Space-based resource on-orbit virtualization method based on available capacity calculation

Abstract

The invention discloses a space-based resource on-orbit virtualization method based on available capacity calculation, which is used for calculating the available capacity of space-based resources ofa single-satellite or multi-satellite cooperative task, and comprises the following steps: dividing the available capacity of a current satellite into three types: information observation capacity, information processing capacity and information transmission capacity; calculating an available observation space-time strip list of all observation loads; calculating an available data processing duration list of all processing loads; and calculating a transmission capability available time period list of all inter-satellite transmission and satellite-ground distribution devices. According to the method, various observation loads, calculation loads and communication equipment can be virtualized into three space-based resource capacities in a unified mode, a standardized space-based resource available capacity list description method is provided, and the unified management and collaborative application requirements of various heterogeneous satellites are met. In addition, due to the fact that space-based resource abstract analysis and description oriented to the user service capability level are used, open use of space-based resources to the general public can be supported.

Description

technical field [0001] The invention relates to the aerospace field, in particular to an on-orbit virtualization method of space-based resources based on available capacity calculation. Background technique [0002] In recent years, micro-satellite technology and satellite networking technology have developed rapidly, and the scale of space-based resources has grown explosively. Satellite applications have gradually developed from single-satellite applications to multi-satellite collaborative applications such as multi-satellite networking and satellite clusters; at the same time, the next A generation of satellite applications is accelerating integration with the Internet industry, introducing protocols, routing and other terrestrial Internet technologies into space-based networks, using space-based resources to develop Internet + satellite services, and forming a global "space-based Internet" that provides instant services according to user needs , is the future direction ...

AI Technical Summary

Problems solved by technology

[0006] In the above-mentioned studies and projects, most of the services focus on the completion of communication and networking with global coverage, and the technology focuses on the ground cloud system rather than the satellite in-orbit implementation, which can support the opening of space-based resources for general public users and support application-oriented on-orbit virtualization technology for orbital space-based resource management and organization remains unreported
