一种地球静止轨道自旋卫星东西控制参数计算方法及应用

提出一种新的地球同步在轨自旋卫星东西位置保持控制策略,它可以在给定控制精度下,达到传统算法同样的控制效果,但大大简化了过去算法的复杂性.同时还进一步分析了影响自旋卫星轨控效率的因素,给出了相应的提高措施,这些方法都已成功地运用到我国风云二号卫星的在轨工程测控上.

A Simplified Algorithm for Calculation of West-East Station Keeping Parameters for Dual-Spin Geostationary Satellites

This paper presents a new algorithm to calculate control parameters for west-east station keeping for dual-spin geostationary satellites.With the same accuracy provided by traditional ways,it is simpler and easier to understand.Also,the relationship between orbit control efficiency,rotation speed and width of engine impulse is explored.High orbit control efficiency can be achieved by selecting appropriate width of thrust pulse.These strategies have been successfully used in controlling China's operational FY-2 satellites.
