Based on the background of future remote sensing satellites needs, This thesis is a research on the application of Advanced Orbiting System(AOS) in the high data rate space link, which is based on the Consultative Committee for Space Data Systems(CCSDS) recommendation for AOS. It puts forward a scheme of data processing and transmiting which according to AOS system, designs and implements a demo of High data rate Data Multi-connect Encoder.In order to transmit the multi-path dynamic asynchronous data and increase the utilization ratio of the physical channel, the virtual channel is deployed and multiplexed with dynamic priority system. Multi-path dynamic data can be transmitted with high-efficient and high-quality through one physical channel.A model of the High data rate Multi-connect Encoder is set. Its inputs are six high speed bitstream data. Then the functions of every part in the model are described respectively, functional and timing simulation are done to Multi-connect Encoder, the results are satisfactory. Multi-connect Encoder chip which is designed base on FPGA device and PCB board are finished. The result of experiment indicates that Multi-connect Encoder can multiplex six high speed bitstream data rightly, and the data format is according with the CCSDS AOS standard. The results are consistent with the theories. Demonstration the high bit rate AOS and its key technologies, as well as the verification of the scheme design and its availability. The research raises an available design method for the application of Multi-connecting in the remote sensing satellites data system research.
