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?
Hi Ashhar,
LORA is/uses a proprietary protocol, however, it has already been reverse-engineered by software defined radio people, so ground stations could potentially use an SDR instead of a LORA chipset: https://myriadrf.org/blog/lora-modem-limesdr/

I think that it might be interesting to try EME with an FM-chirp signal (one optimised for the task ie not LORA) as an alternative to JT65...
