欧洲航天局的普朗克卫星于2009年5月14日发射升空，是宇宙微波背景研究领域的第三代空间实验。它将以前所未有的灵敏度(~2×10-6)和角分辨率(~5角分)拍摄CMB在整个天空的各向异性图像。普朗克将提供与许多基本宇宙学问题相关的主要信息来源，并将检验目前关于宇宙早期演化和结构起源的理论。它还将涉及与银河系以及外部星系和星系团有关的天体物理研究的广泛领域。普朗克能够在很宽的频率范围内(30-350 GHz)以高精度和精确度测量偏振，并覆盖整个天空，这将提供独特的见解，不仅是对特定的宇宙学问题，而且是对星际介质的性质。本文是描述普朗克科学有效载荷技术能力的系列文章的一部分。其依据是在主要分系统--主要是望远镜和两台科学仪器--的实地校准活动期间收集的知识，以及在完全集成的卫星一级进行的测试。它代表了发射前对卫星及其有效载荷将在飞行中实现的技术性能的最佳估计。在本文中，我们总结了有效载荷性能的主要元素，在随附的文件中详细描述了这一点。此外，我们还介绍了与科学最相关的卫星性能要素，并概述了科学操作和数据分析计划。
The European Space Agency's Planck satellite, launched on 14 May 2009, is the third-generation space experiment in the field of cosmic microwave background (CMB) research. It will image the anisotropies of the CMB over the whole sky, with unprecedented sensitivity ( ~ 2 × 10-6) and angular resolution (~5 arcmin). Planck will provide a major source of information relevant to many fundamental cosmological problems and will test current theories of the early evolution of the Universe and the origin of structure. It will also address a wide range of areas of astrophysical research related to the Milky Way as well as external galaxies and clusters of galaxies. The ability of Planck to measure polarization across a wide frequency range (30-350 GHz), with high precision and accuracy, and over the whole sky, will provide unique insight, not only into specific cosmological questions, but also into the properties of the interstellar medium. This paper is part of a series which describes the technical capabilities of the Planck scientific payload. It is based on the knowledge gathered during the on-ground calibration campaigns of the major subsystems, principally its telescope and its two scientific instruments, and of tests at fully integrated satellite level. It represents the best estimate before launch of the technical performance that the satellite and its payload will achieve in flight. In this paper, we summarise the main elements of the payload performance, which is described in detail in the accompanying papers. In addition, we describe the satellite performance elements which are most relevant for science, and provide an overview of the plans for scientific operations and data analysis.
