摘　　要：随着甚高通量卫星系统的快速发展,信息传输速率已经达到太比特量级,现有的卫星通信系统主要以微波链路传输为主,难以支撑将航天器采集的数据及时回传至地面网络,因此,激光微波混合链路卫星通信系统成为发展趋势,研究微波激光混合链路传输的可用度成为关键问题。由于卫星通信系统可用度主要受卫星关口站所在当地天气因素的影响,卫星关口站建站位置的好坏直接决定了发送和接收卫星信号质量的好坏,同时也会影响资金投入以及安装、使用、维修是否方便等多个实际问题。文中根据实际应用需求,从自然因素和人为因素两方面对关口站选址进行了分析,并根据所选关口站站址,设计了各关口站所配置的链路功能,进而分析了激光微波混合馈电传输的链路可用度,为高速卫星通信系统关口站选址和馈电链路配置提供技术支撑。With the development of Very-High-Throughput-Satellite system, the information transmission rate has reached at tera-bits. The existing satellite communication system is mainly based on microwave link, which transmission rate is difficult to surport the transmission of data to the ground network in time. Therefore, hybrid microwave and laser link satellite communication system has become the main trend of development, and the availability analysis of this system has also become one of the research hotspots.Note that the availability of satellite communication system is mainly depend on weather, the location of gateways can affect the quality of signal, and affect the cost of construction. Therefore, in this paper, we consider both nature factors and human factors during the selection of gateway position. Then, the transmission availability of microwave and laser link is analyzed, which surports the construction of wideband satellite system.
