Abstract随着小卫星技术以及卫星组网技术的飞速发展,天基资源的规模呈爆发式增长,依赖多种类卫星节点提供的卫星能力,完成多星协同的复杂空间任务,向普通大众用户提供可用的、即时的卫星信息服务,成为未来发展的趋势。针对多类异构卫星,提出一种面向用户的应用层天基资源能力虚拟化方法。分析了即时观测信息服务的用户需求及天基资源的属性特征,综合时间、空间、能源、存储等约束条件,将天基资源按照时空逻辑,分层抽象虚拟化成面向用户的服务能力,建立了适用于大规模异构卫星、统一标准的应用层天基资源虚拟化方法,并设计了计算模型。选取具有代表性的卫星平台、载荷等,针对在轨实时虚拟化的需求,设计并实现了在轨虚拟化算法。试验证明,算法时效性可以满足星上实时计算要求。
Other AbstractWith the rapid development of small satellite technology and satellite networking technology,the scale of space-based resources is exploding. Relying on the satellite capabilities provided by various types of satellite nodes, it has become a future development trend to complete multi-satellite coordinated complex space tasks and provide the general public with available and real-time satellite information services. Therefore,in this paper,a user-oriented application layer space-based resource capability virtualization method is proposed for multiple heterogeneous satellites. The user requirements of real-time observation information services and the attribute characteristics of space-based resources are analyzed. The constraint conditions such as time,space,energy,and storage are integrated. The spacebased resources are hierarchically and abstractly virtualized into user-oriented service capabilities according to the spacetime logic. A method suitable for large-scale heterogeneous satellites and application layer-based resource virtualization with unified standards is established,and the computational model is designed. Representative satellite platforms, loads,etc. are selected to design and implement the in-orbit virtualization algorithm according to the in-orbit real-time virtualization requirements. The experimental results show that the timeliness of the algorithm can meet the real-time calculation requirements on the satellites.
