摘要/Abstract

摘要：

借鉴基于模型的系统工程方法(model based system engineering，MBSE)模型化设计思想，构建了一种适用于低轨通信卫星设计分析的模型架构，该架构采用多维矩阵式思路：在纵向维度上，贯穿任务层、系统层、卫星总体层及分系统层，实现自顶向下的层级解耦；在横向维度上，构建了涵盖需求域、功能域、结构域与性能域的全视图映射机制。融合产品研制特点，建立了一套覆盖任务论证、总体设计、分系统设计及集成验证全生命周期的建模流程。结果表明：该方法在低轨通信卫星设计阶段能够有效完成需求分析和总体设计，提升整体设计质量，同时对低轨通信卫星研制转型具有重要参考意义。

关键词: 低轨通信卫星, MBSE(model based system engineering), 模型架构, 需求分析, 总体设计

Abstract:

Drawing on the model-centric design philosophy of model-based systems engineering (MBSE), this study constructs a model architecture suitable for the design and analysis of low Earth orbit communication satellites. This architecture adopts a multi-dimensional matrix approach. Vertically, it traverses the mission layer, system layer, satellite general design layer, and subsystem layer, achieving top-down hierarchical decoupling. Horizontally, it establishes a comprehensive view mapping mechanism covering the domains of requirements, functions, structure, and performance. Integrating the characteristics of product development, a modeling process covering the entire lifecycle—from mission demonstration and overall design to subsystem design and integration verification—has been established. The results indicate that this method can effectively accomplish requirement analysis and overall design in the design phase of low Earth orbit communication satellites, thereby enhancing overall design quality. It also holds significant reference value for advancing the development paradigm of low Earth orbit communication satellites.

Key words: low Earth orbit communication satellite, model-based system engineering (MBSE), model architecture, requirement analysis, overall design
