5G At the beginning of business , The world has quietly started 6G Fierce competition in research and development , Especially in America , Hope to pass 6G R & D reshapes its dominant position in the communications industry .6G The network will realize the integration of heaven and earth , The musk Starlink Constellation construction is currently 6G The first substantive attempt [1]. In China 2019 year 11 Officially launched in 6G Technology research and development , And in 2021 year 3 Month proposed “ Forward looking layout 6G Network technology reserve ”[2].

6G stay 5G Further integrate satellite communication on the basis of Technology 、 Artificial intelligence （AI, Artificial Intelligence） And big data technology [3], Break through the limitations of terrain and surface , Expand into space 、 In the air 、 land 、 Natural space such as the ocean , Truly realize global “ Ubiquitous connection ”[4]. however , At present, satellite communication is mainly transparent forwarding , The network architecture is simple , The space-based computing ability of satellite payload is weak , Information processing mainly depends on the ground data center , Unable to meet 6G Star land in the scene 、 Inter satellite interconnection 、 The demand for extremely low communication delay and efficient computing power .

For this reason , This article is about the future 6G The star earth coordination of the times AI、 The efficient space-based computing of cloud side collaboration and the integrated heterogeneous space-based computing technology suitable for multiple services are discussed and prospected .

Since the last century 60 Since the s, satellite communication technology and its applications have developed vigorously , It has been synchronized by a single earth
