摘要
随着人类深空探测活动的不断深入以及计算机技术、新型存储技术的广泛应用,如何能够提高行星科学数据的长期可读性与可利用性,更为规范、有效地对行星科学数据进行存储、交换与服务,是空间科学领域开展深空探测活动的必然趋势和热点。行星科学数据系统(Planetary Data System,PDS)是由美国国家航空航天局(NASA)在此需求背景下提出并在国际深空探测领域广泛推广的一种数据存储标准。本文着重介绍了PDS的基本概念、组织标准和核心思想,并分析了PDS数据存储的优势,就我国PDS标准的应用前景进行了初步探讨。
Nowadays,deep-space probing activities have become more and more frequent,it is inevitable for space scientists to make good use of new computing and storage technologies to continuously improve the readability and the long-term availability of planetary science data and to carry out data storage,exchange and services more standardized and effectively.Under this circumstance,the National Aeronautics and Space Administration(NASA) of the United States proposed and promoted the Planetary Data System(PDS) as an international standard for the whole deep-space survey community.This article introduces the basic concept,the organization and the main idea of the PDS,analyzes the advantages of the PDS data storage and discusses the application prospects of the PDS standard in China.
