【摘要】 太空计算中心构建及运营技术是利用太空太阳能提供绿色能源，常态化提供“天数天算”“地数天算”等天地一体化算力服务的关键技术。针对地面数据中心存在高能耗、高碳排放及服务覆盖范围有限等问题，提出基于空间太阳能构建绿色低碳太空计算中心的方案。该方案通过太空建设和部署国家算力枢纽，实现“算电一体”的绿色能源优势与广域泛在接入服务优势的双重结合，既靠近绿色能源又靠近用户数据，形成“两优”选择。研究分析了太空计算中心的设计目标、构建与运营思路，提出“三步走”实施路径：关键技术试验、应用示范、中心构建与部署提升天基算力及通信服务能力。作为未来重要空间基础设施，太空计算中心具有绿色、经济、泛在、安全等特点，建成后将成为继通信、导航、遥感之后的第四类天基服务能力，有力支撑国家算力基础设施高质量发展。更多还原

【Abstract】 Technologies for space computing center construction and operation represent a key approach to providing green energy through solar power in space and routinely offering integrated space-ground computing services such as “space data processed in space” and “ground data processed in space”. To address the issues of high energy consumption, high carbon emissions, and limited service coverage in ground computing centers, a green and low-carbon space computing center based on space solar energy is proposed. This system achieves integrated computing services while establishing a national computing hub in space. The implementation promotes the realization and utilization of the “integrated computing and power” green energy advantages from space solar power stations and space computing centers. It also leverages the widespread and ubiquitous service access capabilities of space computing centers, combining proximity to green energy and user data. As a critical future space infrastructure, the space computing center is characterized by pollution-free, zero-emission, backup capabilities, and high security. Upon completion, it will become a new generation of space-based service capabilities following communications, navigation, and remote sensing, facilitating high-quality development of China’s arithmetic infrastructure.更多还原
