Laboratory testing of LoRa modulation for CubeSat radio communications

Abstract

We report the results of the feasibility study of using LoRa modulation for radio communications between CubeSat at low Earth orbit and ground station. The main goal of the study is to define how Doppler effect affects a LoRa radio link. Results of laboratory testing have shown high immunity of LoRa radio link to Doppler shift and a possibility to use LoRa modulation in CubeSat radio communications without any limitations.
