The motion of aerodynamically stabilized nanosatellites of the CubeSat design is studied. The features of the nanosatellites behavior in low orbits are conditioned both by the atmospheric effects and their own mass and inertial characteristics: the lifetime of nanosatellites is shorter, while the angular acceleration generated by the aerodynamic moment is much higher as compared with big satellites having large mass. CubeSats may experience resonance modes of motion caused by the shape factor of a rectangular parallelepiped. In addition, the existing commercial CubeSat deployers often generate large initial angular velocities that are random in nature. The conditions that cause the specific features of the CubeSat motion are considered and analyzed. A probabilistic approach to choosing their mass and inertial characteristics is proposed. The problems of motion stabilization are studied, and recommendations are formulated on the design of aerodynamically stabilized CubeSats with a passive/active magnetic damping system.

CubeSat设计的气动稳定纳米卫星的运动分析和综合

研究了CubeSat设计的空气动力学稳定的纳米卫星的运动。纳米卫星在低轨道上的行为特征受大气效应及其自身质量和惯性特性的制约：纳米卫星的寿命较短，而与较大的大型卫星相比，由空气动力学力矩产生的角加速度要高得多质量 立方体卫星可能会遇到由长方体的形状因子引起的共振运动模式。此外，现有的商用CubeSat部署者通常会产生本质上随机的大初始角速度。考虑并分析了导致CubeSat运动的特定特征的条件。提出了一种选择其质量和惯性特性的概率方法。
