[amsat-bb] Lora and other modes

2 Jul 2017


      Is Lora a candidate for satellites? How well does it handle doppler? Given
that it uses CSS(Chirp Spread Spectrum), it is claimed to be resilient to
doppler shift.
Does anybody have any further details or knowledge? My understanding is
that the RFM22B didn't use LORA protocol as used in the $50 sat.
I'd appreciate more details. We are trying to evaluate a radio technology
that is widely and cheaply available to be placed into a cubesat.
