Abstract

The XMM-Newton X-ray observing astronomy mission, which is a prime component of ESA's scientific spacecraft programme for the new century, was launched by Ariane-504 from French Guiana on the 10th of December 1999. It was injected into a highly elliptical, 834 km/spl times/113990 km orbit, having an inclination with respect to the equator of 40/spl deg/. The spacecraft was built in Europe by an industrial team led by Dornier Space Systems (DSS) of Friedrichshafen, Germany with the onboard instruments provided by scientific institutions. The technical paper describes the XMM-Newton power system topology, its equipment characteristics and the early inflight operations. In addition two novel features related to the design of the electrical power system for XMM-Newton are reported in the technical paper, these being the implementation of a surface conductive network for the cover glasses of the solar cells and the extensive use of telecommandable and resettable latching current limiters (LCLs) for payload failure protection and ON/OFF switching.

x射线多镜(xmm -牛顿)动力系统[航天器动力]

xmm -牛顿x射线观测天文学任务是欧空局新世纪科学航天器计划的主要组成部分，于1999年12月10日由阿丽亚娜-504号从法属圭亚那发射。它被注入一个高度椭圆的轨道，834公里/spl次/113990公里，相对于赤道的倾角为40/spl度/。该航天器是由德国弗里德里希港的多尼尔空间系统公司(DSS)领导的一个工业团队在欧洲建造的，船上的仪器由科学机构提供。技术论文介绍了xmm -牛顿动力系统的拓扑结构、设备特点和早期飞行运行情况。此外，技术论文中还报告了与XMM-Newton电力系统设计相关的两个新特征，即太阳能电池盖板玻璃表面导电网络的实现，以及用于有效载荷故障保护和ON/OFF开关的可遥控和可复位闭锁限流器(lcl)的广泛使用。
