| 摘 要： | 介绍了用扭摆,通过倾斜安装测量卫星三个方向转动惯量的一种方法。分析了IYY测量准确度和测量倾斜角大小、IYY/IXX的比值、倾斜角误差之间的关系。当倾斜角度θ〉45°时,IYY能够达到较高的测量准确度。

| Abstract: | Introduces a measurement method of moment of inertia for the artificial satellite through mounting the satellite with the angle of inclination. The measurement accuracy for the moment of inertia which related with the ratio between Irr and Iss and the sloping angle are analyzed, and conclusion is indicated that higher accuracy is achievable when the sloping angle greater than 45°. |
