Architecture design and optimization system of earth observation satellite

Abstract

An architecture design and optimization system of an earth observation satellite is composed of an artificial subsystem of an earth observation satellite system, a capability evaluation subsystem of the earth observation satellite system, a comprehensive demonstration subsystem and subsystem for designing and configuring operation control strategy of earth observation satellite system. The artificial subsystem of the earth observation satellite system is the core of the earth observation satellite system structure design and optimization system. After loading of the information of the operation control strategy and the system structure, the computational experiment research is carried out, the quantitative index of the system efficiency is obtained through the system capability evaluationsubsystem, and support is provided to produce the next step optimization suggestion;. Visual display and analysis of system state variables are realized by the integrated demonstration subsystem, which supports the demonstration and evaluation of system capability. The system can be used to support the planning and evaluation of the earth observation satellite system cooperative work scheme, the analysis and evaluation of the system routine operation scheme and emergency task scheduling scheme, and the evaluation and optimization of the system configuration scheme and construction developmentscheme.

Description

technical field [0001] The invention belongs to the technical field of earth observation satellites, in particular to an earth observation satellite system structure design and optimization system. Background technique [0002] With the rapid development of aerospace technology, the earth observation satellite has gradually developed from the early single-star model to the constellation model, and the resolution of the satellite is getting higher and higher, basically realizing the all-time, all-weather, and all-round coverage of the earth observation. With the rapid increase in the number of earth observation satellites, there are more and more types of optical remote sensing satellites and SAR remote sensing satellites, and their functions are becoming more and more complex. How to realize the optimal design of the earth observation satellite architecture while the number of satellites is increasing, It is an urgent problem to be solved, and the main needs are reflected in...
