| Abstract_FL | The architecture of satellite Internet composed of LEO satellites with remote sensing/inter-satellite and satellite-earth net-working,on-board edge computing functions,and ground cloud computing centers,and various types of terminals such as sky,near space,space,ground,sea terminals was put forward.The functional architecture of on-board edge computing,included resource layer,virtualization layer,service layer,service management layer and application layer was given.On the basis of proposed the construction method of on-board edge computing simulation and verification system,a satellite Internet simulation and verification system serving space sensing services was designed,and space-based sensing information processing and distribution experiments were carried out.According to the comparison of network resource occupation and user service delay with different information processing and distribu-tion methods,the capability level of satellite Internet for space sensing services under different capability conditions were analyzed. |
