The antenna pointing control is open loop control without feedback . the antenna pointing errors due to antenna tracking motion and satellite attitude adjusting ( trusting ) were analyzed , as well as the influence of damping , tacking velocity and trusting time
文章分析了天线作跟踪运动和星体作姿态调整时，对星体姿态控制精度和天线的指向精度影响，同时分析了阻尼、跟踪速度、喷气脉冲宽度等因素变化对动力耦合程度的影响。
