摘要

引力波探测是当代物理学最重要的前沿领域之一，与引力波的地面探测相比，引力波的空间探测能够探测更丰富的波源和更遥远的目标，具有重大的科学价值。空间引力波探测带来了空前的技术挑战，对航天器系统和平台提出了极高的技术指标要求，传统的卫星平台难以满足任务需求，必须设计开发新的平台，并突破诸多关键技术。本文对空间引力波探测航天器总体和平台设计面临的挑战、主要的设计约束条件进行了分析，提出了天琴引力波探测航天器的总体方案设想和初步的构型布局方案，对航天器平台所涉及的关键技术进行了梳理，并对后续解决途径提出了建议。

Abstract

The detection of gravitational wave is a leading edge scientific research area in contemporary physics. Compared to the detection on the ground， the space based gravitational wave detection can explore richer gravitational wave sources and more distant objects， and so is considered to be of great scientific value. The detection of gravitational wave in space brings great technical challenges and presents demanding technical requirements for the spacecraft system and platform. Traditional platforms can not meet the mission requirements. The ultra-quiet and ultra-stable platform has to be developed. A series of critical technologies need to be broken through. This paper analyzes the technical challenges and constraints faced by the spacecraft system and platform for gravitational wave detection. The preliminary spacecraft system design concept for TianQin gravitational wave detection mission， including spacecraft configuration and layout， is proposed. The critical technologies for spacecraft platform are also analyzed and solution approaches are suggested.
