Design Of Miniaturization For On-Board Electronic System

With the development of the small especially the micro satellites, the demand ofsatellite for on board electronic becomes highly to achieve the characteristics ofsmaller size, lighter weight, lower power consumption, higher performance, shortermanufacture cycle and more quantity. It is necessary to integrate the on boardelectronic system effectively and rationally by using use high density integrated devicedesign, new structure and new design to reduce the mass, weight and to increase theperformance of the satellites.The topics intends to get the purpose of improving the reliability, cutting thedevelopment cycle and reducing cost by modularizing hardware and software designand using standard and modularized interfaces.The subject gives a program of designing micro on board electronic system anddevelops a set of prototype by integrating the on board electronic system and doingresearch on redundancy and reconstruction of electronic systems. Comparing with theformer system, the mass, weight and the power consumption has been reduced greatly,and the arithmetic capability has been improved significantly. The test result indicatesthat the prototype meets the demand of design requirement.
