A method and system for reconfiguring a spacecraft cluster

Abstract

The invention relates to a method and system for reconstructing a spacecraft cluster. First, by grouping a plurality of spacecraft in the spacecraft cluster, a group of spacecraft corresponds to a transition position, and then, according to the current position of each spacecraft and the corresponding The transition position of each spacecraft determines the corresponding termination position of each spacecraft, and finally controls each spacecraft to fly to the corresponding termination position of each spacecraft through the transition position corresponding to each spacecraft, so as to realize the formation reconstruction of the spacecraft cluster, The calculation amount is reduced, the efficiency is high, the problem that it takes a long time to determine the end position of the spacecraft in the global planning method is overcome, and the performance requirements for the host are reduced.

Description

technical field [0001] The invention relates to the technical field of spacecraft, in particular to a method and system for reconstructing a spacecraft cluster. Background technique [0002] At present, the cooperation of multiple spacecraft to complete some space missions has become a research hotspot in the space field. Some spacecraft clusters at home and abroad have been proposed one after another, such as the F6 plan, the EDSN small satellite, the CYNSS mission, the "Tiantuo-3" plan, MMS project, ESA's Cluster II program, etc. In the flight mode of the spacecraft cluster, formation reconfiguration is one of the key technologies. In order to adapt to different space missions, it is often necessary to change the formation of the spacecraft cluster according to the needs, that is, formation reconfiguration. The formation reconfiguration can be easily understood. To: carry out path planning for each spacecraft in the spacecraft cluster, which specifically refers to plannin...

AI Technical Summary

Problems solved by technology

[0003] However, when the number of spacecraft in the spacecraft cluster is large, when the existing global planning method is used to globally optimize the path of each spacecraft, there are problems such as large amount of calculation, long time consumption and high performance requirements on the host computer.
