?

@AndreasSpiess 8 ай бұрын

I do not see a problem there becuause your signal will be stronger and the chance you use the same channel is small.

Hi Andreas Thank you for your awesome video! Cool to see that it is possible to really get it running. Is it somehow possible to also test that service for a research project, do you know that? Beside that request, I also got in contact with Lacuna directly, but didn't get an answer yet :-). Gruess us de Schwiz!

congrats to this success and big Milestone. Ca. 30 years ago I visited ZDF in Mainz and learned that they had to pay ca. 20 times more for terrestrical distribution of their TV Programm than for distribution via satellite. So, if you are in the right economy in scale, satellite distribution will be beneficial. Btw.: Will the TV stations reduce the fee, when the distribution is migrated to cable which is payed by the consumer himself?

@AndreasSpiess 4 жыл бұрын

I think, TV stations need every penny because their economy of scale implodes right now. Recently I was featured on the local TV and got one reaction outside "family and friends". So I assume nearly nobody was watching :-(
