摘　　要："中继卫星"作为天基资源可以为空间飞行器用户提供实时的数据中继和测控转发服务,日益得到广泛应用。但实际应用中,中继卫星受信道带宽和转发器功率限制,同时服务的空间用户数量有限。为解决该问题,提出了一种多用户"分时复用"使用策略及具体的实现方法,包括中继卫星信道资源划分、系统分时复用设计和分时复用约束条件等内容。在实际应用中,使得有限的中继卫星资源能够服务更多的空间用户,发挥更大的实际效能。The relay satellite, which is a space-based resource, becomes widely used and provides data relay and forward control service for space vehicles in real-time mode. The relay satellite can only service a certain number of space vehicles because of limited channel bandwidth and repeater power at the same time. In order to solve this problem, proposed a time-multiplexed strategy and practical implementation method, including the relay satellite channel division, system design and time-multiplexed constraint conditions. The limited satellite resources can service more space vehicles and play a more important role in protocol application.
