Modeling and Simulation Implementation of a Large-Scale Multi-Scenario Space Remote Sensing Satellite System
Online published: 2026-02-11
在全球商业航天浪潮推动下,遥感星座应用正加速向超大规模部署与多场景市场化转型。传统仿真工具面临模型耦合度高、扩展性不足、场景适配单一及缺乏商业效能量化能力等突出问题,难以支撑星座设计论证与运营决策。聚焦大规模多场景航天遥感卫星仿真系统构建方法,设计并实现了一套一体化、高保真、可扩展的仿真系统,该系统采用“应用层-任务层-服务层-基础支撑层”四层架构,突破超大规模星座仿真瓶颈;采用组件化与参数化融合的建模方法,实现卫星平台、光学/合成孔径雷达载荷等核心组件的灵活复用与快速配置;构建基于标准化配置文件的多场景驱动机制,支持商业测绘、农业监测等多元化场景的一键切换。该系统基于“任务驱动-资源协同-数据闭环”核心逻辑,贯通从任务解析、资源调度到数据产出的全链路,可量化任务完成率、资源利用率等商业效能指标。仿真结果表明,该系统可有效支持50~10 000星量级星座的仿真验证;与传统装备体系建模周期(通常为1~2个月)相比,该系统的装备体系建模效率能够缩短至1~2天,显著降低商业星座研制风险与运营成本,提升市场化响应速度,为我国超大规模商业遥感星座的数字化建设、任务规划优化与效能评估提供了关键技术支撑。

Driven by the global commercial space wave, remote sensing constellations are accelerating their transformation towards ultra-large-scale deployment and multi-scenario market-oriented applications. Traditional simulation tools face prominent problems such as high model coupling, poor scalability, single scenario adaptability, and lack of commercial effectiveness quantification capabilities, making it difficult to support constellation design demonstration and operational decision-making. To address these issues, this paper focuses on the construction method of a large-scale multi-scenario space remote sensing satellite simulation system, and proposes and implements an integrated, high-fidelity, and scalable simulation platform. A four-layer architecture of “Application Layer - Task Layer - Service Layer - Basic Support Layer" is innovatively designed to break through the bottleneck of ultra-large-scale constellation simulation. An integrated modeling method combining component-based and parameterized approaches is adopted to realize flexible reuse and rapid configuration of core components such as satellite platforms and optical/synthetic aperture radar payloads. A multi-scenario driving mechanism based on standardized configuration files is constructed to support one-click switching of diversified scenarios including commercial mapping and agricultural monitoring. Based on the core logic of "mission-driven-resource collaboration - data closed-loop”, the complete link from mission analysis, resource scheduling to data output is connected, and commercial effectiveness indicators such as task completion rate and resource utilization rate are quantified. Simulation results show that the system can effectively support the simulation verification of constellations with a scale of 50~10 000 satellites, compared with the modeling cycle of traditional equipment systems (usually 1~2 months), the modeling cycle of the system can be shortened to within 1~2 days, significantly reduce the development risk and operational cost of commercial constellations, and improve the market response speed. The research in this paper provides key technical support for the digital construction, mission planning optimization and effectiveness evaluation of China’s ultra-large-scale commercial remote sensing constellations.
