通讯卫星的需求日益增大。原有卫星正在逐渐接近寿限,轨道缝隙越来越小,传送信息的需求量越来越大。现代卫星总线能满足这些需求吗?为此需作一番详细考察。 典型的卫星总线系统,包括天线和必要的控制系统以及卫星的机械结构、转发器和信号混合/放大器。 多数制造商都有一系列标准系统部件,客户选择卫星总线配置力求符合他们的需求。根据卫星买主或经营者达 The demand for communication satellites is increasing. The original satellites are gradually approaching the life limit, orbit gap getting smaller and smaller, the demand for transmitting information is more and more large. Can modern satellite buses meet these needs? Typical satellite bus systems include antennas and necessary control systems as well as satellite mechanical structures, repeaters and signal mixers / amplifiers. Most manufacturers have a range of standard system components, customers choose satellite bus configuration to meet their needs. Depending on the satellite buyer or operator
