摘要
采用卫星仿真工具包对全球卫星导航系统包括GPS、Galileo、Compass等导航卫星星座的地面站天线方位、俯仰跟踪特性进行了仿真分析,以大口径地面接收天线为例讨论了可行的地面站天线座架形式和跟踪体制,并综合常规卫星通信抛物面天线精度分析方法和测控雷达天线的精度分析方法对跟踪精度进行了系统的分析,分析结果可作为今后类似系统的设计参考。
The azimuth-elevation tracking performance of the ground station antenna in the global navigation satellite system including several satellite constellations such as GPS, Galileo, Compass system and so on has been simulated and analyzed by using satellite tools kit. Then , as an example, antenna pedestal mode and tracking mode feasibly for the large-diameter antenna in the ground receive system are discussed, and analysis of the systematically tracking precision has been given by adopting an analysis method which synthesizes the precision analysis methods of the satellite communication parabolic antenna and the measurement radar antenna. The result is aimed to be beneficial reference for designs of the similar system.
