星载数据系统通过全星的计算机联网，建立统一数据管理，支持系统重组。文章探讨了星载数据系统结构的选择原则；并提出并行计算机系统的几种结构（如网格形和交叉开关网络）比目前使用的总线型结构更适合星载数据系统。
The satellite data system through the all-star computer networking, the establishment of unified data management, support for system reorganization. This paper discusses the principle of selection of the system structure of spaceborne data. Several structures of parallel computer system (such as grid and crossbar network) are proposed to be more suitable for the spaceborne data system than the current bus structure.
