Distributed satellite cluster system and information system

Abstract

The invention discloses a distributed satellite cluster system and an information system. The distributed satellite cluster system comprises M switching satellites and N task satellites; an inter-satellite analog link and an inter-satellite digital link are arranged between each task satellite and each switching satellite; the inter-satellite analog link is arranged between each task satellite andeach of other N-1 task satellites, and the inter-satellite analog link and the inter-satellite digital link are arranged between each switching satellite and each of other M-1 switching satellites; each of M and N is an integer greater than or equal to 2. The inter-satellite analog link and the inter-satellite digital link are arranged between the switching satellite and the task satellite, and different switching loads are provided so that the analog switching and the digital switching can be simultaneously performed in the distributed satellite cluster without a center topology structure, the function is diversified, the system performance is improved, and the problem of the prior art is solved.

Description

technical field [0001] The invention relates to the communication field, in particular to a distributed constellation system and an information system. Background technique [0002] Due to its unique space advantages, the space information network has an irreplaceable position in ground observation, emergency communication, aerospace measurement and control, air transportation, etc., and has gradually become a strategic high ground for competition among countries. Relevant institutions and organizations around the world have invested a lot of manpower and material resources in research and experimental verification of spatial information network related technologies. [0003] Due to the limitations of platform capabilities and long construction and deployment cycles, traditional single satellites are difficult to meet the various application requirements of space information network for network nodes (such as broadband access, relay transmission, on-orbit processing, etc.). ...
