We study the effects of rotations on a cold atom accelerometer onboard a Nadir pointing satellite. A simulation of the satellite attitude combined with a calculation of the phase of the cold atom interferometer allow us to evaluate the noise and bias induced by rotations. In particular, we evaluate the effects associated to the active compensation of the rotation due to Nadir pointing. This study was realized in the context of the preliminary study phase of the CARIOQA Quantum Pathfinder Mission.
我们研究了旋转对指向天底的卫星上的冷原子加速度计的影响。结合卫星姿态模拟和冷原子干涉仪相位计算，我们能够评估旋转引起的噪声和偏差。特别是，我们评估了与天底指向导致的旋转主动补偿相关的影响。这项研究是在CARIOQA量子探路者任务的初步研究阶段进行的。
