Embodiment Construction
[0023] In order to solve the following problems in the prior art: In the existing distributed constellations with no center topology, the functions of each satellite are relatively single and complex, and various forms of data processing cannot be performed, and the system performance is poor; this paper The invention provides a distributed constellation system and an information system. The invention will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0024] The first embodiment of the present invention provides a distributed constellation system, the architecture of the distributed constellation system figure 1 shown, including:
[0025] M exchange satellites 1 and N task satellites 2; wherein, an inter-satellite analog link ( figure 1 Indicated by the solid line) and the inter-satel...

The invention discloses a distributed constellation system and an information system. The distributed constellation system includes: M exchange satellites and N mission satellites; Analog links and inter-satellite digital links, inter-satellite analog links are set between each mission satellite and other N-1 mission satellites, and inter-satellite analog links are respectively set between each switching satellite and other M-1 switching satellites Inter-satellite analog link and inter-satellite digital link; both M and N are integers greater than or equal to 2. In the present invention, an inter-satellite analog link and an inter-satellite digital link are arranged between the exchange satellite and the mission satellite, and different exchange loads are set, so that the analog exchange and the digital exchange can be performed simultaneously in the distributed constellation without a center topology structure, The function is diversified, the system performance is improved, and the problems of the prior art are 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.). ...
