The invention discloses a Beidou III phased array agile inter-satellite link telemetering downlink path searching method, for a grounding node, a Ka station does not generate telemetering data, and the telemetering data of other satellites can reach a ground system without passing through an inter-satellite link, so that the grounding node does not need to search a telemetering data downlink path;for peripheral nodes, telemetry data of satellites are forwarded to a ground system through inter-satellite links in a multi-hop mode, and therefore downlink paths of the telemetry data need to be searched for. According to the Beidou No.3 phased array agile inter-satellite link telemetering downlink path searching method, the corresponding downlink path can be searched by using the inter-satellite link, and the telemetering data of each satellite can be transmitted back to the ground system through a plurality of hops. 本发明公开了一种北斗三号相控阵捷变星间链路遥测下行路径搜索方法，对于接地节点，Ka站不产生遥测数据，其它卫星的遥测数据也不需要经过星间链路即可到达地面系统，因此，接地节点无需搜索遥测数据下行路径；
