NG-14/ELaNa 31 Launch and Deployment Information

Unfortunately there will likely never be a LoRa flow-graph in SatNOGS due to the patent-encumbered nature of the LoRa physical layer.
The gr-lora project (which seems mostly abandoned?) does exist, but is reverse engineered, doesn’t perform well, doesn’t work with all parts of the LoRa protocol, and still has the patent issues surrounding it.

This means that while SatNOGS has a huge network of receiving stations around the world, none of them will be able to automatically receive telemetry from satellites transmitting LoRa. This is what you get for using a proprietary modulation technique unfortunately.

I should also point out that LoRa’s chirp spread-spectrum modulation is designed for use on the ISM bands, where there are usually many competing stations resulting in interference, which the spread-spectrum part of the modulation helps deal with. LoRa is well suited for those bands.

However, on the amateur satellite band, with frequency coordination and much less interference issues, all that spread-spectrum modulation does is use up far more bandwidth than is necessary (250 kHz on Norbi, really?!?!), resulting in potential interference to other satellites.

At some point there needs to be a discussion with the IARU about the use of proprietary PHY on the amateur radio bands…
