The invention belongs to the technical field of satellites, and particularly relates to a satellite attitude control flywheel pair, a satellite attitude control system comprising the satellite attitude control flywheel pair and a satellite comprising the satellite attitude control system. The satellite attitude controls the flywheel pair comprises a first flywheel body, a second flywheel body, a first driving device and a second driving device, wherein the first driving device is in transmission connection with the first flywheel body to drive the first flywheel body to rotate, the second driving device is in transmission connection with the second flywheel body to drive the second flywheel body to rotate, and the first flywheel body is arranged on the radial outer side of the second flywheel body. According to the satellite attitude control flywheel pair provided by the invention, the technical problems of large occupied space and disturbance caused by zero-crossing of the rotating speed of a flywheel pair in the prior art can be solved, the space occupied by the flywheel pair is reduced under the condition of ensuring the moment of inertia, and the satellite attitude control precision is improved.

    本发明属于卫星技术领域,特别涉及卫星姿态控制飞轮对、包括上述卫星姿态控制飞轮对的卫星姿态控制系统和包括卫星姿态控制系统的卫星。其中,卫星姿态控制飞轮对,包括第一飞轮体和第二飞轮体,以及,第一驱动装置和第二驱动装置,第一驱动装置与第一飞轮体传动连接,以驱动第一飞轮体自转,第二驱动装置与第二飞轮体传动连接,以驱动第二飞轮体自转,第一飞轮体设置在第二飞轮体的径向的外侧。本发明提供的卫星姿态控制飞轮对,可以解决现有技术中的飞轮对占用空间较大和转速过零带来扰动的技术问题,在保证转动惯量的情况下减少飞轮对所占用的空间,提高卫星姿态控制精度。
