    • A satellite communication system comprises: - at least one base station (1); - at least one satellite (2) which can be brought into communication connection with the base station (1) for data transmission; and - a plurality of receivers (32) adapted to receive signals transmitted from the satellite (2); - wherein the communication system is designed • to transmit data in at least one uplink data stream (U) from the base station (1) to the satellite (2) with a first data transmission rate and • to transmit data in at least one downlink data stream (D) from the satellite (2) to the receivers (32) with a second data transmission rate; - wherein the first data transmission rate is lower than the second data transmission rate and - wherein the satellite (2) is provided with a data storage means (22) adapted to store the data transmitted from the base station (1) to the satellite (2) and to supply the data provided for the transmission to the receivers (32).
    • 卫星通信系统包括: - 至少一个基站(1); - 至少一个可与基站(1)进行通信连接的卫星(2)进行数据传输; 以及 - 适于接收从所述卫星(2)发射的信号的多个接收器(32)。 - 其中所述通信系统被设计为以至少一个上行链路数据流(U)中的数据以第一数据传输速率从基站(1)传输到卫星(2),并且在至少一个下行链路中传输数据 数据流(D)从第二数据传输速率从卫星(2)到接收机(32); - 其中所述第一数据传输速率低于所述第二数据传输速率,并且其中所述卫星(2)设置有数据存储装置(22),适于将从所述基站(1)发送的数据存储到所述卫星 并且将为传输提供的数据提供给接收器(32)。
