摘要
为提高卫星天线跟踪的精度,应尽量减小天线在安装过程中的误差。分析了天线在安装过程中可能产生的各种误差,并在此基础上得出了包含误差补偿的控制计算模型。通过对太阳的跟踪实验,计算出了各种安装误差值,将其补偿到控制软件中。实验结果表明可以获得较好的效果,提高了卫星天线的跟踪精度。
In order to enhance the tracking accuracy of satellite antenna,the installation error of antenna should be as small as possible. The thesis analyses various possible error during the period of installation, and based on the research, the control computing model including error compensation is obtained. By the sun-tracking experiment, various installation error is calculated and compensated into control software. The experiment results show that the software exhibited excellent effect and the tracking accuracy is enhanced.
