Design And Implement Of Integrated Services Unit For Satellitic Electronic System

The Integrated Services Unit（ISU）is the key part of the Integrated ElectronicSystem(IES) on satellite. Based on the main idea of modularization, standardization andthe objective of reliability, Universalization and modernization, some equipments of thesatellite platform electronic system were integrated and optimized to reduce the volume,mass, power and failure factor of the Electronic System on satellite.This Paper is the brief introduction to the ISU. It is through the research on thedomestic and overseas technology, to develop the system structure and a scheme of ISU.The design and fabrication of the CPU module of ISU was accomplished. Through thedesign, analysis and comprehensive testing, the problem about technology of theinternal bus，radiation of FPGA and based technology of designing the whole ISU wassolved. The CPU module was satisfied to its original design. It is the foundation of thedesign and manufactory of the ISU.
