【摘要】：当前,卫星通信事业发展迅猛,现有C、Ku频段上可提供的频率资源日趋紧缺,可供给临时申请宽带交互式新业务的频率资源更是稀缺。因此,急需拓展新的通信频段。Ka频段能够提供3.5GHz可利用频率带宽,从而为宽带卫星通信业务寻找到一条新的路径。本课题研究设计Ka频段卫星地面站是国内第一个Ka频段卫星地面站天线伺服系统。论文首先阐述了天线伺服系统的工作原理,组成及技术指标。然后设计了Ka频段天线伺服系统的三大主要部分:天馈分机、结构分机和伺服控制分机,选定各部分的解决方案。论文对设计的天线伺服系统主要技术指标进行估算,各项结果均满足技术要求。工程结束后,验收人员进行测试,结果证明,该系统完全满足用户提出的需求,能够为卫星地面站提供良好的服务。
[Abstract]:At present, the satellite communication industry is developing rapidly, the frequency resources available in the current CU Ku band are becoming increasingly scarce, and the frequency resources available for temporary applications for new broadband interactive services are even scarcer.Therefore, it is urgent to extend the new frequency band. Ka band to provide the available frequency bandwidth of 3.5GHz, so as to find a new path for broadband satellite communication services.The research and design of Ka band satellite earth station is the first Ka-band satellite earth station antenna servo system in China.Firstly, the working principle, composition and technical index of antenna servo system are introduced.Then three main parts of the Ka-band antenna servo system are designed: the sky feed extension, the structural extension and the servo control extension, and the solutions of each part are selected.The main technical specifications of the designed antenna servo system are estimated, and the results meet the technical requirements.After the completion of the project, the acceptance personnel tested, the results show that the system can fully meet the needs of users, and can provide a good service for the satellite earth station.
