地震地带卫星天线伺服技术的研究

卫星天线地基发生变化时,天线对星的相对位置就发生变化,使得原有的通讯链路中断,为使通讯链路尽快恢复,必须依赖相应的的天线伺服设备的功能,重新捕获并对准卫星。从工程应用的角度,阐述了解决这一工程问题的基本思路,并且从实践的角度对这种能自适应大地地理位置变化的卫星天线伺服控制技术进行了研究,并着重介绍了在此基础上研发的伺服跟踪设备的主要功能设计原理及实现方式。为解决特种天线的伺服跟踪技术问题提供了一种新的思路。

Research on Satellite Antenna Servo Technology in Earthquake Zone

When the foundation of satellite antenna changes, the relative position of antenna in satellite pointing also changes, then the original communication network breaks off. To recover it as soon as possible, the function of the antenna servo equipment has to be relied on for the antenna to capture and point to the satellite again. In this paper, the basic way of resolving this engineering problem in engineering application is described, this satellite antenna servo control technique adaptable to the variation of geographical position is studied in terms of practice, and the main functions, principle and implementation method of the equipment are introduced, which provides a new idea for solving the problem of special antenna servo technique.
