PICARD有效载荷数据中心
The PICARD Payload Data Centre
摘要：
PICARD是一项科学空间飞行任务，致力于研究太阳变化的起源。一颗法国微型卫星将携带一个成像望远镜，用于测量太阳直径、边缘形状和太阳振荡，以及两个辐射计，用于测量太阳总辐照度和从紫外线到红外线的五个光谱域的辐照度。该飞行任务计划于2009年发射，为期3年。本文介绍了PICARD有效载荷数据中心，其作用是收集，处理和分发PICARD数据。有效载荷数据中心是实验室、空间机构和工业界之间的一个联合项目。比利时科学政策办公室为欧洲航天局计划下的工业发展和未来运营提供资金。该项目由SPACEBEL公司开发。比利时业务中心负责PICARD有效载荷数据中心的运营。法国航天局与负责提供所有科学算法的法国科学研究中心合作，领导开发工作。PICARD有效载荷数据中心的体系结构（软件和硬件）。该软件系统是基于面向服务的体系结构。主机结构由数据管理、任务调度和系统监控等基本功能组成，包括操作员用于与系统交互的图形界面。其他功能是针对具体任务的：数据交换（获取、分发）、数据处理（科学和非科学处理）和有效载荷管理（编程、监测）。PICARD有效载荷数据中心计划运行5年。所有数据将在此期间后存储到特定的数据中心。
英文摘要：
PICARD is a scientific space mission dedicated to the study of the solar variability origin. A French micro-satellite will carry an imaging telescope for measuring the solar diameter, limb shape and solar oscillations, and two radiometers for measuring the total solar irradiance and the irradiance in five spectral domains, from ultraviolet to infrared. The mission is planed to be launched in 2009 for a 3-year duration. This article presents the PICARD Payload Data Centre, which role is to collect, process and distribute the PICARD data. The Payload Data Centre is a joint project between laboratories, space agency and industries. The Belgian scientific policy office funds the industrial development and future operations under the European Space Agency program. The development is achieved by the SPACEBEL Company. The Belgian operation centre is in charge of operating the PICARD Payload Data Centre. The French space agency leads the development in partnership with the French scientific research centre, which is responsible for providing all the scientific algorithms. The architecture of the PICARD Payload Data Centre (software and hardware) is presented. The software system is based on a Service Oriented Architecture. The host structure is made up of the basic functions such as data management, task scheduling and system supervision including a graphical interface used by the operator to interact with the system. The other functions are mission-specific: data exchange (acquisition, distribution), data processing (scientific and non-scientific processing) and managing the payload (programming, monitoring). The PICARD Payload Data Centre is planned to be operated for 5 years. All the data will be stored into a specific data centre after this period.
