英文摘要	In recent years, the Internet of Things (IoT) technology has shown a good momentum of development and has been widely used in various fields of society. Satellite IoT, as an important complement and extension of the ground IoT, provides services in areas where oceanic and desert areas cannot build terrestrial IoT base stations. However, due to limited spectrum resources, spectrum sharing between terrestrial IoT and satellite IoT is likely to be required, which will inevitably lead to uplink and downlink co-channel interference between systems. This paper analyzes various interference scenarios that may occur on the uplink and downlink of terrestrial IoT and satellite IoT. Then, we establishes a global dynamic model of interference volume, and obtains the dynamic distribution of global interference of low-orbit satellite IoT through simulation. Finally, the paper uses the low-orbit satellite IoT global interference scenarios, interference distribution model and interference analysis model to obtain the dynamic analysis of the global uplink and downlink interference of the low-orbit satellite IoT, and uses the interference analysis results to give suggestions for the deployment of Low-orbit Satellite IoT.
