WebIt shows that the Doppler effect is mainly related to the signal carrier frequency and the satellite orbit height. When the carrier frequency is larger, the satellite orbit height is lower, and the Doppler effect is more serious. For LoRa-LEO satellite communication system, the maximum carrier frequency is 928MHz, and http://www.infocobuild.com/education/audio-video-courses/electronics/SatelliteCommunicationSystems-IIT-Kharagpur/lecture-05.html
