Satellite Cloud Architecture Based on Resource Virtualization Technology

Nowadays, in-orbit spacecraft functions and system is relatively isolated, leading to low utilization rate of space resources. Different types of satellites coordinate poorly with each other; Task planning utilizes artificial planning and manual uploading methods, leading to low flexibility and timeliness. In response to these conditions, this paper proposes a satellite cloud architecture basing on resource virtualization technology. The architecture forms a shared resource pool with non-standardized aircraft heterogeneous resources by using virtualization technology, and user could call the standardization resources to achieve various types of space missions. The architecture can effectively coordinate multi-type spacecraft resources, including information acquisition, information processing, storage, transmission and other kind of resources, to provide wide-area high-precision remote sensing, massive data processing, highly reliable storage and efficient distribution/transmission functions, which single satellite can't achieve. The architecture can change the current task planning process to improve the flexibility and timeliness, to improve the utilization of space resources, enhancing the overall application performance of spacecraft.
