摘要
本文首先论述重力梯度卫星三种控制方式（重力梯度，重力梯度＋飞轮，重力梯度＋磁控＋飞轮），其次研究重力杆和天平动阻尼球结构设计与参数分析。最后建立重力梯度卫星数学模型和进行仿真实验。对小卫星来说，重力梯度既能满足性能要求又是廉价的一种姿态控制方法。
In this paper,major advantages of gravity gradient small satellites are frist described,such as simple as simple structure,high reliabity,low cost,short development time and light weight A mathematical model and some technical performances of gravity gradient small satellite are then presented Dynamia characteristics of this mathematical model are finally analysed by computer simulation
