| 摘 要： | 为了获得中继星的星-星指向控制中天线捕获所需设计参数,对中继星和用户星之间的运动关系进行了分析计算。分析结果表明,天线捕获时间是用户星相对中继星运动速度的函数,因此,也分析计算了用户星相对中继星的运动速度,最终给出了中继星天线捕获时间、捕获速率和用户星运动速度以及扫描螺距之间的关系曲线和公式。

| Abstract: | In order to obtain the design parameters required during the antenna capturing process in the satellite pointing control of the relay satellite,the movement relation between relay satellite and user satellite was analyzed.The result proves that the time to capture of antenna is a function of the velocity of the user satellite relatively to the relay satellite.The relation curves and formulas between the antenna capture time,the capture rate and the velocity of user satellite were deduced after analyzing and... |
