摘要
针对亚太6E卫星地面信关站逐步建设需求,提出了一种适用于多波束高通量通信卫星的转发器馈电链路多模式设计,可以通过全部3个信关站管理所有用户波束,也可以通过灵活切换馈电链路工作模式采用1个信关站或2个信关站管理所有用户波束。当卫星在轨工作时,信关站可以向卫星发送控制指令,实时切换馈电链路的工作模式,以适应不同数量信关站的建设情况。亚太6E卫星在轨验证结果表明,该模式切换功能满足信关站逐步建设的需求。
For the requirement of APSTAR-6E satellite to gradually build ground gateway stations,a multi-mode design of transponder feed link for the multi-beam high-throughput communications satellite is presented,which can manage all user beams by three gateway stations,as well as manage beams by one or two gateway stations through flexible switching of feed link modes.When the satellite is working in orbit,the feed link modes can be switched in real time by sending commands from the gateway station to the satellite in order to adapt to the construction of different number of gateway stations.By the in-orbit test of APSTAR-6E satellite,the mode switching function can meet the needs of gradual establishment of gateway stations.
