摘　　要：卫星天线定位机构对控制天线的运动精确具有重要的意义。本文介绍了卫星点波束天线双轴定位机构的基本组成,建立了刚体动力学模型、仿真模型,并开发了仿真软件,对系统进行了仿真。The position mechanism of antennas is an important part of satellite for controlling the antennas' moving precision. In this paper, the basic form of two-axes position mechanism of satellite antennas has been introduced, and the dynamical models and simulating models have been established, finally, a simulating software is designed for the system simulation.

关 键 词：卫星点波束天线 双轴定位机构 仿真系统
