摘要:

测试弱等效原理(WEP)的精度为$10^{-15}$需要大量的数据,这些数据对最终结果有足够的信心:理想情况下,测量时间越长,对统计噪声的抑制越好。科学会议最多持续120个轨道,定期重复并间隔开,以适应操作限制,但也是为了在不同条件下重复实验,并留出时间校准仪器。在2.5年的实验期间进行了几次科学会议。本文的目的是描述如何产生的数据的基础上的任务情景和数据流过程中,由科学目标和业务约束之间的权衡。这次飞行任务由法国国家空间研究中心领导,该中心提供卫星、发射和地面操作。地面部分由法国空研中心和国家航空航天研究和探索局负责。法国国家空间研究中心通过Centre d'Expertise de Compensation de Traumnée(CECT:无阻力专门知识中心)提供原始数据。这项科学研究由蔚蓝海岸天文台牵头,法国国家天文台研究所负责数据处理。后者还提供了仪器和显微镜科学任务中心。

英文摘要:

Testing the Weak Equivalence Principle (WEP) to a precision of $10^{-15}$ requires a quantity of data that give enough confidence on the final result: ideally, the longer the measurement the better the rejection of thestatistical noise. The science sessions had a duration of 120 orbits maximum and were regularly repeated and spaced out to accommodate operational constraints but also in order to repeat the experiment in different conditions and to allow time to calibrate the instrument. Several science sessions were performed over the 2.5 year duration of the experiment. This paper aims to describe how the data have been produced on the basis of a mission scenario and a data flow process, driven by a tradeoff between the science objectives and the operational constraints. The mission was led by the Centre National d'Etudes Spatiales (CNES) which provided the satellite, the launch and the ground operations. The ground segment was distributed between CNES and Office National d'Etudes et de Recherches Aérospatiales (ONERA). CNES provided the raw data through the Centre d'Expertise de Compensation de Traînée (CECT: Drag-free expertise centre). The science was led by the Observatoire de la Côte d{'}Azur (OCA) and ONERA was in charge of the data process. The latter also provided the instrument and the Science Mission Centre of MICROSCOPE (CMSM).
