[Abstract]:Satellite integrated electronic system is a system for collecting, processing, distributing and storing information. It is a system for synthesizing information and function of space electronic system with high density and complexity under harsh space constraints. Integrated electronic system and satellite structure mechanism, thermal control, attitude and orbit control, energy system constitute satellite platform, the design level determines the platform performance of microsatellite to a great extent, and satellite platform technology is a symbol of the maturity of space technology in a country. As the overall system of microsatellite, the integrated electronic system is the electrical system and information center of the satellite, and plays an important pillar role in the operation of the satellite. In this paper, the function synthesis and data synthesis of microsatellite integrated electronic system are studied. From the point of view of function synthesis, the modular open system, bus system and software system of microsatellite are put forward. The development of satellite data technical standard is described from the point of view of data synthesis, and according to the characteristics of microsatellite application, the (CCSDS) conventional in-orbit system (COS) data standard of the International Spatial data Systems Advisory Committee is selected to realize the data synthesis. Based on the domestic industrial foundation, the integrated electronic system of SAST50 microsatellite is designed according to the integrated modular integrated electronic system (IMA), including the standard module division of integrated electronic system, telemetry, remote control, information flow, software, power supply, structure, data standardization and standard module design, which realizes the functional synthesis and data synthesis, which is open and universal, and embodies the advantages of modular integrated electronic technology. The products of microsatellite integrated electronic system have been tested according to the requirements of aerospace, and the system docking and receiving grade products have been tested. The test results show that the technical index meets the development requirements, which lays a solid foundation for the development of SAST50 platform and has engineering application value.
