    • A satellite broadcast system and method, particularly useful for television signals, allows for local as well as nationwide broadcast service by allocating greater satellite resources to the more important local service areas. This is accomplished by broadcasting a non-uniform pattern of local service beams and designing the system to establish different service area priorities through factors such as the individual beam powers, sizes, roll-off characteristics and peak-to-edge power differentials. Frequency reuse is enhanced by permitting a certain degree of cross-beam interference, with lower levels of interference established for the more important service areas.

    • The new satellite communications repeater test method allows multiple transponders to be tested from a single ground test station. The satellite's receive antenna is aligned with the ground station antenna and uplink test signals are transmitted to the satellite. The uplink test signal is converted to a corresponding downlink signal which is distributed to the transponders fed by the receive antenna. Prior to transmission from the satellite, the amplified downlink signals are sampled and combined and/or switched into a single path having a frequency spectrum which includes the frequency bands of the sampled downlink signals. The combined signal is transmitted to the ground test station from a wide angle transmit antenna. The received downlink signals are measured and stored for later processing to validate the operational characteristics of the transponders. In an alternative embodiment, the sampling and combining matrix includes switches for selecting the sampled signals to be combined.
    • 新的卫星通信中继器测试方法允许从单个地面测试台测试多个转发器。 卫星的接收天线与地面站天线对准,上行测试信号传输到卫星。 上行链路测试信号被转换为分配给由接收天线馈送的应答器的相应下行链路信号。 在从卫星传输之前,将放大的下行链路信号进行采样并组合和/或切换成具有包括采样的下行链路信号的频带的频谱的单个路径。 组合信号从广角发射天线发射到地面测试台。 接收到的下行链路信号被测量和存储用于后续处理以验证应答器的操作特性。 在替代实施例中,采样和组合矩阵包括用于选择要组合的采样信号的开关。
