摘要： A dual phased array payload (100) for use onboard a communications satellite is disclosed. The payload includes one or more phased array receive antennas (102-108) including numerous individual receiving elements distributed in a predetermined configuration. Each of the individual radiating elements is selectively adjustable in amplitude and phase to achieve scanning beams for receiving information transmitted from the ground in an uplink beam. The payload includes a packet switch (114) connected to the phased array receive antennas (102-108). The packet switch (114) includes a set of inputs and a set of outputs. The set of inputs are selectively connectable to the set of outputs. The payload (100) includes one or more phased array transmit antennas (120-126) connected to the packet switch (114). The phased array transmit antennas (120-126) include numerous individual radiating elements distributed in a predetermined configuration.

摘要： An adaptive transceiver architecture which reallocates communications resources in real time based on the amount of bandwidth being used in communications channels in the system. The transceiver receives communications signals from a plurality of communications beam spots. Each communications beam spot has a predefined bandwidth divided into non-overlapping subbands. The transceiver further comprises a plurality of front end signal conditioners for receiving communications signals from an equal plurality of communications beam spots. A predetermined number of the conditioned signals are then combined by an interconnect. The interconnect receives composite signals from the front end signal conditioners, and it combines at least first and second communications signals from first and second respective composite signals to form an output processing signal. The first and second communications signals are received by the receiver from first and second communications beam spots, respectively, and the first and second composite signals are output from the first and second corresponding front end signal conditioners.

摘要： A method of packet concatenation in TDMA transmission is provided. The method includes the step of transmitting from a terminal in a first time slot (202), including overhead information (108-112) and symbols representing terminal data (114). The method also includes the step of transmitting from a terminal (possibly the same terminal) in a subsequent time slot (204-208), including a subset of the overhead information (108-112) and symbols representing terminal data (114). The subsequent time slot may be a consecutive time slot. The overhead information may include, for example, guard time (110), ramp time beam settling time (108) and a preamble (112).

摘要： A method is disclosed for efficiently transmitting large numbers of data channels through a satellite (24). The method uses a block encoder (28) that encodes the data channels with a block code to produce an encoded uplink data stream. A modulator (30) modulates the encoded uplink data stream. A transmit antenna (32) then sends the resultant modulated uplink data stream (34) to the satellite (24). The satellite uses a satellite demodulator (48) and a switch (50) to produce an internal data stream consisting of selected data channels in the uplink data stream (34). The internal data stream is fed into a convolutional encoder (52). The output of the convolutional encoder (52) is connected to a satellite modulator (54). The satellite transmit antenna (56) then sends the resultant modulated downlink data stream (58) to a receiver.

摘要： A satellite communication system (10) includes apparatus for exchanging communication data between ground-based user sites (21-24, 41-44 and 51-54) and a ground-based wideband network (60). A communication satellite (30) exchanges user communication data with the user sites. Ground-based hub terminals (27, 35, 47 and 57) exchange the user communication data with the satellite (30) and also exchange the data with the network (60). A communication manager (70) determines the communication requirements between the satellite and the network and identifies more than one hub terminal to exchange user communication data with the satellite in the event that one hub terminal is insufficient to meet the communication requirements.
