摘　　要：卫星通信网中的通信卫星寿命有限,当接近寿命末期,必须使用其他卫星进行替换,即卫星通信网全网转星问题。重点分析了卫星通信网转星过程中需要解决的问题,主要对转星前的准备工作、转星实施步骤、转星过程中不同类型天线可能面临的问题,以及极化隔离度的测试等问题做了较详细的阐述,对卫通网的转星工作具有一定的参考价值和指导意义。The life span of the communication satellites in the satellite communication network is limited.When the communication satellite is near the end of its life span,it must be replaced by another satellite.The problems that need to be resolved during the satellite replacement process are analyzed,and the preparations for satellite replacement,the implementation steps,the problems that different types of antennas may face and the polarization isolation test are elaborated,and the discussion has certain reference value and guiding significance for the satellite replacement in the satellite communication network.
