摘要
随着卫星通讯技术的不断发展,卫星的数量不断增加,对卫星天线伺服设备的要求也越来越高,为了保证系统的不间断通讯,同时避免对空间微波环境产生不必要的干扰,高可靠的天线控制器起到了重要的作用。特别是大口径的卫星天线,由于其波束宽度窄,对天线的角度控制要求更高。介绍了一种基于系统级单片机的实用型大口径卫星通讯地面站天线控制器的基本设计,阐述了该系统的设计特点,并对主要部分的软硬件实现方式进行了说明。
Along with the continuous development of satellite communications technology, the number of satellites increases continuously, and the requirement for satellite antenna servo equipment becomes higher and higher. Highly reliable antenna controller plays an important role in ensuring the unintermittent system communication and avoiding the unnecessary interference to the spatial microwave environment. Large- aperture satellite antenna,in particular, has higher requirement for the angle control of the antenna due to its narrow beam width. The paper introduces the basic design of a practical large-aporture antenna controller for satellite communication earth station, which is based on system- level single chip micreprecessor,presents the design features of the system, and explains the software and hardware implementation method of the main parts.
