摘要: 频谱规划是无线通信领域的概念.介绍了在遥感卫星动力学设计中的动力学频谱规划方法,通过合理的动力性频率设计,避免星上周期性活动部件与低频密集模态的挠性附件因频率接近而发生耦合振动,确保高精度遥感探测卫星具有足够的指向精度和姿态稳定度.以某高轨遥感卫星为例,通过规避5项干扰力矩对卫星的影响,确保指向精度和稳定度指标的实现.

Abstract: Frequency spectrum planning is a concept in the field of wireless communications. In this paper, the use of frequency spectrum planning in dynamics designing of remote sensing satellites is presented. Onboard resonance between periodic moving parts and the structure dynamics can be avoided by planning the spectrum of frequencies. A remote sensing satellites on geostationary orbit is taken for example. Five interference torques onboard are prevented from affecting the specifications of the mission.

Key words: dynamics frequency spectrum planning, attitude stability, coupled vibrations
