摘要
卫星通信伺服系统的跟踪精度是决定卫星通信质量的关键性能指标,从天线安装误差、角传感器误差、惯导不同组合等方面逐一分析,并提出了采用电平跌落法进行精度的定量检测,实现了对伺服系统跟踪精度的有效试飞与评估,对后续卫星通信试飞具有很好的借鉴作用。
Tracking precision of servo system is a key performance indicator to determine the quality of satellite communication. The antenna installation error,angle sensor error,different combinations of inertial navigation system are analyzed.The 'level-drop'method is proposed and effective test and evaluation of tracking precision are realized. The method has great reference value,and can be used in similar flight test subjects.
