The evaluation of microvibrations effect is crucial for the success of remote sensing missions. The moving parts on the satellite such as reaction wheels can create microvibrations disturbances, which cause degradation of image quality. In our paper we present an experimental investigation methodology for on-ground quantification of wheel noise disturbance transmitted through the structure to the payload. This assessment was carried out for the ALSAT-1B satellite integrating a medium resolution payload. The angular motion along imager bore sight was measured using accelerometers and verified against image quality and mission requirement. The on ground experimental methodology suggests that the effect of microvibrations on a camera can be verified directly.

微振动效应的评估对于遥感任务的成功至关重要。卫星上的运动部件如反作用轮会产生微振动干扰，从而导致图像质量下降。在我们的论文中，我们提出了一种实验研究方法，用于对通过结构传输到有效载荷的车轮噪声干扰进行地面量化。该评估是针对集成了中等分辨率有效载荷的ALSAT-1B卫星进行的。使用加速度计测量沿成像仪瞄准线的角运动，并根据图像质量和任务要求进行验证。地面实验方法表明可以直接验证微振动对相机的影响。
