在轨地球同步卫星轨道控制参数计算及工程实现

在轨地球同步卫星轨道控制包括东西、南北控制和位置漂移三个部分.分别针对这三种情况,从工程实用角度出发,给出了选择目标参数方法、控制参数计算公式和具体实施策略.以自旋卫星为例,分析了控制效率,提出了一种新的东西控制参数计算方法,在给定控制精度下,大大简化了算法的复杂性.以1904年9月FY-2B星一系列控制为例,详细介绍了它们在经度漂移、南北控制、刹车控制和定点捕获等方面的具体应用和实现效果,理想的控制效果表明了上述算法和实施策略的正确性. 

Orbit Control Strategies and Implementation for on-Orbit Geostationary Satellites

The controls of west-east station keeping, longitude drifting control, north-south station keeping are the main tasks of the orbit control. From the engineering point of view, many practical formulas to calculate the objective and control parameters are presented here. They have been successfully used for a series control of the China FY-2B on-orbit satellite, which is required to move from 104.5°E to 123.5°E for evacuating the position for upcoming FY-2C satellite in Sept., 2004. During the control process, the longitude drift, north-south station keeping, attitude adjusting and spin speed control are made. Their perfect results show the correction of these practical formulas and strategies.
