论文摘要
本文重点介绍了显微镜卫星的设计和性能及其无阻力和态度控制系统（DFACS）的描述。该卫星源自CNES的Myriade Platform家族，尽管它具有前所未有的显微镜任务要求的重大升级。 300千克的无拖力微卫星已经完成了2年的飞行，其性能高于预期。它的被动热概念允许在测量频率$ f _ {\ rm {ep}} $下大于1 $μ$ k的变化。推进系统提供了6轴连续的，并且非常低的噪声从零到数百个MicroNewtons。最后，其DFAC的性能（旨在补偿适用于卫星的令人不安的力和扭矩）是有史以来在低地球轨道中达到的最好的，沿三个轴的残留加速度低于$ 10^{ - 12} { - 12} {\ \ rm m/s}^2 $ f _ {
This paper focus on the description of the design and performance of the MICROSCOPE satellite and its Drag-Free and Attitude Control System (DFACS). The satellite is derived from CNES' Myriade platform family, albeit with significant upgrades dictated by the unprecedented MICROSCOPE's mission requirements. The 300kg drag-free microsatellite has completed its 2-year flight with higher-than-expected performances. Its passive thermal concept allowed for variations smaller than 1 $μ$K at the measurement frequency $f_{\rm{EP}}$. The propulsion system provided a 6 axis continuous and very low noise thrust from zero to some hundreds of micronewtons. Finally, the performance of its DFACS (aimed at compensating the disturbing forces and torques applied to the satellite) is the finest ever achieved in low Earth orbit, with residual accelerations along the three axes are lower than $10^{-12} {\rm m/s}^2$ at $f_{\rm{EP}}$ over 8 days.
