Large Capacity Multiplex And Memory Unit Based On Spaceborne Integrated Electronics System Equipment

With the great development of space technology, more and more use of satellite and spacecraft platform can carry the panchromatic camera or payloads such as measurement and control of high speed large capacity real-time scientific data, which makes the space technology in the field of integrated design and the status of a data processing system is more and more important. Integrated electronics system is satisfied in the proper selection of equipment integration design, and its data processing unit is the key to solve these problems, this article is based on a satellite integrated electronic equipment for large capacity data storage provides multiplex solutions.The technology of data multiplex and memory described in the paper include multiplex data sources, multi-storages and multi-output. The paper introduced a combinative design of FPGA and embedded So C. It utilizes the high speed data handle capability of FPGA and the flexibility of So C, realize the subarea access and management for multiplex data sources and data playback, as a result it enhances the real time and availability of data. The space data from payloads were packed and RS encoded according to CCSDS AOS recommendation, and design a test equipment for data validation.The research will be wildly applied in the spacecraft's payload data handling unite and will be have significative value for space missions in future.
