论文摘要
显微镜任务旨在测试弱等价原理（WEP）的精度为$ 10^{-15} $。 WEP指出，两个物体以相同的速率在引力场上降低，而与其质量或组成无关。在显微镜中，将两个不同组合物（钛和铂合金）的质量放在地球周围的准圆形轨迹上。它们是双加速度计的测试量。其加速度的测量用于提取侵犯潜在的WEP违规行为，该违规行为将以卫星在地球周围的运动和态度定义的频率发生。本文详细介绍了任务的主要驱动力，导致主要子系统（卫星，地面部门，仪器，轨道...）的规格。在测量方程式的基础上，我们以统计和系统的错误分配得出了测试的目标，并提供了任务的预期错误预算。
The MICROSCOPE mission aimed to test the Weak Equivalence Principle (WEP) to a precision of $10^{-15}$. The WEP states that two bodies fall at the same rate on a gravitational field independently of their mass or composition. In MICROSCOPE, two masses of different compositions (titanium and platinum alloys) are placed on a quasi-circular trajectory around the Earth. They are the test-masses of a double accelerometer. The measurement of their accelerations is used to extract a potential WEP violation that would occur at a frequency defined by the motion and attitude of the satellite around the Earth. This paper details the major drivers of the mission leading to the specification of the major subsystems (satellite, ground segment, instrument, orbit...). Building upon the measurement equation, we derive the objective of the test in statistical and systematic error allocation and provide the mission's expected error budget.
