What max slant range? LoRa has architecture constraints... it's purposely time constrained for link quality. Longest so far is terrestrial about 766km I believe

But at altitude, your smallsat slant range to ground station will be an issue, should it not?

Subject: [AMSAT-BB] Any lora sats active?

I planning a mission that could use lora modulation for telemetry/command. Does anyone know the status of fossasat and lorasat, etc?

Also, what is Amsat/IARU stand on use of Lora (a proprietory protocol) on ham bands? I wish we had a standard weak signal protocol for amatuer sats that is doppler insensitive.
