| 摘 要： | 提出把空间数据系统的发展历程分为三个阶段：第一阶段是面向信道传输,主要解决数据如何在空间链路上有效可靠传输;第二阶段是面向数据源,主要解决如何自适应不同数据源的传输要求。这两个阶段的技术已经成熟并应用。文章预测,空间数据系统将走上第三阶段,即面向数据用户的体制,到那时用户可以根据自己的需求,主动从空间分布式数据库中获取数据。文章重点阐述了第三阶段的新概念设想,它的第一步是云遥测,然后进一步建成支持交互的空间云数据系统。

| Abstract: | Three phases of developing process for space data system are presented.The first is channel transmission-oriented,which mainly deals with effective and reliable data transmission in the space data link.The second is data source-oriented,which solves how to adapt different data source to different transmission requirements.The above-mentioned techniques have already been applied maturely.It is predicted that the space data system will come towards the third phase which is a user-oriented system.In this phase,the users can initiatively acquire the data from cloud database based on self-needs. In the paper,the new concept of the third phase is expatiated. The cloud telemetry is implemented firstly in this phase,and then the space cloud data system supporting interactivity is structured. |
