Distributed reconfigurable satellite system organization method based on mosaic splicing

Abstract

The invention discloses a distributed reconfigurable satellite system organization method based on mosaic splicing. The method comprises the following steps: establishing a structural model of a satellite agent; after receiving a task sent by the ground, enabling the satellite agent to quickly establish connection with a nearby satellite agent; splitting the mosaic capability according to the effective load capability of the satellite to obtain mosaic capability modules; performing mosaic splicing on the split mosaic capability modules, and establishing a space mosaic reconfigurable system two-stage system hybrid control structure model with a management satellite agent and a working satellite agent; enabling a management satellite agent to determine a task planning and scheduling scheme of the multi-satellite cooperation, wherein the working satellite agent judges whether an issued task conflicts with an original task of the working satellite agent or not, if yes, the management satellite agent newly formulates a scheme, and the task is executed until the conflict disappears. According to the method, task execution is expanded to multiple dimensions, the task execution effect is comprehensively improved, and the target recognition probability is improved.

Description

technical field [0001] The invention relates to a method for organizing a distributed reconfigurable satellite system based on mosaic mosaic, and belongs to the field of aerospace. Background technique [0002] Distributed Satellite System (Distributed Satellite System, DSS) is a task architecture composed of multiple satellites, through which the satellites in the system cooperate with each other to complete tasks such as earth observation, navigation, and communication. [0003] The existing distributed satellite system is formed by a designated satellite network, which can be used by distributed satellites for internal collaboration, independent decision-making, planning and scheduling, and autonomous execution of tasks. Distributed satellite system can be divided into constellation, satellite formation, satellite cluster, satellite train, separate module satellite system, federal satellite system system etc. [0004] Different types of distributed satellite systems hav...

AI Technical Summary

Problems solved by technology

[0006] The inventor found that the existing distributed satellite system focuses on the on-orbit coordination of single satellites, and the flexibility of inter-satellite networking is poor. It must be composed of satellites pre-designated by ground personnel, and satellites in orbit cannot be easily added

After networking, the capability mode of the distributed satellite system is single, and the capability mode cannot be flexibly changed according to the mission characteristics

Such as GPS constellation can only be used for navigation
