摘要:

MICROSCOPE任务旨在以10^{-15}的精度检验弱等效原理(WEP)。弱等效原理指出,两个物体在引力场中以相同的速率下落,与其质量或成分无关。在MICROSCOPE任务中,两个不同成分的质量块(钛合金和铂合金)被置于绕地球的准圆轨道上,它们是双加速度计的检验质量。通过测量它们的加速度来提取可能存在的弱等效原理违反信号,该信号会出现在由卫星绕地球的运动和姿态所定义的频率上。本文详细阐述了任务的主要驱动因素,并由此给出主要分系统(卫星、地面段、仪器、轨道等)的规格要求。在测量方程的基础上,我们推导出检验目标在统计误差和系统误差分配中的要求,并给出任务的预期误差预算。

英文摘要:

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.
